In the construction of low-rise buildings, most of the equipment responsible for vertical lifting tasks are gantry cranes dragged by winches. However, the gantry cranes of some construction teams are not equipped with hanging basketsLifting height limiterIf the electrical switch of the winch is out of control, the contact is stuck or the operation is wrong, it is easy to cause the basket to rise to the top beam while the motor continues to work, resulting in mechanical equipment damage, basket overturning and other accidents. In order to solve this problem, according to practical experience, our company made and installedLifting height limiterThrough several years of practical use in this city, it has proved to be effective.

If the basket is raised to the installation setting due to out of control contact adhesion, operation error, etcLifting height limiterAt, the upper beam of the hanging basket will jack up the < 6 yuan steel with the hinge as the center, exert pressure on the travel switch, restore the normally closed contact to the original position, make it connect the circuit, form a path through the resistance, generate instantaneous leakage, and the leakage protection switch will trip to cut off the winch circuit, thus playing a safety protection role
