he illustration on the right shows how the Ergolift MA manipulator works. It is usually mounted on a floor pillar and can be rotated manually around the pillar (theta axis). The controls and the gripper are integrated as one unit, which can be manually moved horizontally (x axis) or hydraulically lifted (z axis).

All gripping tools can be rotated around their attachment (alpha axis). The drive is a silent hydraulic system powered by a three phase motor. The vertical movement is powered both upwards and downwards. In case of power failure, a broken oil tube or any other breakdown the load is locked in place by a safety valve. The arm system is a four bar mechanism with low friction, which always holds the tool attachment horizontal regardless of the arm position.

Controlling it is easy. You use either a thumb wheel, up/down buttons or our classic lifting handle. The lifting handle allows the operator to set the lifting speed continuously, if the handle is released it returns to neutral immediately and the machine stops in position.
