Technical Problem
Traditional lifting lugs, once welded onto steel structures, need to be cut off, resulting in material waste and damage. Furthermore, the hooks are prone to slippage, leading to safety accidents.
Method used
Design an adjustable prefabricated lifting lug, which uses a lug plate, mounting part and bolt connection, and is fixed to the I-shaped steel component by nuts and bolts. The lifting point is adjustable and stable by using springs, push rods and rollers, and the position of the lifting point is automatically measured by a torque rangefinder.
Benefits of technology
Adjustable installation of the lifting lugs reduces material waste, improves the stability and safety of hoisting, reduces the workload of manual measurement, and extends the service life of the lifting lugs.
