What's QGX Limit Switch?Qgx type lifting height limiter is applicable to all kinds of cranes, elevators, elevators and other equipment with displacement machinery. It is a safety protection device to limit the lifting bottleneck, and can effectively prevent equipment and personnel accidents such as jacking, derailment and falling.The lifting height limiter of qgx crane is equipped with four to six limit switches, which can be set according to the user's needs. Generally, two protections can be set for the rising and falling, namely, alarm limit and protection limit.How Does Qgx Limit Switch Working?The lifting height limiter of qgx crane drives the worm and worm wheel to rotate by the reel shaft, and the cam on the worm wheel shaft also rotates. When it turns to a certain position, the flange part of the cam contacts the limit switch to make the limit switch act, cut off the power source for lifting or lowering, and stop the lifting appliance at the limit position.Advanages1.
