Dual-beam traffic shift inspection requirements (1) First, check the box to protect the total power switch is off, 32t double girder crane is not allowed live checks. (2) The wire rope is intact, with or without yarn breakage on the drum and the pulley in the winding is normal, with or without removal tank, channeling, knotting, twisting and other phenomena, the rope ends plate bolts are firm and reliable. (3) hook for cracks, whether permanent deformation, hook rotation is flexible, commercial dual-beam cranes, spreader is complete, reliable, Hezhou double girder crane hook pulley wear status. (4) whether the agencies abutting brake brake wheel brake shoes, brake pad and brake drum wear status, (5) bolts agencies transmission parts and each part is solid bolts. QZ Electric Bridge Crane Bridge Crane electric main bridge from the box, grab the car, traveling mechanism, cab and electrical control system. Extract device is able to grab the grab the bulk material. Grab a small car for opening and closing mechanism and the lifting mechanism, 550t double-girder crane, with four rope grab are hanging in the opening and closing mechanism and from the lifting mechanism. Opening and closing mechanism driven grab closed, grab material, after bucket mouth when closed, immediately start lifting mechanism, so that the average four rope hoisting work performed under load. Only start when the discharge opening and closing mechanism, then open bucket mouth, tilt the material. The crane hoisting mechanism in addition to play different, the remaining portions of the configuration is basically the same overhead crane 80t double girder crane dual-beam crane _ _ HeZhou generous heavy Ltd provided by generous heavy machinery in Henan Province.
