The rate at which novel construction techniques are being introduced in the market is making the construction industry to constantly evolve. Along with that, there is also considerable growth in the types of heavy lifting equipment available for different construction processes. This is enabling companies to choose suitable equipment from several options available.
When it comes to selecting or procuring lifting equipment, construction companies need to consider multiple factors just to be very sure so as to carry out all the processes without any complications. Heavy construction equipment transport is one of the common problems faced by companies. To solve this complication and other such issues bridge-building companies need to make the following considerations while procuring a lifting system.
There are multiple options available in the market when it comes to lifting systems. Each of the systems has a whole lot of characteristics that are suitable for each of the processes. One of the most important factors that companies should consider while procuring a lifting system is; is the system capable enough to lift the required amount of goods and materials. Is the system equipped enough to lift any kind of loads without causing a breakdown midway and thus not causing a hindrance in the process? It is most essential to check the load capacity of the system to carry out any process seamlessly.
Crane lifting equipment are designed to lift heavy loads and there are no two ways to it. But not all cranes can fit in all kinds of construction sites. The reason being, cranes and lifting systems are made in different variations. Not only according to their load capacity but also their shape and size. This ultimately decides how mobile the equipment is. One of the main limitations crane equipment can face is how far the reach of it is. Construction companies can take a call on the kind of cranes to be selected only depending on the area of worksite available.
As construction companies are involved in building structures/bridges of different heights and measurements, it becomes important for them to have cranes to reach to those different heights without any complication. That being said, the selected type of crane should also be equipped enough to reach tall heights as safety concerns are always a priority. As a result, companies should always be sure of which type of equipment to choose after gauging the height of the structure to be created. Investing in crane equipment that falls short of the height to be reached, proves to be waste monetarily.
Dimensions & Weight
As bridge-building companies make use of a whole lot of equipment while constructing a bridge, making sure the equipment is of the right size and weight before using it on the construction site is essential. Considering this becomes important because these factors decide the durability of the equipment. It also gives construction companies better clarity about which particular worksites each of the cranes can be used. As a result, being completely aware of the dimensions and weight of crane enables companies to make better decisions thus ensuring a smooth construction process.
Bygging-Uddemann’s expertise and equipment can assist bridge building projects in several ways. We can design the slipform for bridge pylons, towers and columns, lifting systems for handling the falsework for sectional casting of the bridge span, and we can launch pre-constructed steel bridges.
Bridges are considered to be an important part of the infrastructure industry. Irrespective of the size, shape, and length, the effort that goes in while constructing a bridge is humongous.
When construction companies receive a project of building bridges, they have to consider various factors. Factors like location, usability, type of technology to be used and more. Along with that, they also have to decide and choose from various types of bridge building techniques including precast, cast-in-situ, incremental and more.
The different types of bridges that bridge building companies design are as follows.
Truss Bridge Construction
Truss bridges construction involves detailed soil analysis. The reason being, it is constructed depending on the suitability of the bridge and traffic loads. This type of bridge is ideal when a combination of multiple pressure and compression forces are going to be applied. A truss bridge typically provides a built-in support system which comprises of squares and triangular pieces which are used to balances forces and provide support to loads. This type of bridge is designed either with the road being at the truss bottom or with the road being at the truss top. Typically, the types of truss bridges include:
- Howe Truss
- Lenticular Truss
Beam Bridge Construction
When there is a need to create a construction to cover a road, water body or even a valley, beam bridge construction is used. This is known to be the most common type of bridge building. Its is used for shot spanning distances and perfect to carry light loads. Beam bridges can be as simple as they can get and make of even wood beams. Besides wood beams, these bridges are also fabricated of concrete beams. This bridge type consists of a beam that is laid across the piers and support which handle the pressure put on it.
Cantilever Bridge Construction
Cantilever bridge construction involves this type of bridge having support on one or both ends. The basic aim of this type of bridge is to attach the segments in an alternate manner at opposite ends of cantilevers supported by piers. Bridge launching is easily adaptable due to this type of bridge especially for irregular and long span lengths, congested project sites, rough and water terrain, rail crossings, and environmentally sensitive areas. Cantilever bridges are quite rigid in nature because of which they are able to carry heavy loads without the fear of breaking down.
Cable Bridge Construction
Cable bridge construction is the most common type of bridge option when it comes to bridge building. This type can be built either using concrete or steel, but more often than not, the combination of both these materials is used. Since the construction of this bridge is sturdy, it is strong enough to hold horizontal platforms which acts as the main surface for construction. Many of the famous bridges in the world are built using this type.
