Lifting Beam for Handling Steel Structure Truss in Construction Sites
On construction sites, steel structure trusses (such as roof trusses and bridge trusses) are large, heavy, and irregularly shaped. These structures are prone to deformation, cracking, and even accidents during lifting due to uneven force. The hoisting beam (also known as the balance beam or shoulder-pole beam) is a core lifting component designed specifically to address these challenges. Its scientific mechanical design makes it a reassuring factor in truss lifting.
Why is the lifting beam a "must-have artifact" for truss lifting?
Disperse the load and protect the truss structure
The lifting beam is connected to the truss through multiple lifting points (usually 2-4), converting the concentrated pulling force of the crane into a uniformly distributed lifting force, avoiding excessive local stress of the truss (such as nodes and rods), and effectively preventing deformation, weld cracking and other problems. It is especially suitable for thin-walled, large-span light steel trusses.
Maintain balance and accurate alignment
The horizontal design of the lifting beam allows the truss to always remain horizontal during the lifting process. With the adjustable lifting point spacing (adapting to trusses of different spans), even special-shaped trusses (such as arcs and broken lines) can be lifted smoothly, greatly reducing the difficulty of high-altitude alignment and improving installation accuracy.
Extend the life of the sling and reduce costs
In traditional lifting, the sling is directly in contact with the sharp angle of the truss and is prone to wear and breakage, while the lifting beam can keep the sling and truss at a safe distance (connected through the lifting ears of the lifting beam itself), reducing the wear of the wire rope and sling, extending their service life, and indirectly reducing the lifting cost.
Adaptable to multiple scenarios, flexible and efficient
The length and material (such as Q345B low-alloy steel and aluminum alloy) of the hanging beam can be customized according to the weight of the truss (optional 1-100 tons) and span (adjustable 2-50 meters), which can not only meet the overall lifting of the truss of high-rise buildings, but also adapt to the truss transportation needs of different projects such as factories and bridges.
From prefabrication to installation, assisting the truss project throughout the process
Factory prefabrication: In the steel structure processing plant, the hanging beam cooperates with the gantry crane to lift the welded truss from the tire frame to the transport vehicle to avoid deformation of the rods caused by manual turning and handling;
Transportation and loading and unloading: After long-distance transportation to the construction site, the truss is quickly lifted from the truck to the stacking area through the hanging beam. When stacking in multiple layers, the spacing of the trusses is kept uniform to prevent mutual squeezing;
On-site lifting: At the construction site, the hanging beam cooperates with the crawler crane and the truck crane to accurately lift the truss to the installation position (such as the top of the column and the embedded parts on the wall), and cooperates with the workers to quickly complete the bolt connection or welding fixation.
