Mainly engaged in single and double girder cranes, gantry cranes, shipbuilding cranes, bridge machine, grab, electric hoist and other lifting equipment manufacturing, sales and installation. Double girder overhead crane safety inspection in order to ensure the safe operation of overhead crane, crane operation during a routine examination in need of some security, inspection items and points are as follows: (1) lifting height limiter, travel limit switch and all interlock mechanism normal performance, safety and reliability. (2) comply with the safety requirements of the major components: the opening is increased less than 15% of the original size, the torsional deformation of less than 10%; hook bushing wear plate is less than 50% of the original size, the plate wear of the hooks is less than 5% of the mandrel, no peeling , burrs, welding. Hanger hook and pulley no obvious defects. The surface of the wire rope wear, corrosion wire diameter is less than 40%, the broken wires in one lay length within less than 10% of the total number of wires, no breakage, no thinning, no core part prolapse, dead twisting, extrusion annealing, burning phenomenon. Rope end connections and the fixed clip, clips, wedge block connection intact, no loose plate of not less than two, the number of no less than three catches. Roll no cracks, connect, fixed no loose; worn cylinder wall thickness of less than 20% of the original; secure volume of not less than two laps electric hoist gantry crane MHS, reel and wire rope diameter ratio of compliance. Balance wheel fixed intact, the rope should meet the requirements. Brakes no cracks, no loose, no serious wear, brake clearance on both sides of the right of equal size, there is sufficient braking force electric hoist gantry crane MHB type, brake band wear less than 50% of the original thickness. By double girder bridge crane safety routine inspection, to prevent accidents, reduce equipment accidents, improve equipment operation rate, reduce maintenance costs etc played a significant role.
