Yes, that's correct. A pneumatic winch does not require electricity to operate. Instead of relying on an electric motor, a pneumatic winch uses compressed air as its power source. The winch converts the energy stored in the compressed air into mechanical power to perform lifting or pulling tasks.

Here's how a pneumatic winch generally operates:

Compressed Air Source:

The pneumatic winch is connected to a compressed air source, typically provided by an air compressor.

Air Motor:

The winch is equipped with an air motor, which is powered by the compressed air. The air motor converts the energy from the expanding air into mechanical power.

Mechanical Power Transmission:

The mechanical power generated by the air motor is then transmitted to the winch's drum or gear mechanism. This mechanism is responsible for winding and unwinding the cable or rope.

Lifting or Pulling:

As the air motor operates, the winch lifts or pulls the load by winding the cable or rope around the drum. The operator can control the winching operation using a control valve that regulates the airflow to the air motor.

Braking System:

Pneumatic winches typically incorporate a braking system to control and secure the load during lifting or pulling operations.

One of the advantages of pneumatic winches is their independence from electrical power sources. This makes them suitable for use in environments where electricity is not readily available, or in applications where electrical equipment may not be safe or practical. Pneumatic winches are commonly used in industries such as marine, offshore, mining, and construction, where the availability of compressed air is more convenient or preferable than electrical power
