Detailed Description

1. Gear

They are innovated symmetrical arrayed high speed synchronous gears, and are made of international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving.

Standard international gear steel is two times as wear-resisting degree as the ordinary chain block, rotation is more stable and hand pulling force is more light.

2.Chain

Adopt high strong chain and high precision welding technology, meet ISO3077-1984 international standard; fit for gusty overload work conditions; bring your hands a better feeling; multi-angle operation:

changing the ordinary chain block only vertical downward pull, fit to greater scope.

Hand Chain: material A3, 30 grade,galvanized,

Lifting chain: material 20MN2, G80 grade,black.

3.Hook

Made of high-class alloy steel, it has high strength and high security by using the new design. andmake sure the goodswill not be decoupled.
4.Limit switch

Using limit switch component in design to protect the chain and ensure the security.

Both upper and bottom hook have limit switch part prevent chain escaping.
5.Components

The main components are all made of high-class alloy steel, with high precision and security.
