Experts Guide to Advanced Lifting Technology
The capability of safely moving large, heavy loads forms an integral part of industrial manufacturing. Naturally, such enormous loads cannot be relocated manually, hence lifts and hoists can be utilized to shift materials to new locations. 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.
The slipform method of construction involves pouring concrete in a continuous and steady manner (theconstructor.org, SLIPFORM CONSTRUCTION METHOD, 2015). This technique is mainly used for building tall and complex structures such as skyscrapers, towers, bridges, dams, etc. In this technique, concrete can be poured in a non-interrupted and balanced manner. Slipforming is basically of two types: vertical slipforming and horizontal slipforming. In the former type, vertical structures such as the ones mentioned above are built by pouring concrete around framework components, which have been set up before. A sub-type of this method includes conical slipform construction technique, which is mainly used to build round and conical structures, especially with changing cross sections. Some examples of these structures are industrial chimneys and bridge pillars (slipform-austria.com, CONICAL SLIPFORMING, 2013). In contrast, horizontal slipforming, as the name suggests is used to make horizontal constructions such as roadways.
Lifting operations are fairly common on construction sites. These operations may be carried out manually or with the use of lifting equipment. Manual lifting operations can only be carried out for loads of a certain weight. Heavy lifting equipment must be used to raise and lower loads that are extremely heavy. Any lifting operation, whether manual or mechanical, puts workers at the risk of injury. Construction sites are vulnerable to accidents during lifting operations. This is why it is important to ensure workers’ safety during heavy lifting operations. Some tips to improve safety on a construction site are mentioned below.
