The Gantry Crane Safety Inspection (TWO)-Jinrui Machinery

Second, walking mechanism inspection

Mainly to check the walking wheel tread, open gears, couplings, transmission bolts, traveling wheel axle oil hole and other parts, such as walking wheel surface hardness is not good; There is bulk ouerburden material; The Open gears, couplings should be equipped with protective cover; Timely tighten the loose transmission foundation bolts; Keep the wheel axle oil hole clear.

Third, metal structure inspection

Must pay attention to metal structures plastic deformation. The main girder arch is the key part of the gantry crane structure inspection, so as to avoid the gantry crane main beam arch disappear or even scatter because of overload and the heat radiation influence. In addition, should focused inspect whether the boom has bending, twisting or not; the boom, balance arm root plug ear plate, main girder web and under cover is split or not, etc.

Should caralfully inspect the joint bolts of gantry crane cantilever crane, portal crane Slewing bearing base and other structure parts, due to the combined action of frequent tensile, shear force, torsion forces and other force, there may lead to serious accident if not timely remove these faults, because of fracture from the root.
