A [handwheel](https://zimm.com/product/handwheel-hr/) allows manual operation of the screw jack – for example during commissioning, maintenance, or emergency operation. It is connected directly to the worm gear or via a coupling.

- Manual linear motion
- Simple operation without a motor
- Ideal for emergency use
