Working technology parameters of bridge crane
Working technology parameters include lifting capacity, lifting height, span, mechanism working speed, working class, crane weight and wheel pressure.
Lifting capacity is that the maximum lifting weight under normal condition.
Lifting height is the distance between up-limit position and down-limit position.
Span is the distance between two ends of the crane.
Mechanism working speed includes lifting speed, crane travelling speed, trolley travelling speed.
Operation class shows the degree of loading and working times. It includes low class (A1-A3), medium class (A4, A5), and high class (A6, A7) Super high class (A8).
Overhead crane brake system
A brake is a mechanical device that inhibits by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.
Tips of low headroom overhead crane
Brake is an important part of crane, brake condition is related to other parts’ accuracy and reliability. In order to ensure crane good condition, the brake of lifting mechanism and luffing mechanism should check timely.
Pay attention to reducer. Check whether the reducer is oil leak, whether the box has abnormal sounds when crane travels. For abnormal sound, it is because of shaft problem, large gear smashing gap or serious weariness.
Daily safety checkout of wire rope and load chain
Check wire rope and load chain by walking 360 degrees around the hook block and examining wire rope/chain.
Check that there’s no reduction in diameter.
Check that there are no broken wires.
Make sure there’s no kinking, cutting, crushing, or thermal damage to the wire rope.
Check that there are no cracks, gouges, nicks, corrosion, or distortion on any link of the load chain.
Ensure that there’s no wear at contact points.
Verify chain sprockets are operating smoothly.
