The electric chain hoist can be used on wind power equipment. It is a special lifting equipment with a lifting capacity of up to 1000 kg and a lifting height of up to 130 meters. It can be installed on thejib crane or mobile gantry crane for quick and easy lifting the tools and components. The chain electric hoist is equipped with a chain bag, and the chain can be put into the bag.This electric chain hoist shell is made of high-strength aluminum alloy, thin-walled extrusion forming, precision manufacturing, high-pressure die-casting to avoid the generation of air holes during the forming proce ...
After the column mounted jib crane is installed, the test should be carried out.Before the test, add 30# mechanical oil to the middle of the oil mark in the rotary reducer (oil change once every half year). When commissioning, first press each button to check whether the running direction and the control button match. If they do not match, should adjust or replace.No-load test: The electric hoist should run smoothly on the left and right sides of the beam and rise and fall. The cantilever beam should be flexible and stable when it is rotated, and should stop at any position without slipping, a ...

1. Before gantry crane using, check the track for any sundries, and pay attention to the presence or absence of wires and other obstacles affecting the work;2. Before each operation, carry out test hanging: lift the heavy object from the ground for about 200mm to test if the brake is reliable, can be lifted after confirming safety;3. When working, the wire rope should be lifted vertically. Otherwise, the lifted objected will swing, collide with other objects, even cause the crane rollover accident;4. The gantry crane should not be overloaded; when working under heavy load, it should be run slo ...
* The brake action is flexible and reliable, the adjustment should be tight and moderate, no cracks, the spring has no plastic deformation.* When the brake wheel is released, the gap between the brake shoe and the brake wheel should be substantially equal. The brake belt opening (one side) should be ≤ 1 mm and the lift should be ≤ 0.7 mm.* The brake friction surface of the brake wheel shall not have any defects that impede the braking performance, and shall not be contaminated with oil or paint.* The unevenness of the wheel surface roughness should be <1.5 mm. The thickness of the wheel fla ...
