pneumatic chain hoist introduction
The Features of the air hoist
1.Overload protection
When the working load is heavier than rated load, the overload protection can make the hoist stopped so to make the hoist life longer.
2.Planetary gear
Two deceleration mechanism accurately and efficiently control the speed ratio.
3.Brake mechanism
Copper brakes effectively prevent sparks harm, and can accurately and efficiently control the hoist up and down speed.
4.Chain wheel
Precision anti-wear sprocket ensure the chain smooth lifting and lowering in the wheel and make the hoist life longer.
5.Air motor
Low air consumption, less maintenance time, high torque, transfer faster lifting speed.
6.Silencer
Internal silencer reduces noise when air excluding.
7.Air supply valve
Precise movement of the piston control the in and out gas so as to make the speed infinitely variable.
8.Protection without air
When the air supply is suddenly cut off, power transmission part will automatically lock the brake directly through the brakes,
9.preventing the load suspended matter in the air free fall.
10.Chain
T8 grade, Anti-aging, contains a sufficient amount of alloying elements alloy steel calibration chain.
11.Limit device
When the load is raised the top of the hoist, the stopper blocking will stop the load continue to be lifted, and open 12.brakes
immediately, so to ensure safety.
13.Chain bag
The size can be booked or can do metal bag.
14.Standard lifting hook
Can choose standard 360 degree rotating hook or copper plating hook which is used in special spark-proof situation.
15.Installation and commissioning
Main intake pipe use plug and play method to make installation very easy and convenient.
16.Pendant
Push-button handle accurately and efficiently control the raising and lowering speed and rhythm.
17.Control lever when without air
When the air is cut, this control lever can make the hanging load landed safely.
