The safe use of cranes three components

 To ensure the safe use of bridge gantry crane  three members, to prevent accidents, which requires the use of units and each crane operator must:

    First, to ensure that anti-decoupling device intact hook, hook should be used with anti-collision; should wash to each lubrication point refueling; find bottom, the rim at the crack, break or excessive wear to the timely replacement pulley. To ground inspection hook body, hook mouth found cracks and wear more than 10% of the original thickness and an opening degree of change, should be timely rectification. It is noteworthy that, hook welding defect can not be processed.

    Second, the wire rope when in use, should avoid sharp turns. Crane from the (system) move, plus (minus) the slow speed required to prevent excessive force while Bengduan rope.  overhead gantry crane  in the power line next job, pay attention to the power line to ensure adequate safety distance power lines to prevent the rope hit and burning. When the rope and buildings, equipment, sharp contact, should be fitted wood. Wire rope should be neatly arranged on the roll, not confusion, to avoid pressure damage. In the welding wire rim not prevent high arc and weld slag rope burns. The rope is too short not to take the long way then reused. To strengthen the maintenance of wire rope, often with kerosene and other cleaning agents to wash away the dirt on the rope, and note the oil dip immersion rope. Operation, the operator should check once a day rope, mainly to check whether the wire rope wear, broken wires, corrosion, changes in diameter as well as other physical and chemical changes, and pay attention to check the end of a fixed rope situation.

    Third,  Steel crane  operation, the operator must carefully check whether the brake parts in normal operation, for jams, shoe clearance is appropriate, brake wheel surface is good, the adjusting nut is tightened. For brake lubrication should be carried out twice a week, but be careful not to stick in the friction lubricant components. If the brake shoe, brake wheel, small shafts, spindles, etc. excessive wear; main spring, auxiliary spring breakage or plastic deformation occurs; brake wheel cracks, etc.; brake solenoid, power failure and other hydraulic stacker lever should be repaired, not sick to run, to ensure safety.
