electric trolley hoist stop slip interval exceeds rule request
When the electric trolley hoist is out of service for a long time, some people mistakenly adjust the brake nut, or the brake ring wear is too serious, so that the brake spring pressure is reduced, the braking force drops, when the stop, the brake is not reliable, the sliding interval beyond the rule request, this situation as long as the electric trolley hoist instruction request, from the beginning to adjust the brake nut. But should pay attention to work, lifting heavy objects, stop adjustment, view and repair brakes.
Sometimes, adjust the braking nut, stop falling intervals are still beyond rules request, encounter this kind of situation, will think about other factors, the first open brake ring first, check whether brake surface with oil pollution, such as with oil, friction coefficient decline, can make the skid when braking, fall beyond the rules between requests, just adjust the braking nut use is not big, and completely clean the brake (clean and easy to use benzine), rehabilitation brake surface friction coefficient;
Second, if the brake ring is loose or damaged, the brake ring can not ensure useful braking, as long as the replacement of the brake ring; Sometimes find brake ring did not damaged, brake ring and rear end cover only touch the bad cone, brake, the brake surface touch, less braking force is too small, beyond rules request in interval, maintenance, in order to increasing the braking force, should find out a touch bad bearing, grinding, increase the touch surface when braking, failing to grinding, need to replace accessories;
If the electric trolley hoist coupling is not moving properly or stuck, the brake ring and the rear end cover cone face are not touched properly or cannot be touched after the machine is stopped, so that the electric trolley hoist brake action is good or bad. In such cases, the coupling should be repaired or replaced.
Other, brake pressure spring for a long time use of fatigue, so that the spring force smaller, stop, the brake is not strong, should replace the spring, from the start to adjust the braking force.
