When the quality of the friction plate of the hand chain hoist is not good or the machining precision of the contact surface is not enough, the friction plate will wear out with the increase of the use time, resulting in the occlusion between it and the other parts of the brake becoming unstable and the coefficient of friction decreasing, which will lead to the phenomenon of slipping. This kind of slippage not only affects the operation efficiency, but also may bring potential safety hazards.
In order to improve the performance and safety of hand chain hoists, modern friction pads use advanced production processes. Metal wires are added to the surface of the friction plates, which not only significantly increases the coefficient of friction, but also improves abrasion resistance and stability, resulting in a longer service life of the friction plates and a higher level of safety for the user.
Although friction pads are vital to a hand chain hoist brake, they are currently still a consumable item that cannot be effectively maintained. Once the friction pads are worn too thin, they need to replaced with new ones in a timely manner to ensure the normal use and safe operation of the hand chain hoist. Therefore, checking the wear of the friction pads regularly and replacing them with new ones when necessary are key measures to ensure the safe use of t he hand chain hoist.
