Pneumatic balancers achieve "gravity free" control of loads through compressed air, and their operating rules and safety regulations must strictly follow the following process:

1、 Core operating rules

Pre startup inspection

Gas source confirmation: Ensure that the pressure of the gas source is stable at 4-6 Bar, and check if there is any air leakage at the connection of the gas pipe.

Load matching: Verify that the load weight is within the rated range (such as within 300 kg), and overloading is prohibited.

Safety verification: Test the emergency stop button and safety valve functions to confirm that there are no abnormalities.

Load control process

Suspension mode: When the control valve is pressed, the load enters a weightless state and can be freely moved to the designated position by hand.

Lift control: Adjust the air pressure through buttons or handles to achieve precise lifting or lowering of the load.

Speed regulation: Utilizing a control valve for stepless speed regulation, the high-speed mode can reach up to 100 mm/s, adapting to different work rhythms.

Emergency situation handling

Gas outage protection: In case of sudden gas outage, the pressure holding gas of the miniature gas storage tank supports a slow decrease in load, and personnel are strictly prohibited from standing below.

Fault response: Immediately press the emergency stop button to cut off the gas source and evacuate surrounding personnel.

2、 Safety operation standards

Personnel qualifications

Operators need to undergo professional training to master equipment principles and emergency response procedures.

Unauthorized personnel are prohibited from operating the equipment.

Environmental adaptation

Explosion proof scenario: Choose explosion-proof equipment that meets ATEX certification to avoid sparks.

Special environment: When used in damp, dust-free, or high-temperature areas, additional protective devices need to be installed.

maintenance plan

Daily inspection: Clean the air source interface daily, remove accumulated water and impurities, and prevent blockage.

Regular maintenance: Check the seals and pressure sensors monthly, replace the filters every six months to ensure the quality of the air source.

Fault repair: Repair shall be carried out by professional technicians, and unauthorized disassembly or modification of equipment is prohibited.

3、 Load Handling Guide

Capture and Release

Fixture matching: Select tools such as vacuum suction cups and magnetic fixtures based on load characteristics to ensure firm fixation.

Release preparation: Before descending, check the area below to ensure there are no personnel or obstacles.

Special load handling

Asymmetric load: Use double hooks or balanced brackets to prevent tilting.

Fragile items: Reduce the operating speed to low speed mode to avoid impact.

Prohibited Acts

Overloading or lateral dragging of loads is prohibited to prevent equipment damage.

It is prohibited to adjust the air pressure parameters during device operation to avoid loss of control.

4、 Technical details and compliance requirements

Air source quality: Compressed air needs to be filtered to a precision of 5 μ m, with an oil content not exceeding 5 mg/m ³, to prevent equipment contamination.

Installation standard: The suspension device must comply with ISO specifications to ensure no shaking and enhance stability.

Security certification: The device must pass Performance Level d security certification, comply with EN ISO 13849-1 standard, and ensure functional safety.
