What happened to the electric hoist's braking?
May be because the motor internal back in spring, there is also a kind of internal disharmony between dynamic bearing, may be outside of the electric hoist is a kind of problem is not run for a long time, there is no air in the brake, with rain soaked, also can brake lock, can put the brake loose and then it is ok to install, if the motor internal problems, recommend replacing spring and dynamic bearing and the bearing inner sleeve
In general are so for several reasons A chain due to drag and other crosslinking jammed 2 electric hoist shell deformation or abrasion cannot correct guidance within three electric hoist chain stuck four retarding mechanism and retarding mechanism deformation moving parts oil shortage caused difficult to ascend
It's for outdoor use. The brakes are in the water. Rust to one piece.I hope my answer will help you
