The electric bridge cranes lifting height limiter
time:Oct 19,2016
On the electric bridge cranes, the lifting height limiters are basically equipped. The lifting height limiter can serve to limit the height of the pick-up device. If the spreader rises to the limit position, the height limiter can automatically cut off the power supply, stop the lifting mechanism to prevent the hook from continuing to rise and collide to damage the spreader and the reel, or even break the wire rope and cause the heavy object to fall down.
The lifting height limiter is composed of the stroke switch and concave and convex strips, structure is relatively simple, operation is accurate and reliable, can be reliably avoid the accident. In general, the maintenance of lifting height limiter should be paid attention to ensure that the electric bridge cranes can work normally.
