When using a pneumatic balancer, it is necessary to strictly follow the operating specifications and safety requirements to ensure efficient operation of the equipment and avoid accidents. The following is a summary and explanation of key precautions:

1、 Pre operation inspection

Equipment integrity check

Appearance inspection: Confirm that there are no cracks, deformations, or wear on components such as cylinders, hooks, and control handles.

Tightening of connectors: Check if bolts, pins, etc. are loose to prevent component detachment.

Example: If the hook cracks, it should be replaced immediately to avoid breakage during lifting.

Air source and pipeline inspection

Pressure stability: Ensure that the gas supply pressure meets the equipment requirements (such as 6-8 bar), as pressure fluctuations may cause load shaking.

Pipeline sealing: Check if there is any air leakage at the trachea joint to avoid load loss due to insufficient air pressure.

Data reference: When the air pressure is below 5 bar, the load lifting speed of a certain model of balancer decreases by 30%.

Load matching

Load weight confirmation: The load must be within the rated range of the balancer (such as 5-50 kg), overloading may cause equipment damage or fall.

Load center of gravity calibration: Ensure that the load center of gravity is aligned with the suspension point of the balancer, avoiding tilting or swinging.

Case: When lifting eccentric loads, it is necessary to adjust the lifting equipment or use auxiliary balancing devices.

2、 Operating standards

Smooth operation

Slow lifting: Avoid rapid operation that may cause the load to shake or impact.

Fine tuning control: Utilize the fine tuning function of the balancer (such as ± 0.1 kg accuracy) to accurately locate the load.

Comparison: Traditional manual lifting requires 10 seconds for positioning, while high-precision balancers only require 3 seconds.

Prohibited from using beyond the scope

Height limit: Avoid collisions with the ceiling or floor with the load, and reserve a safe distance (such as ≥ 0.5 m).

Angle limitation: Some balancers limit the tilt angle (such as ≤ 15 °), and exceeding the limit may trigger a safety lock.

Risk: Exceeding the scope of use may result in equipment overload or structural damage.

Precautions for Multi person Collaboration

Unified command: When multiple people are operating, a designated commander should be appointed to avoid signal confusion.

Communication confirmation: Use gestures or walkie talkies to clearly indicate operating instructions (such as "up" or "stop").

Example: In a car assembly line, two workers need to operate the balancer synchronously to install the engine.

3、 Security protection

Personal Protective Equipment (PPE)

Must wear equipment: safety helmet, anti slip shoes, protective gloves.

Optional equipment: goggles (splash proof), earplugs (for high noise environments).

Regulatory basis: OSHA standards require that safety helmets must be worn during lifting operations.

Security Zone Settings

Isolation danger zone: Set up warning signs below the load to prohibit personnel from entering.

Anti collision measures: Install buffer pads on columns or walls to reduce collision damage.

Data: After setting up isolation zones, the accident rate decreased by 60%.

Emergency Management

Emergency stop: Familiarize yourself with the location of the emergency stop button and press it immediately in case of danger.

Load fixation: If the balancer fails, temporarily fix the load with ropes or fixtures.

Evacuation route: Keep the operating area clear for quick evacuation.

4、 Maintenance and upkeep

Routine maintenance

Cleaning: Remove dust and oil stains from the cylinder and guide rail to prevent sticking.

Lubrication: Regularly add lubricating grease to moving parts such as bearings and pulleys.

Frequency: Daily cleaning, weekly lubrication.

Regular inspection

Monthly inspection: Test the functions of safety valves and limit switches, and inspect the aging of the trachea.

Annual maintenance: Professional personnel disassemble and inspect internal parts for wear and replace seals.

Record: Establish and maintain a ledger to record inspection time, content, and replacement parts.

Fault handling

Common faults: insufficient air pressure, load drift, abnormal noise.

Troubleshooting steps:

Check the air source pressure and pipeline.

Calibrate the load sensor.

Replace worn sealing rings or bearings.

Example: When the load drifts, it may be due to cylinder leakage and the seal needs to be replaced.

5、 Training and Qualification

Operation training

Theoretical learning: Master equipment principles, operating procedures, and safety knowledge.

Practical training: Complete exercises such as load lifting and fault simulation under guidance.

Assessment criteria: passing theoretical exams (≥ 80 points) and practical evaluations.

Qualification requirements

Certification for employment: Some industries (such as aviation and nuclear power) require operators to hold a special equipment operation certificate.

Certificate validity period: usually 3-5 years, requiring regular review.

Regulations: According to the Special Equipment Safety Law, operating without a license may result in fines.

6、 Environment and Compliance

Environmental adaptability

Temperature limit: Avoid using in environments below -10 ° C or above 50 ° C to prevent seal aging.

Dustproof and Waterproof: In dusty or humid environments, select equipment with a protection level of ≥ IP54.

Case: A factory experienced water ingress inside the balancer due to lack of protection, resulting in an increase of 20000 yuan in maintenance costs.

Compliance requirements

Standard compliance: Complies with ISO 4414 (Safety of Pneumatic Systems) and GB/T 3811 (Design Specification for Cranes).

Certification requirements: Priority should be given to products that have passed CE and UL certification.

Inspection: Regularly undergo third-party security audits to ensure compliance.
