HSZ-VD type chain block

The HSZ-VD type chain block adopts a highly technical symmetrically arranged high-speed synchronous gear structure. Made of international standard gear steel, this HSZ-VD type chain block features doubled wear resistance, smaller pulling force than ordinary models, and more stable rotation.

The HSZ-VD type chain block is equipped with a high-strength load chain with delicate welded joints, processed by medium-frequency furnace induction quenching in line with international standards. It withstands sudden overloads, offers an improved hand chain grip, and allows 45° multi-directional pulling, unlike conventional chain blocks that only support vertical downward pulling.

The HSZ-VD type chain block uses high-strength safety hooks forged from premium alloy steel with special treatment. These hooks deform gradually instead of breaking under sudden overload, and the new design effectively prevents cargo from falling.

The HSZ-VD type chain block is fitted with top and bottom limit switches for automatic shutdown to avoid load chain over-running. Key components of this HSZ-VD type chain block adopt high-quality alloy steel with strict dimensional control for reliable performance.

Featuring a slim, ergonomic design, the HSZ-VD type chain block is lightweight and suitable for various working scenarios. It has high-grade internal and external coating for lasting color, and its precision steel shell ensures a compact yet robust structure.