Bygging-Uddemann’s lifting systems are suitable for practically all kinds of heavy loads whose placing or removal require a high degree of precision. We supply feasibility studies, erection of buildings, assembly work and training and supervision of your own construction team.

Accurate Control Over the Equipment
Using heavy lifting equipment requires proper knowledge and expertise. As a result, the workers making use of the equipment should be aware of the functionalities in order to operate it accurately. This gives them the required control over the equipment thus making their tasks easier and faster.
Awareness About the Surrounding
When workers operate in a new environmental surrounding, there are possibilities of accidents happening. This is one of the main reason that workers should be entirely aware of the surroundings they are working in and how their crane lifting equipment reacts to the workspaces. Knowing the surrounding helps them to operate the equipment in a more aware state of mind.
A piece of equipment is a machinery that is bound to misfunction at some point in time. Hence, before workers start making use of any kind of equipment, it is important to know the things that could go wrong and plan steps to curb such situations. This keeps workers safe at all times.
When tall structures in concrete are to be built, slipform construction is usually seen as the best-suited building method. What does the term slipform mean exactly? Simply put, slipform is the name given to the hydraulically controlled formwork into which concrete is poured. It is widely used in construction projects and is also called the continuously formed or slipform construction method. The well-known method is used for the construction of tall structures such as dams, bridges, buildings, and towers.
So, why is slipforming so commonly used? Slipform is undoubtedly the fastest and most economical construction method available for high-rise concrete structures. This is because it helps to provide an uninterrupted and continuous process for concrete that sets quickly. There are different types of slipform construction such as traditional (vertical) and gantry supported, as well as tapered and conical slipforming.
What is Slipform Construction?
Nowadays the way businesses build concrete structures has evolved enormously as compared to earlier times. It now included the utilization of the latest machines and equipment available in the market and the adoption of new construction methods that can simplify complex construction processes. Read on to know more about the meaning, benefits, applications, and components of slipform construction below.
As mentioned above, this type of construction method entails concrete being poured into a continuously moving form. As the slipform method largely depends on the quick-setting properties of concrete, a great deal of balance is required to be maintained between its workability and quick-setting capacity. What are the advantages of slipform construction?
Benefits of Slipform Construction
There are multiple advantages of using this technique for construction such as the following:
Of course, safety comes first. Slipform construction greatly reduces the risk of workers getting injured on site. This is through the system’s use of small increments in the climbing process that is connected to the structure at regular intervals.
As the slipform construction setup is highly compact, it can be pre-assembled and saved the precious time of the workers.
Slipform assembling companies come highly recommended by many businesses as they offer a quality finish, with cost and time-effective as well as sustainable use of materials.
Slipform Construction – Uses, Components, and Features
Traditional slipforming is one of the oldest and most conventional slipforming methods used. It involves the use of hydraulic jacks along with other equipment in order to raise the levels of structures. It is mainly used in the construction of tall structures such as domes, skyscrapers, and towers.
The conical slipforming method is a more developed version of traditional slipforming with the main difference in this technique being the change in the length of the cross-section diameter, as the variation depends on the height of the structure being constructed. The change in the cross -section is what eventually results in the conical shape of the structure.
Originally, conical slipforming was developed to construct concrete structures, with continuously changing dimensions like wall thickness. These thick walls are among the main features of slipform construction. The thickness of the wall constructed depends on multiple factors along with the cross-sections such as the size of the cone, the material used in construction and of course, the height of the structure.
The tapering slipform method of construction is to construct high rise structures efficiently, which helps to reduce the duration of construction projects. In traditional slip forming, the concrete formwork can also be surrounded by a platform for the on-site workers to stand on as the concrete is poured.
Applications of Slipform Construction
The applications of conical slipforming are seen in the construction of oil platforms, cooling towers, industrial chimneys, bridge pillars, and other tall concrete structures. Generally, these types of structures involve the changing thickness in shapes, diameters, and walls. While the technology was initially developed for constant cross-sections with precise vertical orientations, it was later further developed for use in variable layout shapes. This process provides a monolithic construction method that enables the easy increase and decrease of layouts. Businesses can learn more about conical slipform supply by contacting a reputed construction equipment company.
