Reasons for slippage of hand chain hoist

The hand chain hoist is an advanced version of the ordinary pulley. The hand chain hoist uses reverse brakes and chains. After it lifts the object, the object will not fall (unless the chain is broken or artificially). It is suitable for short-distance lifting of small equipment. transport. It has the characteristics of small bracelet pulling force, relatively light weight, high mechanical efficiency and easy to carry. It is widely used in factories, mines, construction sites, docks and other places, and can easily complete the short-distance lifting of small equipment and goods. However, after using it for a long time, some problems, large and small, will inevitably occur. For example, slipping of the hand chain hoist is common. There are many reasons for the hand chain hoist to slip, but most of the reasons are because the brake pads inside the hand chain hoist are worn. If this is the case, just replace the brake pads. The length of time for hand chain hoists of different manufacturers and brands No, a good quality hand chain hoist will last longer.

Hand chain hoists all use single pawl brakes. If the spring on the pawl is loose, it will cause no braking, brake failure, and slipping. Therefore, when slipping occurs, we can first check to see if it is the pawl. The spring on it is loose, just replace it;

2. Another situation is that there is a problem with the friction plate:

① During continuous use, the friction disc will continue to wear. Poor-quality friction discs are easy to wear and not wear-resistant. They will become thinner and thinner, resulting in a reduction in the friction coefficient and slipping;

② If the friction plate is stained with oil, it will cause the friction coefficient to decrease, and of course it will be accompanied by slipping.

The friction plate used in WUYI hand chain hoists has advanced technology and has good stability and high wear resistance. It can be used longer and extend its service life, making our work smoother and more reliable.
