The stopper device of the electric hoist is composed of a connecting rod, a positioning clip, a rope guide and a stopper. The stopper can avoid the hook being higher than the lifting limit, so as to avoid the failure of punching and breaking the wire rope, and ensure the stability of the equipment. If the installation is wrong, the protection function of the stopper can not be played, then how should we install and debug the stopper of the electric hoist?

1.Loosen the screws on the bumping block, the bumping block is placed on both sides of the rope guide card, and the card can freely push the bumping block to move. Start the motor to start lifting, the pallet pushes the upper bumping block to move, and stops rising when it rises to 15mm-50mm along the lower edge of the drum shell along the upper edge of the hook pulley housing. Press the down button, and when the rope guide moves back about 10mm, stop moving the upper bumping block near the pallet, rotate and tighten the screw.

2.The adjustment method of the lower limit is the same as the adjustment method of the upper limit, but the direction is opposite, but when the hook must be in the low position, more than 3 rings of wire rope are left on the drum. After the adjustment is completed, it is necessary to carry out no-load test run to check whether the installation of the upper and lower limits meets the requirements.
