Abstract: A hydraulic winch assembly uses a control algorithm that separates brake control from drum rotation to permit fine control of load position. Actuation of an operator interface to a first position displacement threshold will release a drum brake but will not activate a hydraulic pump for operating a hydraulic motor coupled to the drum until the operator interface is moved to a second position displacement threshold. During the operating condition when the brake is released but the pump is not operating, the force of a load applied to a cable coupled to the drum may cause the cable to slowly unwind from and rotate the drum, thereby permitting fine control of drum rotation. Additionally, when the pump is activated upon further movement of the operator interface, a speed of the motor may be modulated, such as by a gear ratio command, to permit precise control over lower drum speeds.

Abstract: A track installation system for a machine is provided. The track installation system includes an operator interface. The operator interface is configured to provide a signal indicative of an installation of a first track over a first sprocket, and a signal indicative of at least one of a direction and a speed of rotation of the first sprocket. The track installation system also includes a controller configured to receive the signal indicative of the installation of the first track over the first sprocket. The controller is also configured to receive the signal indicative of at least one of the direction and the speed of rotation of the first sprocket. The controller is further configured to control at least a parameter of the machine to hold at least one of the machine, the first sprocket, and the second sprocket in a stationary state.