What is a gantry? It is a steel-structure that can house a platform. This type of slipform construction utilizes a gantry to build and support various construction equipment. Gantry slipform has now replaced the traditional slipforming method in the construction of repeated concrete structures such as caisson production. Developed as a more cost-effective option, it foregoes the need for dismantling and reassembling during construction as well as the use of cranes. It has also proven to be much more convenient and safer for on-site workers because of the additional space for them to move around and store equipment.
Unlike the traditional slipform method, which requires continuous installation of jack tubes for the slipform jack to climb on, Gantry Slipform Method has the climb tubes and jacks completely outside the caisson geometry. This facilitates the work because they and never interferes with the rebar installation. The jack rods will also last for the complete project.
Advantages of Slipform Construction
Due to speedy industrial development, a large number of buildings, harbours, chimneys, LNG- tanks, etc. are annually constructed using slipform construction technique. The main advantage of slipforming is that the formwork is erected only once but remains intact until the entire project has been completed. With the implementation of careful construction processes such as conical slipforming, companies can achieve higher rates of production. Some of the other benefits of opting for the slipform construction methods are the minimal use of cranes, the need for a much smaller workforce, and the resulting availability of different working platforms. While there are a few minor disadvantages of slipform construction, they are outweighed by the advantages offered.
Safety tips for Slipform Construction
Building with slipform construction provides the safest, quickest and most economical results. As it does not require any dismantling and reassembling using heavy pieces of equipment, the entire process is very secure. The method uses hydraulic slipform jacks that allow the whole construction formwork to be continuously raised at a height. To learn about safety tips for slipform construction, businesses can contact reputed slipform engineering or slipform construction specialists and also get a better understanding of slipform construction
The process of bridge construction is a long and complex one. Since bridges are often built in crowded urban or topographically sensitive areas, construction companies follow a defined process for safety purposes.
As a concept bridge launching is about the designing and construction of different kinds of bridges using techniques like incremental bridge launching, heavy lifting, precast span-by-span technique and many more. Since bridges are considered to be vital infrastructure development, its construction process is dependent on a lot of factors. Factors like region, climate, accessibility, etc. Based on these factors, the construction technique is decided.
Many times incremental launch is the best-suited method since it requires a small geographic space. The reason is that the method is executed from one end of the bridge only. The principle of the incrementally launched bridge consists of building/placing the bridge superstructure behind the bridge abutment. The entire superstructure is then jacked forward by employing hydraulic jacks.
Even though different kinds of bridges demand different construction techniques, all bridge-building techniques primarily focus on the following three main areas of a bridge.
The foundation of any type of bridge is extremely crucial from all perspectives. It sets a base for the whole structure which further defines its formation. A foundation holds the shallow or deep base of the bridge. Depending on the depth, the foundation is divided into two, i.e, shallow foundation and deep foundation.
A shallow foundation is a type that spreads the structural load to soils that are nearer to the ground surface. They transfer loads to the ground through bearing pressure. The deep foundation on the other hand, as the name suggests goes deeper into the soil and spread structural load accordingly. While deep foundation transfer loads to the ground through bearding pressure along with transferring loads by friction with the soils along the length of the foundation.
The substructure is that area of the structure fabricated with the help of piers, abutments, caps, spandrels, bearings and other such components. This part of construction holds the upper construction in place and supports the superstructure by transferring the structural load to the foundations.
The design of each substructure differs as there are various factors involved like different soil conditions, site location as well as the weight of the structure which differs from project to project. The substructure of the bridge consists of the portion of the bridge that supports the entire structure on the given surrounding soil which gives the structure a more fixed shape to further lead to the fabrication of the superstructure.
The main and final area that bridge launching is based on is the superstructure. A superstructure is that part of the structure of the bridge which directly takes the load and transmits to the supports on either side. Building the superstructure firmly is highly crucial for supporting the bridge completely.
Superstructure covers all the element mounted on top of the supporting substructure system. These elements include slab, decking, girders along with everything every element placed above the main deck such as bridge girder, posts, cable-stayed system, steel truss system, cable-suspended systems etc

Hence, selecting the appropriate size and type of construction equipment is important. They must have a combination of versatile characteristics like a vast lifting capacity with a long reach along with flexible configuration, quick mobilization, as well as a relatively small footprint to provide significant improvements in construction and turnaround efficiency. It is also mandatory for construction planners, supervisors and site managers to possess in-depth knowledge about the features of the major types of equipment most commonly used in construction. Listed below are the main equipment used for loading and transportation purposes on-site.
