The 12K42 ErgoArm plus is a lightweight and versatile mechanical elbow that is compatible with a passive or body-powered hand or terminal device.
Features include:
The internal Infinite Position lock is cable-operated and can be locked, or unlocked, under load in any position. It can bear a load of up to 230N at a forearm length of 305mm.
The Slip-Stop function makes it possible to lower the forearm in a controlled manner without having to fully release and reactivate the lock.
Automatic Forearm Balance (AFB) supports flexion by using energy stored during extension. It promotes a smoother motion when swinging the arm, making it easier to lift the arm. For improved cosmesis, the AFB finger wheel is now the same color as the forearm shell.
A new membrane cover in the crook of the arm protects internal components and prevents user’s clothing from potentially getting trapped, enhancing overall appearance and functionality.
Please see the ErgoArm Family Selection Guide for available sizes and corresponding color options.
