When using pneumatic balancers, the following key points should be noted to ensure safe operation, efficient equipment operation, and extended service life:

1、 Pre operation inspection

Equipment integrity check

Check the appearance of the pneumatic balancer for cracks, deformation, or wear to ensure there is no risk of air leakage.

Confirm that suspension components such as hooks, chains, or straps are not broken, corroded, or overloaded.

Example: If cracks are found on the hook, it should be replaced immediately to avoid accidents caused by breakage during lifting.

Air source system inspection

Ensure that the compressed air pressure meets the equipment requirements (usually 0.4-0.6 MPa), as insufficient pressure can cause the balancer to malfunction.

Check if the tracheal connection is secure, free from looseness or aging.

Example: If the tracheal joint is loose, it may cause air leakage or pressure fluctuations, affecting the stability of the balancer.

Environmental safety inspection

Ensure that the operating area is clear of obstacles and avoid collisions during the lifting process.

Check if the ground is flat to prevent equipment from tilting or tipping over.

Example: When operating in a narrow space, it is necessary to clean up debris in advance to ensure a smooth lifting path.

2、 Precautions during operation

load control

Overloading is strictly prohibited to ensure that the load weight is within the rated range of the equipment.

During the lifting process, keep the load stable and avoid sudden acceleration or emergency stop.

Example: If the load exceeds the rated value, it may cause equipment damage or lifting objects to fall.

Operating specifications

Operators need to undergo professional training and be familiar with the equipment operation process.

Before starting, ensure that the surrounding personnel are at a safe distance to avoid accidental injury.

Example: During operation, it is necessary to maintain focus and avoid distractions that may lead to misoperation.

Real time monitoring

Pay close attention to the operation status of the equipment during the operation process. If any abnormal sound or vibration is found, stop the machine immediately for inspection.

Regularly check the pressure gauge to ensure stable pressure.

Example: If the air pressure suddenly drops, it may be due to a leak in the trachea or a malfunction in the air source, and it needs to be promptly investigated.

3、 Post operation maintenance

Equipment cleaning

After the operation is completed, clean the dust and oil stains on the surface of the equipment to prevent corrosion.

Check whether the hook, chain and other components are contaminated with foreign objects and clean them in a timely manner.

Example: If the equipment is exposed to a humid environment for a long time, it is necessary to regularly apply anti rust oil.

Component inspection and replacement

Regularly inspect vulnerable parts such as seals and air pipes, and replace them promptly if wear or aging is found.

Check the wear of suspension components such as hooks and chains, and replace them if necessary.

Example: Aging of seals can cause air leakage, affecting equipment performance and requiring regular replacement.

Record and feedback

Establish equipment maintenance records to document each inspection, repair, and replacement of components.

If any design defects or safety hazards are found in the equipment, promptly report to the manufacturer.

Example: Maintaining records can help track device status and prevent malfunctions in advance.

4、 Safety protection measures

Personal protective equipment

Operators are required to wear safety helmets, gloves, and non slip shoes to avoid accidental injuries.

When working at height, it is necessary to fasten the safety belt.

Example: Wearing gloves can prevent hands from being scratched by lifting objects.

Emergency stop device

Ensure that the equipment is equipped with an emergency stop button and that the operator is familiar with its location and usage.

Regularly test the emergency stop function to ensure its reliability.

Example: In case of danger, pressing the emergency stop button can immediately cut off the gas source and stop the operation of the equipment.

Safety warning signs

Set up clear safety warning signs around the equipment to remind personnel to pay attention to safety.

Example: Set a "no entry" sign in the operation area to prevent unrelated personnel from entering.

5、 Regular maintenance and upkeep

Develop maintenance plan

Develop a detailed maintenance plan based on equipment usage frequency and working environment.

Regularly conduct comprehensive inspections of equipment, including air supply systems, suspension components, and control systems.

Example: High frequency equipment needs to have a shorter maintenance cycle to ensure that the equipment is always in good condition.

Professional maintenance

For complex repairs or replacement of components, it is recommended to have professional technicians perform them.

Regularly lubricate the equipment to reduce wear and tear.

Example: When replacing seals or repairing cylinders, it is necessary to ensure good sealing to avoid air leakage.

Spare parts Management

Reserve commonly used spare parts, such as seals, air pipes, hooks, etc., to ensure timely replacement in case of equipment failure.

Regularly check spare parts inventory and replenish them in a timely manner.

Example: Insufficient spare parts may lead to prolonged equipment downtime and affect production efficiency.

6、 Operator training

Theoretical training

Provide training to operators on equipment principles, operating procedures, and safety precautions.

Ensure that operators understand the performance and limitations of the equipment.

Example: The training content includes the working principle, common faults, and handling methods of the equipment.

Practical training

Under the guidance of professional personnel, conduct practical training and become familiar with the equipment operation process.

Simulate unexpected situations and train operators' emergency response capabilities.

Example: Train operators on how to quickly press the emergency stop button by simulating the falling of lifting objects.

regular assessment

Regularly assess operators to ensure that their operational skills and safety awareness meet the requirements.

Retrain personnel who fail the assessment.

Example: The assessment includes equipment operation, troubleshooting, and emergency response.
