Electric hoists represent their own machinery, strength, and toughness, while the stage is elegant, flowing, and soft, with conflicts and collisions between the two.

Product Details
The lifting of electric hoists can be carried out based on the actual situation on the construction site, using a crane for installation or using a winch with pulley blocks for lifting; When hoisting, protective measures must be taken to prevent damage to the equipment by tying the rope. According to the weight of the equipment itself, rope slings should be selected for hoisting. Gap adjustment
The clearance between the inner side of the walking wheel flange of the electric hoist and the flange of the I-beam rail should be ensured to be between 3-5 mm, which is achieved through shim adjustment. This is a key and must be achieved. Adjustment of motor spindle displacement
When the axial displacement of the main shaft of a conical rotor motor is generally 1.5mm, the braking effect is the best. If the electric hoist slides too much under rated load, it needs to be adjusted. The adjustment method is as follows:
Remove the tail cover. Unscrew the four screws that secure the adjusting nut, use a wrench to turn the adjusting nut clockwise to its limit position, then turn it counterclockwise one more turn, and then install the fixing screw. Adjustment of the cut-off limiter
The adjustment of the cut-off limit device is achieved by adjusting the two collision blocks on the limit rod. The adjustment method is to loosen the screws on the collision block, place the collision block on both sides of the rope guide card, and the card can freely push the collision block to move. Start the motor to start lifting, and the clamp plate pushes the upper limit collision block to move. When the upper edge of the hook pulley shell is 150mm~50mm away from the lower edge of the drum shell, stop lifting, press the lowering button, and when the rope guide moves back about 10mm, stop the machine. Move the upper limit collision block close to the clamp plate, and tighten the screws. The adjustment of the lower limit position is the same as above, but in the opposite direction, but it must be ensured that when the hook is in the lowest position, there are more than 3 turns of steel wire rope left on the drum.
