Zip Chain Lifter
- Scissor lifter with zip chain mechanism
- An epoch-making lifter that realizes unprecedented high-speed lifting.
- The zip chain lifter is a table type lifter that pushes up the top plate directly with the zip chain.
- Operates 3 to 10 times faster than hydraulic lifters. Supports high-frequency operation, which provides a maximum of 50% energy savings.
What is Zip Chain ?
- High-speed, high-frequency operations
- Multi-point stopping function
- Save overall space
Zip Chain is a chain uniquely developed by Tsubaki. Two chains interlock like a zipper to form a single, strong column for pushing and pulling applications.
Zip Chain Actuator has been developed as a linear actuator products using this chain.
Compared to conventional pneumatic / hydraulic cylinders, this has many features including environmental considerations such as space saving, high-speed / high-frequency operation, multi-point stop function, high stopping accuracy, and free mounting direction. Widely used from small actuators to large lifters.

High speed 2.5x of hydraulic type
Achieves high-speed operation at a maximum lifting speed of 100m/min.
This lifter works through a mechanism that directly pushes up the lift table at a stable speed in proportion to motor rpm, enabling lifting operation at a constant speed. Synchronized operation of multiple lifters is also possible.
Zip Chain Lifter
It maintains a stable speed through the entire stroke range.
Hydraulic type lifters
The speed varies throughout the stroke, as hydraulic lifter moves up and down at a slant to lift the top table.
high-frequency 4.5x of hydraulic type
Unlike with hydraulic lifters, the Zip Chain Lifter does not need to increase the tank capacity of hydraulic units for higher-frequency operation.
In addition, continuous operation with one or more strokes per minute and multi-point stop, which cannot be achieved by hydraulic or other methods, is also possible.
Stopping Precision The hydraulic type is difficult to stop in the middle.
Easily realizes multi-point stopping/multi-level positioning thanks to its simple control structure.
Expected life 10 times more than hydraulic type
The Zip Chain Lifter has a mechanism that directly pushes the lift table, which places a smaller load on the hinges/rollers and enables longer life (over one million strokes).
