On electric wire rope hoists, height limiters are basically equipped. The height limiter can 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, and prevent the hook from continuing to rise and lead to spreader, wire rope and reel damage, object falling.
The height limiter is composed of the stroke switch and the concave and convex strips. The structure is relatively simple, movement is accurate and reliable. In general, the maintenance of the height limiter of the electric wire rope hoists should be paid attention to ensure that it can work normally.
