SAN-EI Air Balancer
Pneumatic Load Balancer System
The SAN-EI Air Balancer, branded as “MY HAND”, is a pneumatic lifting and balancing device powered by compressed air. It is designed to allow operators to lift, lower, and move heavy loads smoothly with minimal effort, effectively acting as a “right hand” for material handling operations.
Unlike conventional lifting equipment, the air balancer automatically adjusts the lifting force according to the weight of the load, enabling safe and precise handling of heavy objects in industrial environments.
1 Main Features
Labor-Saving Operation
The air balancer allows heavy objects to be moved easily using only one hand, greatly reducing operator fatigue and improving working efficiency.
Automatic Load Detection
A built-in load detection system senses the weight of the workpiece and automatically adjusts the air pressure to balance the load.
Simple Weight Measurement
A simple scale integrated into the balancer enables operators to estimate the approximate weight of the object being lifted.
All-Air Powered System
All operations are driven purely by compressed air, eliminating electrical sparks and making the equipment safe for explosive or hazardous environments.
Simple and Lightweight Design
The mechanical structure is simple and compact, resulting in a lightweight system that is easy to install and maintain.
2 Working Principle
The air balancer operates based on a pneumatic balancing mechanism.
Operating process
-
A workpiece is attached to the hook of the balancer.
-
When the operator lifts the object, a load detector senses the weight.
-
The detector sends a pressure signal corresponding to the load weight.
-
The air cylinder generates an upward pulling force equal to the weight of the load.
-
The load becomes balanced, allowing the operator to move it freely in vertical or horizontal directions.
Because the lifting force continuously adjusts to the load weight, the object can be manipulated smoothly and safely.
3 Operating Conditions
Typical operating parameters include:
Air supply pressure:
0.3 – 0.6 MPa
Installation location:
Indoor use recommended
Installation time:
Most air balancer systems can be installed within one day, depending on the configuration.
4 Typical Models
SAN-EI provides different air balancer models depending on the required load capacity.
Example Models
BTA80A-S
BTA120A-W
BTA Series (various capacities)

These models vary in:
-
maximum suspension load
-
lifting stroke
-
air consumption
-
mounting configuration.
The exact specifications depend on the model and application.
