To avoid tiring manual operations a small power pack and hydraulic motor , with the help of a proportional control valve, can mechanically rotate organs which were earlier rotated manually. When automobiles need to be loaded on upper decks of a transport truck, the power pack proves helpful in lowering the deck for easy loading. Operation is simple. The tool spindle needs to be inserted in the organ to activate the control valve. This will help rapid rotation and results in the movement of heavy items with minimum effort. Speed is controlled through a tool control valve. This easy rotation is achieved by the adjustable arm which also ensures safe operation.
