In actual engineering projects, the size and specifications of floor decks often vary according to needs. This limitation not only limits the scope of application of the lifting workpiece, but also greatly reduces its practicality in actual applications; more importantly, when performing multi-story floor deck lifting operations, the lower floor deck is often squeezed due to the weight of the upper floor deck and the pressure during the lifting process. This squeezing may not only cause the lower floor deck to deform, affecting its structural stability and service life, but may also cause potential risks to the quality of the entire project. Therefore, we have introduced a lifting workpiece for steel truss floor decks. Utility Model Content
