Abstract: A unique, single lever hand control is operatively associated with means for energizing the clutch mechanism which control the various parts of the transmission as well as control the reversibility and stroke of a pump which drives the input motor. The hand control assures a proper correlation between braking and powering of the drum.

Abstract: A winch transmission and control which through selective energization of separate parts of the transmission enables the winch to automatically change to a different output speed, produce a fully braked condition, or a freewheeling condition. Reversing of the direction of the drum occurs through reversing the direction of the power input motor to the transmission. A unique, single lever hand control is operatively associated with means for energizing the clutch mechanisms which control the various parts of the transmission as well as control the reversibility and stroke of a pump which drives the input motor. The hand control assures a proper correlation between braking and powering of the drum. Another unique feature is a combination cable guide and external structural tie bar for a hollow drum of a towing winch used on a towing vehicle for strengthening the winch drum case. Another unique feature is a technique for installing large, slow-speed ball bearings in a bearing race.
