Product Description
GTB Type Air Balancer
Product Introduction:
An air balancer is a pneumatic assisted material handling device. It uses compressed air as its power source and, through a transmission mechanism, balances the load's own weight against the air pressure within the cylinder to achieve lifting and lowering motions.
Advantages of Air Balancer over Electric Chain Hoists:
*Faster lifting and lowering speeds — typically 2 to 6 times faster than electric hoists
*Features a "floating" function for effortless and precise load positioning
*Capable of continuous 24/7 operation with extremely high duty cycle
*Powered by compressed air with spark-free operation for enhanced safety
*Utilizes screw drive transmission for smooth, jolt-free lifting and lowering, with infinitely variable speed control

| Notes: 1.The actual lifting capacity is primarily determined by the input air pressure. For every 0.1 MPa decrease in input pressure, the actual lifting capacity will be reduced by 10%. 2.The recommended maximum lifting weight is approximately 90% of the rated load. 3.For special requirements, please contact us. | ||||||

Air Balancer Performance Features:
1.Safety — Powered by compressed air with spark-free operation.
*Equipped with air-cutoff protection to prevent load dropping even in the event of sudden air supply interruption.
*Features overload protection — cannot lift loads exceeding rated capacity.
Built-in centrifugal braking function prevents sudden rapid upward movement caused by improper operation.
2.High Efficiency — Fast lifting and lowering speeds, up to 1 m/s.
Infinitely variable speed control allows free adjustment of lifting speed according to the load weight.
3.Precision — Self-adaptive "floating" function creates a "weightless" state when lifting components, enabling effortless and precise load positioning for power-assisted assembly.
4.Energy Saving — Extremely low air consumption, approximately 0.21 m³/h per working cycle on average — only 1/50 of the air consumption of a pneumatic hoist.
Clean, oil-free operation with only pre-lubricated internal components required for long-term use.Compact size and low noise.
