How to avoid detachment during explosion-proof electric hoist

Explosion-proof electric hoist can be said to be a wide range of small machinery used in the lifting industry. Since it is small, light, light, easy to use, etc., it is favored, but it is wide, and there will be inevitable problems, recent The technical department received a lot of inquiry, saying that the use of explosion-proof electric hoists encountered a desorbed case.

Explosion-proof electric hoist uses rigorous gap, sank, torsion, super load, etc. There is a problem with the fixing method, and the fixation method of the screw is that after the 13 ball is assembled, the screw knife is screwed into the bottom of the screw into the bottom, and then riveting the outer side of the screw.

When the hook is subjected to gravity, the hook loop slot will give the ball an outward force. The buds are subject to the top of the ball, and when the outer end of the billet is not riveted, the buds Just exiting from the bore of the screw, with the bearing force and friction of the ball in the action of the external force, the hook and hook beam lost the ball from the bore, hook and hook beam The relative displacement occurs in the direction of the hook axis and the spoon is detached, and the serious situation can cause accidents. Regarding the explosion-proof electric hoist, it is mainly due to the above reasons. If you encounter other situations, you will be unblocked, welcome to exchange.
