(Summary description)    

The lifting pulley is a simple lifting machine that vertically lifts the weight through a sprocket or reel. It is light, compact, easy to use, suitable for simple lifting work in construction. Depending on the number of wheels, the lifting and original supports can be divided into single-door slides, double-door pulleys and multi-door pulleys. There are four types of high-hook impactors, sprocket cyclists, suspension ring skateboards and sling pulleys are divided into hooks, sprocket cyclists, suspension ring sliding and sling pulleys. Efficient use of labor-saving vehicles can achieve half the effort. The following permanent magnet hoist manufacturers will take you to understand.

 



 

 

The manufacturer of the permanent magnet hoisting device tells you that when the direction of the lifting pulley changes, or when the hook pulley is not used in high altitude operations, it is not recommended to use the hook pulley to prevent the hook from being removed. If hanging pulleys are used, protective measures should be taken. If after the hook, the hook is sealed with a thin wire so that the hook cannot be taken out; or use a hook with a tube, when the hook is hung, the hook is more convenient. Under the action of the spring, the Caucasian is bounced up and seals the hook.

 

The manufacturer of the permanent magnet hoist tells you that the pulley cannot be overloaded. When there are cracks or defects, the pulley will not be put into use. Other parts, such as hooks, shafts, pull plates, etc., are not allowed to be used when required. When walling, you should pay attention to the angle of the wire rope in the pulley box. In any case, the deviation of the pulley shall not exceed 4°~6°. Because when the polarity of the wire rope is too large in the pulley box, the abrasion of the wire rope and the side of the pulley are intensified. On the other hand, the wire rope can easily slip out of the rope groove, so even if it is an accident, the lifting operation cannot be performed normally. If only one of these bags is used, the weight should be reduced accordingly, and the original weight cannot be used.

 



 

 

The manufacturer of the permanent magnet hoist tells you that when the pulley block is worn out, you should try it first, check the part, there is no casing, friction or wire rope. If there is anything, it should be officially adjusted to formal. The rope that wears the sling or pulley block must meet the requirements of the pulley. When the diameter of the wire rope used exceeds the requirement of the pulley, we will increase the wear of the pulley, and the wear of the wire rope will also increase. The weight of the pulley must be equipped with corresponding thick steel wire.
