When selecting, operating, and maintaining pneumatic winches, multiple factors need to be considered comprehensively to ensure their efficient and safe operation. The following is a detailed explanation of key precautions:

1、 Technical parameter matching

Lifting Capacity

Confirm whether the rated tension or lifting force of the pneumatic winch meets the actual working conditions, and leave a safety margin (recommended safety factor ≥ 1.5).

Example: If you need to increase the load by 5 tons, you should choose a model with a rated load of ≥ 7.5 tons.

Speed&Rope Capacity

Select the appropriate drum speed and rope capacity based on the frequency and distance requirements of the homework.

Example: High frequency short distance operations can choose high-speed models; Long distance operations require large rope capacity drums.

Air Supply Requirements

Verify the required compressed air pressure (usually 0.5-0.9 MPa) and flow rate to ensure compatibility with the existing air source system.

Example: If the winch requires a pressure of 0.7 MPa and the air source can only provide 0.5 MPa, the air source equipment needs to be upgraded.

2、 Environmental adaptability

Hazardous Area Certification

In flammable and explosive environments, explosion-proof models certified by ATEX, IECEx, etc. must be selected.

Example: Explosion proof winches that comply with GB 3836 standards are required for underground operations in coal mines.

Environmental Protection Rating (IP Rating)

Choose the protection level according to the usage environment, such as IP54 (dustproof and waterproof) for outdoor use, and IP66 (higher protection) for high humidity or corrosive environments.

Operating Temperature&Humidity Range

Confirm that the equipment can operate normally under extreme temperatures such as -20 ° C to+60 ° C, and the humidity tolerance range should be in line with the actual environment.

3、 Safety and operational standards

Safety Features

Ensure that the equipment is equipped with emergency stop buttons, overload protection devices, and limit switches, and regularly test their effectiveness.

Operator Training

Operators need to receive professional training, familiarize themselves with equipment performance, operating procedures, and emergency response measures.

Regular Maintenance Schedule

Develop a regular inspection plan, including lubrication, fastener inspection, brake system testing, etc., and record maintenance logs.

4、 Installation and Debugging

Foundation fixed

Ensure that the winch is installed on a stable foundation, avoiding vibration or displacement, and following the manufacturer's installation guidelines.

Air Line Connection

Use air pipes and fittings that meet the pressure rating, ensure no leaks, and install air filters and pressure reducing valves.

Load Testing

After installation, conduct no-load and load tests to verify whether the equipment performance meets the standards and adjust it to the optimal state.
