Rapp Marine’s New Electric Tow Winch Design

Rapp Marine has more than a decade of experience of designing and delivering towing winches for workboat market, towing winches mainly powered using hydraulic systems. While some tugboat operators have maintained their preference for hydraulic driven winches, Rapp Marine recognized a growing demand in the workboat industry for electric driven winches and equipment for their new construction vessels, with electric winches offering advantages such as ef? ciency in energy

Rapp Marine has been delivering electric winches to commercial vessels in other industries such as research, oil & gas, and ? sheries for years. Rapp Marine has designed a fully electric driven tow winch to meet market demand. Driven by a single 75, 100, or 125 HP motor, the winch can pull more than 50 tons and uses pneumatic cylin- ders in place of hydraulics, keeping the ? uid off of the deck. The brakes offer a force of 250-300 tons on the barrel layer. The winch will feature an emer- gency payout system, and constant tension capability is available as an option. Both single drum and double
