رافعة هوائية محمية ضد الانفجار رافعات هوائية HQ هوائية

Pneumatic hoist product introduction:

Pneumatic hoist is mainly used in petroleum, chemical, coal mine and other special environment of high explosive dust, explosion-proof have grade requirements. Pneumatic hoist is the ideal explosion-proof lifting equipment, is an upgraded product of electric hoist, the load range from 250 kg to 30 tonnes depending on the model. Pneumatic hoists can be driven only by compressed air at a certain pressure. It also has the function of air break protection, which ensures that the workpiece will not fall down and drop in case of sudden air break. With a variety of non-standard fixtures, pneumatic hoists can lift workpieces of various shapes. The installation form can be matched with cantilever crane or guide rail to achieve movement. Commonly used pneumatic hoists are vane type, piston type and cylinder type. Used in petroleum, chemical, coal mining, textile, warehousing, household appliances production line, automobile manufacturing line and ship repair and other industries, is the enterprise safety production, down indispensable equipment. Pneumatic hoist is compressed air as the driving force to promote the rotation of the pneumatic motor, the variable speed (deceleration) to increase the torque to complete the lifting work.

HQ pneumatic hoist series pneumatic hoist load 1000kg ~ 5000kg, small size, light weight, no sparks and electric shock, easy to use and safe.
1 Pneumatic hoist is the ideal lifting equipment in the world. In the developed industry has long been used. It has electric hoist incomparable advantages:
a, steam, high dust resistance.
b Small size, lightweight, weight for the electric hoist 1 / 3 ~ 1 / 8.

Pneumatic hoist product composition:

1. Hand-operated valve: mainly consists of: handle, valve body and key composition. Manipulate the key to open the valve to control the main control valve airway and motor airway connection. Or hand-pulled rope operation
   Pull the pendulum rotation to achieve the valve opening, can achieve stepless variable speed.
2. Main control valve: It mainly consists of: left and right valve stems, connecting rod and air distribution disc. Through the switching of the left and right airways to complete the air motor forward and reverse air distribution work.
3. Air motor: mainly consists of: rotor, stator, front and rear end caps and blades. When the air distribution disc of the main control valve sends compressed air into the motor, the blades rotate with the rotor at a high speed.
4. Hanging: mainly consists of: upper hook, hanging body, sprocket, chain, lower hook and other parts. Relying on the sprocket’s forward and reverse rotation to complete the upward and downward movement.
5. Reducer: mainly composed of: shell and a set of planetary reduction mechanism. When the high-speed shaft of the air motor is input into the reduction mechanism, the torque is increased by deceleration and output to the lifting sprocket by the final stage.
6. Brake mechanism: mainly composed of brake cone, brake ring and cylinder. The brake cone and brake ring are separated through the main control valve to the cylinder to release the brake.
7. Interlocking mechanism: mainly composed of: rotating shaft, pendulum frame and reset spring. It plays the role of anti-collision and protection when it rises and falls to the position.
