[0002] Steel truss is a truss made of steel bars as upper chord, lower chord and web, connected by resistance spot welding. The steel truss and the bottom plate are connected by resistance spot welding to form a combined load-bearing plate called steel truss floor deck. Steel truss floor deck is currently used in multi-storey factories, multi-storey and high-rise steel structure buildings, various irregular floors, concrete structures, high-speed railways and other structural and construction fields. Because of its economic, convenient, safe and reliable characteristics, more and more builders and owners choose more scientific and more efficient steel truss floor deck. This device is the hoist used to hoist steel truss floor deck;
