The BOLTON DOUBLE OR SINGLE DRUM is an hydraulic driven haulage only winch. The radial piston hydraulic motor drives directly a shaft through the drum of the first section of the winch. The shaft of the second drum section is coupled to this shaft and the 2 sections are bolted together. Each drum can be driven independently off the common drive-shaft via a sliding ‘dog’ coupling. Each drum has its own foot-pedal and lever operated, manual calliper brake which has a locking ratchet so it can be used as a parking brake. The motor is driven from an independent hydraulic supply (suitable HPU`s can be supplied by Rotrex) and the speed is variable using the lever of the control valve mounted on the motor end of the winch.
