a skyline logging carriage wherein the winch drum around which the load line is wound is powered by a fluid motor through a worm gear arrangement which eliminates the need for a separate braking system . the fluid motor is driven by a fluid pump powered by a diesel engine mounted on the carriage frame . the hydraulic transmission of power to the winch drum eliminates the need for clutches or direct mechanical connection and braking systems generally required . greater freedom in placement of the winch drum in relation to the fairlead to obtain an optimum fleet angle and distance between the winch drum and fairlead for proper level winding of the load line about the winch drum is made possible by hydraulic transmission of power to the winch drum . operation of the winch line is radio controlled by an operator at a yarder or other location . the carriage is moved along the skyline by a main line or main line and haulback lines .