What are forklifts and what do they do? These powerful industrial trucks are used to lift and move heavy materials across short distances. They are indispensable as they offer multiple applications across various industry sectors. Forklifts use rear wheel steering to improve their ability to manoeuver tight corners. Through the use of hydraulics controlled by levers, they employ steel forks to lift and transport material. One of the most common uses of a forklift is to transport materials stored on pallets.
Undoubtedly, one of the most well-known examples of heavy lifting equipment is a crane. So, how does a crane work? It uses a combination of one or more simple machines in order to carry heavy loads and material across construction sites. Being highly efficient heavy lifting machines, they are most commonly used in the construction and transportation industry for the unloading and loading of cargo freight and movement of heavy materials. They are manufactured in a variety of models that can be customized for specific purposes. Not only do cranes vary in their applications, but also in their sizes. Small to medium-sized cranes are used in workshops and garages while towering cranes are most often seen on the job sites of skyscrapers.
They are also known as teleporters, telescope handlers, or more commonly, boom lifts. While it is similar to a forklift in appearance, the application of a telehandler is more like that of a crane. It comes with an attached telescopic cylinder or a boom, that can easily extend upwards and forwards from the machine. The operators of the machines can attach additional accessories for heavy lifting such as winches, pallet forks, buckets or muck grabs. Telehandlers get their increased versatility from the use of a single articulating boom.
What are rod climbers? Rod climbers are flexible equipment that can easily handle large lifting from anywhere between 12-400 tons. They are highly useful in demanding environments that require a great degree of precision along with the placement or removal of heavy loads. Such climbers come equipped with parallel hydraulic cylinders that can be mounted between something known as grip-jaw heads. Rod climbers are used for moving loads upwards, downwards and sideways.

When using this equipment and machinery, there are significant safety issues that need to be considered. This is essential from the aspect of the devices, operators as well as workers in the vicinity. Staying up-to-date on the latest trends and developments in the ever-changing construction industry is paramount. This can be accomplished by doing research and consulting heavy lifting equipment companies and browsing expert guides on advances lifting technology. One of the most valuable technologies that have emerged recently is radio frequency identification (RFID). It utilizes a small disc or chip that contains all the information on a particular product. By scanning the chip, construction companies can understand everything from the date of manufacture of the equipment, certifications, history of initial inspections, replacement parts and much more. As more and more heavy lifting equipment manufacturers design and develop innovative products, companies must make an extra effort to stay abreast of new technology including ongoing education, conduction of regular inspection and safety training sessions and more.
The construction industry is constantly growing and coming up with new and innovative methods to create newer and improved structures. Architectural design and technological improvements have ensured that the construction companies do not fall behind on the growth. The way buildings are built have also evolved over the past few decades. There has been a steady improvement in the techniques and equipment used to construct buildings, bridges and more.
One of these new and evolving techniques is slipforming. Traditional slipforming consists of creating a premade formwork skeleton and then outpouring concrete continuously and in levels using different equipment. Below are a few main slipforming techniques that construction companies use to create stable structures:
Traditional slipforming is the oldest and the most conventional slipforming used. It uses hydraulic jacks among other equipment to raise structures in levels. It is mainly used in building high rise buildings, domes, towers and other tall structures. Construction companies may need to use different cranes while constructing using traditional slipform supply to lift beams, jacks and other concrete and construction material in this method.
The conical slipforming method is a developed version of traditional slipforming. The way this method works is nearly the same as the traditional variant. The main difference in this technique is the change in the length of the cross section diameter, with the variation depending on the height of the structure being constructed. The change in the cross section is what results in getting the conical shape of the constructed structure.
The thickness of the wall constructed depends on many factors along with the cross sections. Some of these are:
- The height of the structure
- The material used in construction
- The size of the cone
The structures that are built using conical slipforming as a construction method are chimneys, smoke outlets in factories, and even some forms of towers.
A gantry is a bridge shaped structure that houses a platform. Gantry slipform supply construction uses a gantry to build and support many different construction equipments. Gantry slipform replaced the traditional slipforming method in the construction of various objects and structures. It reduced the popularity of the traditional method in the construction of many high rise buildings, caissons, bridges, and more, all of which used the traditional slipforming method.
The gantry slipform method was developed as the more economical option. It does not require any dismantling and reassembling during construction and it does not need to use cranes as much either. It is also safer and more convenient for workers because there is more space for them to move around and to store equipment.
There are many different types of construction methods that vary on the type of the structure that is being built. Keeping in mind the various aspects of construction, construction companies can select the best one that fits in their model.
