ABSTRACT OF THE DISCLOSURE A friction winch assembly for securing automobile or other heavy objects to a transporting vehicle includes a spindle rotatably mounted on the transporting vehicle, a ratchet gear axially mounted on said spindle, and an actuator cap for threaded engagement on said spindle. A chain or other elongated means is connected at one of its ends to the spindle for winding or unwinding thereon, and at its other end to the automobile. To wind the chain and secure the vehicle, the actuator cap is rotated with a tool for longitudinal movement along the spindle toward the ratchet until longitudinal movement is limited by a collar affixed to the spindle. The actuator cap, ratchet and spindle eventually frictionally engage each other sufficiently so that they rotate synchronously with the spindle while the chain is wound, until the chain tension secures the automobile. To release the automobile from the friction winch assembly, the actuator cap is rotated in the reverse direction, with a pawl pivotally mounted on the transporting vehicle engaging the ratchet and precluding its rotation. The torque from the chain maintains engagement between the. ratchet and actuator head until the chain is sufficiently unwound, at which time the actuator cap and ratchet disengage.
