Classification and structural characteristics of hand chain hoists

1. Classification of hand chain hoist

According to the place of origin, it is divided into: domestic hand chain hoist, imported hand chain hoist

According to the shape, they are divided into: round hand chain hoist, T-shaped hand chain hoist, triangular hand chain hoist, mini hand chain hoist,

K-type hand chain hoist, 360-degree hand chain hoist, diamond-shaped hand chain hoist, V-type hand chain hoist

According to material, it is divided into: explosion-proof hand chain hoist, aluminum alloy hand chain hoist, stainless steel hand chain hoist

2. Functional characteristics of hand chain hoist

When the hand chain hoist lifts a heavy object upward, the manual chain is pulled clockwise and the manual wheel rotates, pressing the friction plate ratchet and brake seat into one body to rotate together. The long tooth axis rotates the plate gear, the short tooth axis and the spline hole gear. In this way, the lifting sprocket installed on the spline hole gear drives the lifting chain, thereby lifting the heavy object smoothly.

When descending, pull the hand chain counterclockwise, the brake seat is separated from the brake pad, the ratchet is stationary under the action of the pawl, and the five-tooth long axis drives the lifting sprocket to run in the opposite direction, thereby smoothly lowering the heavy object.

Hand chain hoists generally use ratchet friction plate one-way brakes, which can brake themselves under load. The pawl engages with the ratchet under the action of the spring, making the brake work safely.

The hand chain hoist has the characteristics of safety, reliability, easy maintenance, high mechanical efficiency, small bracelet pulling force, light weight and easy to carry, beautiful appearance, small size, and durability. It is suitable for factories, mines, construction sites, docks, docks, warehouses, etc. It is used to install machines and lift goods, especially for open-air and non-power supply operations, which shows its superiority.