Combination of construction and technology has proven to be highly beneficial. New techniques of construction developed by construction companies have considerably reduced the time required for construction of large structure. Various equipment and machines have made processes in construction easier and have also reduced risks.
Some structures are difficult to build and require more money. One such structure is a bridge. Constructing a bridge is both difficult and costly. Since bridge building techniques require some work to be carried out under the water, construction becomes especially difficult. Maintaining strength of a bridge is another important matter
Bridge construction has two parts: construction and bridge launching. Bridges consists of two parts: a horizontal framework and the pillars. The horizontal framework is mounted over the pillars hence, the pillars are considered as supporting structures. It is important that the pillars are strong enough to bear the weight of framework as well as the traffic that will make use of the bridge. The best option for constructing a strong foundation under water is making use of caissons. Caissons are used for two major purposes:
1. Dry Workspace: A water tight hole dug under water provides space for the construction work. It also prevents infiltration of the water inside workplace and therefore keeps the work space dry. Hence, there is no hindrance caused by water during construction. This method is also known as pneumatic.
2. Foundation: In case of bridges or dams caissons are used to build a foundation underwater. The holes dug by driller are further filled with concrete. This provides a strong and sustainable foundation.
Caisson launching is thus a boon for construction underwater. Other advantages of this method are:
1. Can be used in various working conditions, and hence this method is used for construction of different structures.
2. Strong and sturdy construction is provided by this method, which makes it preferable method for bridges.
3. Cost effective method as compared to traditional methods.
4. Less vibrations as compared to traditionally built foundations.
For launching of bridges and caissons, heavy lifting equipment is used. There are various bridge building companies, which provide these heavy lifting solutions. Bygging-Uddemann is one such company. They provide heavy lifting solutions that can be used for launching of bridges and for slipform constructions.
With the growth in technology, bridge construction and design has also evolved. There are new bridge building techniques being developed that make the construction of bridges a faster and more efficient process. A lot of bridge building companies and construction companies use their technology to construct durable and long-lasting structures in a timely manner.
Factors Involved in Bridge Building
There are many factors that need to be taken into consideration by construction companies when it comes to bridge building. Companies need to confirm the scale of the bridge along with the time allotted to them for the construction. They need to check the obstacles that are being crossed with the building. The local weather and nature of the soil are different environmental factors that affect the construction of a bridge. Additionally, the local cost of the materials that need to be sourced and the local labour market available for hire are also crucial factors. Last, but not the least, the site’s accessibility is vital for bridge building companies to make a bridge.
Bridge Building Techniques
There are a lot of different methods and techniques involved in constructing a bridge. The cast-in-situ technique is used to construct complex and unusual geometric shapes. It is used when there is difficulty in transporting goods. The cantilever method of construction is used to construct long-span and cable-stayed bridges. The precast technique uses precast concrete elements in building bridges. There are different methods available for the prefabrication of the concrete elements used.
The incremental launching method makes the bridge decks in sections. This is mainly used in the construction of steel girder bridges or continuous concrete bridges. Cable-stayed bridges use cables to carry the bridge deck from the tower. The arch technique is the most economical bridge building technique when it comes to constructing a bridge over inaccessible landscapes. It uses the slip forming technique for construction.
Equipment Used in Bridge Construction
Building with slip-form construction provides the quickest and most economical results. It is also a very safe method of construction. It does not require any dismantling and reassembling using heavy pieces of equipment. The slip-form method uses hydraulic jacks that allow the whole construction formwork to be raised continuously at a height.
Transportation of heavy structures like prefabricated elements that are involved in bridge building can be a costly affair for construction companies. Ensuring efficient and safe transfer of goods is a priority. A combination method of hydraulic jack and slip technology for lifting and transporting heavyweights has been a successful and economical method of conveyance.
Heavy Lifting Equipment
Controlled handling of heavy material that is used in building bridges requires trustworthy heavy lifting equipment. Rod climbers and strand climbers are relied upon at construction sites because of their adaptability when it comes to the heavy objects that need to be carried safely. They can be used to install formwork structures, complete bridge sections, and for repair work
These were some of the important bridge building techniques as well as the factors and equipment involved in the process. It is essential that bridge building companies and construction companies maintain the highest standards of safety while carrying out their bridge building techniques.
Construction companies today use hydraulic equipment to carry out heavy lifting tasks. Cranes, forklifts and excavators are used to efficiently transport cargo and material on construction sites and in industrial areas. By using hydraulic equipment, even mammoth tasks are carried out with ease at the touch of a button.
