The rotatable pulling/pushing load represents a hydraulic cylinder subjected to a load (6), the effective
direction of which (3) can be reversed by rotating it 180°. The weight (3) is held in place by guides and is set
into motion by the cylinder (6). Rubber cushions (1) provide for soft stopping in the end positions.
The locking knob (10) is pulled out in order to rotate the unit. When rotating, grasp one of the two handles
(8) and rotate the unit 180° until the locking knob snaps back into place. Caution: Weight forces may occur
due to eccentricity. The locking knob only snaps into place when the rotating unit is in the vertical position.
The position of the cylinder's piston or the weight can be optionally detected by means of sensors.
Gravitational acceleration acts upon the weight and results in a weight force towards the earth.
