W. W. Patterson (USA) has developed a new, patent-pending release mechanism for its 40-ton manual barge connector winches. The new mechanism increases operator safety and efficiency when working under maximum loads. It consists of two heavy-duty drum gears with dual locking dogs and counterweights. The gears are offset by half a pitch. By setting one counterweight forward and the other counterweight back, operators can release loads one notch at a time.
The above feature provides greater precision, control, and safety over single gear designs. It also allows operators to make-up or break-up a tow in approximately half the time needed with conventional rigging that uses ratchets, chains, and wires. Patterson’s mechanism is available on its WWP40DG series barge connector winches. These units feature a low, 25” profile that’s easy to work around, a patented connector design to reduce the time and effort of clean-outs, a heavy-duty gear shroud to protect operators, and a built-in rope guard to prevent wire rope from fouling.
