Description

Combined gantry crane beam Technical Field The utility model particularly relates to the technical field of gantry crane hanging beams, in particular to a combined gantry crane hanging beam. Background In the field of modern industry, a gantry crane is used as a large-scale hoisting device, and can be widely applied to scenes such as ports and docks, railway goods yards, industrial and mining enterprises, bridge construction and the like by virtue of the characteristic that the gantry crane can realize vertical lifting and horizontal carrying of heavy objects in a large operation range. From loading and unloading of port containers, installation and transportation of factory large-scale mechanical equipment, and hoisting of bridge prefabricated parts, the gantry crane is indispensable key equipment, and the efficient and stable operation of the gantry crane directly influences the progress and efficiency of production and construction. The lifting beam is used as a connecting bridge between the gantry crane and the lifted heavy object, and is a core component for ensuring the safe and efficient lifting operation.
