Quenched gear set: Ensures overall machine performance, doubles the drag coefficient, meets long-term overload requirements, and delivers smooth, jam-free lifting.
After undergoing 20 processing steps—including polishing, thickening, and quenching—the material boasts high tensile strength and a substantial safety factor.
Alloy casing with collision protection: made from alloy steel, integrally formed and thickened for enhanced impact resistance.
Alloy steel housing; thickened manganese steel hook; G80-grade manganese steel chain; streamlined slot design
Its core working principle is based on a ratchet-friction disc-type one-way brake, which enables the hoist to self-brake under load, thereby ensuring operational safety. It is particularly well-suited for operations in open-air, outdoor, or power-free environments.
The VD-type hand chain hoist is a portable manual lifting tool that uses human power to drive a chain and employs a gear transmission mechanism to lift or move heavy objects over short distances.

A hand chain hoist is a lightweight lifting tool that uses manual operation of a handle to lift, pull, or tension heavy objects.
The HSZ-type hand chain hoist is a compact, portable manual lifting device. Its chain length can be customized to meet the lifting requirements of various operational scenarios.
This hand chain hoist is suitable for equipment installation, cargo handling, and other operations in factories, construction sites, docks, warehouses, and environments without power sources.
