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.

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.

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.

Setting Pipe-shaped Workpieces on the Washer
Pipe-shaped workpieces can be safely transported by clamping with an air hand.

Changing jig setups on a vertical machining center
Jig replacement, which was done with two workers, can now be done by one person, contributing to labor saving.

Setting a round bar-shaped workpiece on a lathe
Round bar-shaped workpieces are difficult to grip, and there is a risk of injury if they are accidentally dropped, the PowerArm enables safe workpiece settings.

Attaching and detaching grinding wheels to and from grinding machines
Enables work with an unreasonable posture to be performed in a safe position, thereby preventing back pain. Also, a dolly can be used for conveyance between processes.

Assembly assistance for machine tools
Working with a hoist can be difficult to move smoothly, but the PowerArm can be clamped directly with a dedicated attachment, helping to reduce work time.
