It can be installed separately on the I-beam or installed. Used on electric or manual single beam, double beam, cantilever, gantry and other cranes.

 

Before lifting, check the safety performance of the equipment. Whether the mechanical, steel wire rope and hook are fixed and flexible, the rotating part is flexible, the power supply, grounding, button, travel switch is good and sensitive, the stopper should be intact, and the left and right runways, pulleys and rolls Whether the cylinder, brake and installation are flexible, fixed and reliable, and must not be damaged. The motor and reducer should have no abnormality, and whether the wedge is installed firmly and reliably.
