The braking-shoe is loose, it doesn't break off the braking-wheel totally, and causes friction. The gap between two braking-shoe and braking-wheel is not even, or the gap is too narrow. The assistant-[...]
The reasons are as following: the leverage hinge is stuck, braking-wheel and friction plate have oil pollution, electromagnetic core doesn't have enough travelling distance, braking-wheel and friction[...]
Overhead crane working speed includes lifting speed, trolley travelling speed, overhead crane travelling speed. Working speed is influenced by many factors. First, it is related to the weight. The ove[...]
The reason is that fork can't absorb the transmission error, guiding-rail has poor straightness, and lifting rack is loose. The right way is to modify tractor, adjust the straightness of guiding-rail,[...]
The main reason is the temperature is too high, the distance between lifting racks is too long or loose. It is useful to adopt anti-heat plate partially, add sun shield outdoors, increase the number o[...]
The reason is that electric brush climbs in the conductor, the brush wears seriously, conductor joint is not smooth, single connector is used, rail joint becomes loose. The correct way is to check whe[...]
First is through flexible cable. The power of the lifting overhead crane is supplied by AC power system. Because the work of the overhead cranes is movable, the overhead crane and the power can't be c[...]
Electric hoist overhead crane mainly includes lifting mechanism, travelling mechanism (trolley travelling mechanism and overhead crane travelling mechanism) and rotating mechanism. First is lifting me[...]
PLC is the abbreviation of programmable logic controller. Its basic structure are composed of power, CPU, memory, input/output interface circuit, function module and communication module. PLC can chan[...]
Before using the cantilever crane, the operator should check whether the switch button and the wire rope stopper are faulty. If there is any problem, it should be repaired in time before use, and it s[...]
