Product Introduction

3 ton Trolley Type pneumatic Air Chain Hoist can be driven only by supplying a certain pressure of compressed air, achieving low energy consumption and high efficiency.

It also has the function of gas-cut protection, which ensures that the work piece does not fall or fall in the case of sudden gas-cut.

It has long been widely used in industrialized countries. Its working principle is to convert the pressure energy of compressed air into mechanical energy to achieve the purpose of lifting goods. It has the incomparable advantages of electric hoists.

3. Gas distribution system

The lifting mechanism includes air motor, planetary reducer, and hanging assembly, brake, lifting chain, hook assembly and main control valve. The lifting mechanism controls the main control valve to realize the lifting and lowering of the lifting heavy object, and realizes the lifting and lowering positioning braking by opening and closing the brake.

The 3 ton Trolley Type pneumatic Air Chain Hoist ensures the safety of the lifting operation. The whole lifting mechanism of the pneumatic hoist can be used fixedly or moved under the traveling mechanism.

3 ton Trolley Type pneumatic Air Chain Hoist traveling mechanism adopts a pneumatic traveling trolley, which is composed of active wheels, passive wheels, and wall panels. The main control valve controls the pneumatic motor and the planetary reducer drives the active wheels to travel to realize the horizontal movement of the hoisting weight.

The gas distribution system uses compressed air as the power source to control the lifting and running of the pneumatic hoist. Eliminates the end user's troubles caused by lifting or falling off.

4. Applicable Environment:

3 ton Trolley Type pneumatic Air Chain Hoists are widely used in chemical plants, textiles, spraying, freight logistics, ports, mining and mining and other workplaces with flammable, explosive, high temperature, high smoke and dust, and strong corrosion.

It has the characteristics of high frequency and infinitely variable speed, and is favored by processing and manufacturing enterprises and logistics enterprises such as trolleys, large tractors, electric motors, household refrigerators, etc. with large production volume and strong continuous work.

Especially in some industrial production: crude oil, chemical plants, trolleys, mining and other flammable and explosive places, the pneumatic hoist must be mandatory.

5. Safe Operation Specifications:

(1) Rigorously improve the load that is greater than the product's ability to improve.

(2) When lifting heavy objects, it is strictly forbidden to stand under the lifting objects.

(3) Strictly use the load chain as a hanging chain.

(4) If the sling is twisted, kinked or damaged, it is forbidden to use the pneumatic hoist.

(5) It is not allowed to hang objects with load for too long.

(6) The load chain is not allowed to be grounded by welding, and it is not allowed to weld on the pneumatic hoist or hanging chain.

(7) It is not allowed to use the upper and lower stopper to brake the pneumatic hoist.

(8) Side pulling or side dragging is not allowed.

(9) It is forbidden to insert bolts or connect by other methods between the slings.

(10) Check the wear or damage of the pneumatic hoist and the brake or limit device before each shift.

(11) Periodically and thoroughly inspect the pneumatic hoist and replace worn or damaged parts.

(12) Lubricate and maintain the equipment as required.

(13) make sure that the air source is closed during the maintenance of the pneumatic hoist.

(14) 3 ton Trolley Type pneumatic Air Chain Hoist users should be trained on safety and use.

6. How to operate?

The operation mode of the air hoist is different from that of the electric hoist. The operation mode of the air hoist is generally only the handle. If you have special requirements, please contact us for clarification.

7. Transportation:

Compared with the electric hoist (electric wire rope hoist and electric chain hoist), the air hoist is lighter in weight, and it is applicable to three modes of transportation: air, sea and land. If the customer's demand is urgent, we suggest that the customer directly transportation.
