The pneumatic lifting device is designed to make it easier for the operator to overload heavy baskets between individual tubs. The device is manually operated sideways. The operator moves the carrier between positions manually on the bearing path, which minimizes the energy needed to move. In the up and down direction, there are two pneumatic buttons on the arm that activate a pneumatic valve that actuates a pneumatic cylinder. When releasing the button, the position of the lifting device remains unchanged, the load lifting device can be lifted slightly when the pneumatic cylinder is pressurized. An additional non-return valve to the pneumatic circuit is also fitted to the lifting device. On the back of the bath there is a reducing valve on the connected air.
