>Brief introduction

The HSZ series chain block is a portable lifting device easily operated by hand. It is suitable for using in factories, agricultural production, wharfs, docks and storages for fixing machines, lifting cargoes, and loading and unloading goods. It is especially advantageous for lifting work in the power supply is not available.The chain block can be attached to a trolley of any type as a traveling chain block. It is suitable to monorail overhead conveying system, hand traveling crane and jib crane.

>The components

A:Chain block have the advantages of high ability ,security and agility, because of this point ,The working intension is reduced greatly with long life time.

B:Gear:High speed synchronous gears;they are arrayed symmetrically and made in terms of the international gear steel standard ;Compared with the common gears,they are more steadier and laborsaving.

C:Chain:Adopts the high precision welding technology which meets the ISO3077-1984 international standard;Suitable for gusty overload working conditions;Can achieve the purpose of better hands feeling; Multi-angle operation(with 45°).

D:Hook:Made of high-class alloy steel,it has high strength and security with new designation.

E:Limit Switch:Using limit switch component in order to protect chain and ensure security.

F:Components:Main components are all made of high-class alloy steel with high precision and security.
