The structure of the manned pneumatic winch is usually composed of a capstan, wire rope, guide rail, cockpit, and so on.
① The capstan is the core part of the whole winch device, which realizes the lifting of heavy objects by controlling the rotation of the capstan and the retraction of the wire rope.
② The wire rope carries the weight of the heavy object and is transported by the power of the capstan.
③ The guide rail is mainly used to limit the movement trajectory of the wire rope to ensure the stability and safety of the manned air winch during work.
④ The cockpit is the area where people enter the pneumatic winch for operation and control, which provides a safe environment for personnel protection and convenient operation.
As a common lifting and traction equipment in modern industrial production processes, manned air winches are widely used in mines, ports, construction, logistics, factories, and other fields. In different industries, the use of manned winches is different.
In the construction industry, manned winches are often used in the construction of high-rise buildings. Through the manned winch, workers can directly enter the outer wall of the building for demolition, repair, maintenance, and other work.
In the mining industry, manned pneumatic winches are often used for underground operations in coal mines. Workers can safely enter the mine to carry out maintenance and repair work on mining equipment.
In the logistics industry, the manned air winch can be used for the handling loading, and unloading of heavy objects. Workers can sit in the manned winch to lift the goods from a high place or a narrow space to the required position.
In addition to its use in various industries, the manned winch can also be used in rescue work in emergencies. When emergency situations such as earthquakes, landslides, and accidents occur, rescuers can use manned winches to enter difficult terrain or high places to carry out search and rescue work to improve the efficiency and safety of rescue.
Safety is always an important consideration when using a manned winch. The staff need to receive professional training and guidance and strictly abide by the operating procedures during use. The stability and structural safety of the manned winch must be guaranteed to prevent accidents. Get professional guidance online.

Manned Pneumatic Air Winch working principle:
The electric manned winch is the prime mover of compressed air as the working medium. It is a power device that converts pressure energy into mechanical energy by using the expansion of compressed air.
The air motor and gearbox are its main power components. The operation principle of the air motor is basically similar to that of the internal combustion engine. Air expansion propels the piston into reciprocating motion, which is then converted to circular motion by a crank link.
The gearbox is connected to the air motor and contains two sets of gears, which transmit the circular kinetic energy of the air motor to the drum to make it rotate.
Manned Pneumatic Air Winch Features:
Double design factor; An 8:1 design factor is used for carrying people; a 5:1 design factor is used for carrying objects; the minimum ratio of drum diameter to cable diameter is 18:1, which prevents cable wear.
1. The manned air winch adopts a drum double support structure, and the wire rope end is fixed in a safe and reliable form.
2. The manned pneumatic winch deceleration system adopts (drum) built-in planetary deceleration mechanism.
3. The brake system of the manned pneumatic winch adopts two types of brakes: a built-in full-disc air-cut brake and an external hand brake. The sealed automatic full-disc brake can resist the erosion of salt spray, dust, or moisture, and the manual roller installation with belt type brake, the operator can apply the brake.
4. The manned air winch can realize two control forms local operation and remote control operation. Both control forms must have multiple safety protection measures such as loose rope protection, overload protection, and limit protection, emergency stop protection, air cut-off brake, and safety release:
① Loose rope protection: When the person or object to be hoisted touches the support surface, the system will automatically stop the lowering of the sling after the sling continues to descend for a small distance, so as not to injure the person or object.
② Overload protection: When the load exceeds the rated load or the set load, the winch will not be able to overload.
③ Limit protection: The control system is equipped with an upper and lower limit device, when the manned air winch lifts or exceeds the set upper and lower position, the manned pneumatic winch will stop running to avoid injury.
④ Emergency stop protection: When the operation is out of control or encounters other emergency situations, you can quickly press the "stop button" to interrupt the air supply to avoid accidents. After the "stop button" is pressed, it has a self-locking function, and the air supply cannot be restored even if it accidentally pops up. Only after the "start button" is pressed can the normal air supply be restored.
⑤ Air cut-off brake (built-in wet air cut-off brake): When the air supply system is interrupted due to a pipeline burst or other reasons, the winch will automatically brake to avoid personal injury or other losses.
⑥ Safety release function: That is, when the winch stops working unexpectedly, it should be able to lower the person or object carried to a safe position.
How to Use the Manned Pneumatic Winch?
1. Start the motor first, and then the transmission gear starts to run. Before starting, the brake belt on the drum should be braked first, and the brake handle on the big gear should be loosened, so that the drum does not rotate, and only the big inner gear turns.
2. If you want to start the drum, you must first completely loosen the brake belt on the drum, and then tighten the brake belt on the large internal gear. At this time, the drum turns and winds the wire rope to work.
3. During the working process of the electric manned winch, if you want to suspend the operation of the pneumatic winch, you can loosen the brake band of the large internal gear, and then tighten the brake band on the reel.
4. When starting the motor, the two brakes cannot brake at the same time, otherwise it will easily cause the motor to burn out. The temperature of the reel, brake band, and bearing of the electric manned winch must not exceed 70°C. If the temperature rises sharply, stop the machine immediately for inspection.
Manned Pneumatic Air Winch Operation Precautions
1. The manned pneumatic air winch should not be overloaded.
2. The operation of the manned pneumatic air winch should be stable, and the hooks, hanging objects, and slings should be seen visually, and other objects should not be hung or stuck. Keep in sight contact at all times. When direct visual inspection is not possible, special personnel must be directed.
3. When lifting, the steel wire ropes on the drum should be arranged neatly. When the hanging object is still, the winch operator's hands and feet cannot leave the brakes.
4. When the manned pneumatic air winch is stopped or repaired, the safety warning sign should be hung and the power source should be cut off.
5. When the manned pneumatic air winch is out of service, the air source should be cut off and braked.
