Three parts safety use of gantry crane
The Three parts is Crane hook, wire rope and brake. To ensure the safe use of the three components of the gantry crane, 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 in anti-collision; to wash the lubrication points to refuel; found at the crack, break or wear to the timely replacement of over-standard pulley. To ground inspection body hook, hook mouth found cracks and wear of more than 10% of the thickness and the degree of change when opening, it is timely rectification. It is worth noting that the defect cannot hook welding processing.
Second, the wire rope when used should be avoided acute angle turns. Crane starting acceleration and deceleration are required to slow and prevent the rope to disconnect by excessive forces. Pay attention to ensure adequate safety distance when the crane’s position next to the electricity power lines, to prevent the rope hit power lines and burning. The equipment should be wood mat when the rope sharp nearby the building. Rope should be neatly arranged on the roll, not chaos, to avoid pressure damage. Not welding wire rope edge, to prevent high temperature arc and weld slag rope burns. The rope is too short not to take the long way to re-use. To strengthen the rope maintenance, often with kerosene and other cleaning agents wash away the dirt on the rope, and attention will dip immersion rope lubricants. When the job, the operator once a day to check the wire rope, wire rope careful to check for wear, broken wires, corrosion, diameter change and other physical and chemical changes, and note that the fixed end of the rope to check the status
.
Third, when the crane operation, the operator must carefully check whether the brake parts in normal operation; if the jam; shoe clearance is appropriate; the braking surface is good ethics; adjusting nuts are tightened. The lubricating of brake should be twice a week, but be careful not to stick lubricant on the friction parts. When the brake solenoid malfunction, power poles and other hydraulic pile; if the brake shoe, brake wheel, small shaft, spindle, etc. excessive amount of wear; the main spring, helper spring break or plastic deformation occurs; brake cracks, etc. due to be repaired, not sick to run, to ensure safety.
