APPARATUS AND METHOD FOR MONITORING A HYDRAULIC PUMP ON A MATERIAL HANDLING VEHICLE

Wear of a pump is estimated using a process that involves operating the pump to drive a hydraulic actuator that moves a member. The actual speed of the member is determined and the speed of the pump is sensed. Pressure of fluid conveyed from the pump to the hydraulic actuator also is sensed. A predi...
