Pneumatic hoist is currently the most ideal explosion-proof hoist equipment in the world. Widely used in petroleum, chemical, coal, textile, storage, production line of home appliances, automobile production line and ship building and other industries, it is essential for the enterprise to realize safety manufacturing, efficiency improving, and costs reducing. There are very few manufacturers on this product in local market as high demand of technology, but it’s common in overseas market.
Firstly, pneumatic hoist consists of the following several parts:
1. Pneumatic motor 2. Planetary reduction mechanism 3. Brake mechanism 4 lifting mechanism 5. Pneumatic control parts
Lifting mechanism includes pneumatic motor, planetary gear reducer, hanging assembly, brake, lifting chain, hook assembly and main control valve. Lifting mechanism through the main control valve, is to realize the rise and fall of lifting heavy things, through the open and close brake to realize lifting and falling positioning brake. In order to ensure the safety of pneumatic hoist lifting operation, pneumatic hoist lifting mechanism can be used together as a whole. Mobile used below the travel mechanism, or use with the rail system.
Pneumatic hoist walking mechanism can realize to move heavy objects horizontally by using pneumatic walking car or hand trolley.
The compressed air as power source, distribution system controls pneumatic hoist lifting and traveling by controlling the gas circuit.
Secondly, the working principle of pneumatic hoist:
The compressed air pressure is turned into rotary mechanical energy by pneumatic motor, the output torque drives the planetary reduction operation. the positive and reverse rotation mechanism of pneumatic parts will realize objects lifting.
Thirdly, pneumatic hoist and its advantages
1. The pneumatic hoist can realize stepless speed regulation
Pneumatic hoist stepless speed regulation can achieve the object taking and lifting lightly, accurate positioning and small impact force.
