GUOMAT Airbag Jack: Air-Powered Lifting

GUOMAT Airbag Jack: Air-Powered Lifting

An airbag jack, also known as a pneumatic jack or air jack, uses compressed air as a power source to inflate a high-strength rubber bladder, thereby lifting heavy objects. Its core component is a rubber bladder. When compressed air (usually from an air pump, compressor, or even automobile exhaust) is injected, the bladder expands vertically upward like a balloon, generating a tremendous lifting force.

1.Core Working Principle: The Power of Air

The operating principle can be summarized as follows: "The pressure of compressed air acts on a large area of ​​the bladder, generating a tremendous upward lifting force."

Power Source: Compressed air is injected through the air inlet.

Actuator: High-pressure air enters and fills the rubber bladder, which is reinforced with multiple layers of fabric and steel wire.

Inflation Lift: The bladder expands rapidly and evenly under the action of air pressure, directly contacting the load tray on top and lifting the load.

Retraction and Retraction: When lowering is required, the air in the airbag is slowly released through a control valve, allowing the load to descend smoothly under its own weight.

The lifting force follows the formula: Lifting Force = Internal Air Pressure × Airbag Effective Area. Therefore, even if the air pressure is not extremely high (typically 5-8 bar), the large effective area of ​​the airbag can easily generate a lifting force of tens or even hundreds of tons.

2. Significant Features and Advantages
Compared to traditional jacks, airbag jacks offer unique and irreplaceable advantages:

High Lifting Force, Light Weight: Because their power is generated by air rather than heavy metal, they are extremely lightweight yet can easily lift loads of tens of tons, resulting in an extremely high power-to-weight ratio.

Extremely Easy Operation: No laborious manual cranking or pumping required; simply connect the air supply and press a switch for a quick and smooth lifting process, significantly saving manpower and time.

Low Contact Surface Requirements: Traditional jacks require a hard, flat surface and a solid contact point. Airbag jacks, on the other hand, only require a relatively flat surface and can even be used on unstable surfaces like sand and mud, thanks to their large contact area with the airbags, which disperses pressure.

Synchronized Lifting and Leveling: Multiple airbag jacks can be connected to a common air source and control valve, enabling simultaneous lifting and precise leveling at multiple points. This is crucial for lifting large equipment, bridges, and buildings.

High Safety: There is no risk of hydraulic fluid leaks, and the lifting process is smooth and impact-free. Furthermore, the rubber airbags themselves provide cushioning and shock absorption.

Portability and Versatility: When deflated, they are compact and easy to carry and store. They have a wide range of applications.
