A frame is pivotally connected to a chassis at a location near a first end of the frame. A jack is disposed between the chassis and the frame to enable pivoting movement of the frame relative to the chassis. A pulley is connected to the frame at a location near a second end of the frame that is opposite the first end of the frame. A winch is disposed on the frame to enable pulling of wire over the pulley. A control device enables control of the jack so as to enable positioning of the pulley that is connected to the frame.
