Abstract
PURPOSE: To provide a control apparatus for controlling operation of winch using a two-speed motor as prime mover, in which a hawser drum and a chain drum are carried on the motor shaft, and they are arranged to be operated selectively and driven at different speeds by shifting the speed mode of said two-speed motor, whereby it is enabled to eliminate mal-functioning of the winch.
CONSTITUTION: Driving shaft 11 is connected to two-speed motor 14, and hawser drum 15 and chain drum 16 respectively combined with clutches 17 and 18 are carried on the driving shaft 11 in side-by-side relationship with each other. When clutch 17 is coupled with drum 15 by shifting clutch lever 20, winch controlling valve is shifted to its operative position and hydraulic oil is supplied to motor 14 from the hydraulic pressure source, whereby motor 14 is rotated in its low-torque mode, thereby driving hawser frum 15 in low-torque, high-speed mode. On the other hand, when clutch lever 20 is turned to couple clutch 18 with chain drum 16 and the winch controlling valve is shifted to its operative position, motor 14 is rotated in its high-torque mode and chain drum 16 is driven in high-torque, low-speed mode.
