Tips: Why choose ATO air chain hoist?

Air chain hoist is a kind of lifting equipment that uses compressed air as the working medium and converts the pressure energy of the compressed air into mechanical energy to lift the goods. It is mainly composed of five parts: the air motor part, the deceleration mechanism, the air circuit control, the braking mechanism and the lifting mechanism. Widely used in petroleum, chemical, coal mine, textile, warehousing, household appliance production line, automobile manufacturing production line and ship repair and other industries, it is an essential and important equipment for enterprises to produce safely, improve efficiency and reduce costs. Compared with electric chain hoists, pneumatic hoists have the following advantages:

There is no spark, which completely solves the explosion-proof problem of lifting equipment.
It can work in high a temperature, high dust and strong corrosive working environment.
Small size, light weight, easy to install and use.
Continuous high-frequency operation can be realized.
The lifting speed can realize stepless speed change.
Good self-locking performance, safe and reliable.

Compressed air is easy to obtain, and the medium is clean, easy to maintain, and has self-protection properties. In military, textile, chemical and other special industries with flammable, explosive and corrosive media, pneumatic hoists have replaced electric hoists, and their application fields are still expanding. The development of foreign pneumatic hoists is very fast. The pneumatic hoist developed in the United States can lift as small as ton, as large as ton, and the lifting height can reach meters, and the lifting speed is about 100%. Foreign pneumatic hoists first used parallel shaft external gear transmission, and now most of them use planetary transmission.
