Turns heavy labor into light work!

PowerArm Series of assistive devices

Pneumatically assists motion from the side or from below.
It can comfortably carry heavy objects even in narrow places such as inside machine tools.

If you have this problem

  • Problem 01
    Reduce the load on the body when replacing jigs and workpieces on machine tools!
  • Problem 02
    When using assistive devices even in places where space is limited!
  • Problem 03
    When considering the ideal transport method for each workpiece!

The PowerArm Assistive Device

What is the PowerArm Assistive Device?

It is a new type of balancer (weight assisting component) that assists motion from the side or from below using compressed air. Automatically balances according to the detected weight.

For changing workpieces and jigs on machine tools

Machine tools have ceilings, making it difficult to use assistive devices from above. However, the PowerArm assists motion from below, making it easy to replace workpieces and jigs inside machine tools.

Case study

Range of Motion and Stowability

It supports a wide range of movement, up to 2.6m long and 2.3m horizontal. It can be compactly stored within 1 m square when not in use.

Basic Features of PowerArm

Controls and attachments tailored to the workpiece

Attachments and control can be made according to the workpiece. Dollies and control boxes, etc., can be prepared according to your work and workpieces.

For solving the following problems with machine tools

Setting the workpiece on the Machine Tool

Even in cases where there is a ceiling that prevents the use of an assist device or other device from the top, the PowerArm can approach from the side, reducing the need to work in an unreasonable position. Pipe-shaped workpieces can be safely transported by clamping with an air hand.
