1.Sealed Gearbox 

A sealed planetary gearbox complies with heavy duty cycles ; the gears are heat treated and mounted on high strength and low friction bearings to enlarge the life span.

2.Chain and Guides

Grade 80 load chain is applied as standard. The chain guide escorts load chain shift rapidly on load sheave without twisting.

3.Precise Controller

Pendent control or toggle control offers variable speed control with accurate and precise positioning of loads.

4.Safety Brake

Non-asbestos disc brake is applied automatically when the air supply to the hoist is shut off.

5.Upper/Lower Limit

The hoist switches off automatically while hooks reaching the highest or lowest limits; limits won't sway while hosting up or down to extend the service life.

6.Integral Silencer

The design to exhaust through the gearbox reduces the noise in the air and offers the cooling effect on the gearbox.

7.High Strength Housing

High strength nodular graphite cast iron housing ensures shocks,bumps and corrosion resistance.

8.Vane Motor 

The spring assists vane lifting when air supplied ensures maximum torque without delay while starting loading.

9. Mechanical Overload Device

It's a protection device to prevent overload. We design two disk springs to control the ring gear and lining reaction. We set up 125% capacity, the hoist will be slipping when it's overload.
