Crane inspection items

electromagnetic overhead craneOverhead crane safety inspection in order to ensure safe operation of the overhead crane, crane operation required during some routine security check on the project and highlights are as follows:
(1) lifting height limiter, travel limit switch and all the positive properties of interlocking institutions
(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 mandrel plate hook wear less than 5%, no peeling burr, welding. Hanger hook and pulley no obvious defects. The surface of the wire rope wear, corrosion is less than 40% of the diameter of the wire, broken wires in one lay length within less than 10% of the total number of wires, no breaks, no thinning, no core prolapse, dead twisting, compressional deformation annealing, burning phenomenon.electric hoist manufacturers
End connections and fixed rope clips, clips, wedge block connection intact, no loose plate at least two, the number of no less than three catches. Roll no cracks, connections, fixed no loose; cylinder wall wear less than 20% of the original wall thickness; secure volume of not less than two laps, reel and rope diameter ratio of compliance. Balance wheel fixed intact, shall comply with the requirements of the rope. Brakes no cracks, no loose, no serious wear, brake clearance on both sides equal right size, there is sufficient braking force, brake wear with less than 50% of the original thickness.
By conventional overhead crane safety inspection, to prevent accidents, reduce equipment accidents, improve equipment operation rate and reduce maintenance costs etc play a significant role.
