Crazy Wave

The “Crazy Wave consists of a multi seat bench mounted on bearings which are in turn mounted on two crank arms which rotate in a vertical plane, which is parallel to the vertical plane of the back of the bench. The crank arms are driven by a pair of high torque hydraulic motors via a pinion and spur wheel. The motors are driven in parallel by a single electric motor driving a variable displacement hydraulic pump. This is controlled by means of a joy stick handle mounted on the control panel.
