3. Component:

(1) Manual valve: mainly composed of handle, valve body and buttons. Manipulating the button can open the valve to control the communication between the air passage of the main control valve and the air passage of the motor. Or pull the rotation of the pendulum rod to achieve the valve opening, which can realize stepless speed change.

(2) Main control valve: It is mainly composed of left and right valve stems, connecting rods and gas distribution plates. Through the switching of the left and right air passages, the gas distribution work of the forward and reverse rotation of the air motor is completed.

(3) Air motor: It is mainly composed of rotor, stator, front and rear end covers and blades. When the air distribution plate of the main control valve sends the compressed air into the motor, the blades rotate with the rotor at high speed.

(4) Hanging: It is mainly composed of upper hook, hanging body, sprocket, chain, lower hook and other parts. Relying on the forward and reverse rotation of the sprocket to complete the upward and downward movement.

(5) Reducer: It is mainly composed of a casing and a set of planetary reduction mechanisms. When the high-speed shaft of the air motor is input to the deceleration mechanism, the torque increases after deceleration, and is output to the lifting sprocket from the final stage.

(6) Brake mechanism: It is mainly composed of brake cone, brake ring and cylinder block. The air is distributed to the cylinder through the main control valve, and the brake cone and the brake ring are separated to release the brake.

(7) Interlocking mechanism: It is mainly composed of a rotating shaft, a swing frame and a return spring. Anti-collision and protection when ascending and descending to position.

4. The difference between pneumatic hoist and electric hoist:

Contents	Pneumatic hoist	Electric hoist
Power	0.6Mpa compressed air	220V-440V voltage
running speed	Adjustable and fast (4 times that of electric)	Not adjustable, slow speed
Safety	No sparks and electric shock	Electric leakage, sparks, easy electric shock
structure	Air motors are simpler and smaller	Electric motors are bulky, heavy, and require many parts to prevent sparks
Pipe routing	No cables required, simple tracheal connection, no professional operation required	Requires professional arrangement, which is more complicated
high temperature work	Can work normally above 60 degrees	Works abnormally at high temperatures
weight	light	heavier
maintain	No professional training required	Professional maintenance required
life	Parts are processed with high precision, so they are suitable for frequent work and long life	Electric motors are inefficient, many components are prone to wear and have relatively short lifespans

5. Advantages

(1) No sparks are generated, which completely solves the explosion-proof problem of lifting equipment. Applicable to: Zone I hazardous locations, including IIC, group T5 and below.

(2) The working system of the small-tonnage pneumatic hoist is 100%, which creates the necessary conditions for high-efficiency continuous operation.

(3) When lifting or descending, the running speed is fast. It is 2 to 3 times that of the electric hoist, and it can sleeplessly adjust the speed.

(4) Acid and alkali resistance, steam resistance and high dust resistance.

(5) It is small and light, and its weight is 1/3 to 1/8 of the electric hoist.

(6) The control operation of the lever is simple, and it can quickly respond to the action command output by the handle when it is lifted or lowered.

(7) The positioning is more accurate, avoiding the problem of inaccurate positioning of ordinary lifting products, and can accurately position the goods to centimeters, achieving zero impact.

(8) Clean and environmentally friendly, safe and reliable, the internal lubrication system eliminates air pollution, and can be used in special or harsh environments such as humidity and high dust.

(9) The handling is labor-saving, the pneumatic hoist is not only beautiful in appearance, but also small in size and quality, and easy to handle. Its solid structure design makes the operation reliable and maintenance less.

(10) Air cut-off protection to avoid the sudden interruption of the air source and the sudden drop of the goods, which improves the safety and reliability during the operation.

1/4 ton 1/2 ton 1 ton 2 ton 10 ton Fixed Type Air Hoist is based on the above advantages that the pneumatic hoist can be widely used in petroleum, chemical, coal mine, textile, machinery production, ships, arms and other fields.

6. How to operate?

The operating handle of the pneumatic hoist can be adjusted steplessly when lifting or lowering;

Its running speed is 3 times that of electric hoist and 5-10 times that of chain hoist.

7. Transportation:

The transportation method of air hoist is wider than that of electric hoist. Generally, large-scale lifting equipment is transported by sea or land, but air hoist is relatively light in weight. If it is a sample or the customer has strict time requirements, we The company still recommends air freight to improve transportation efficiency.
