Towing winches are often used on tugboats assisting container ships and other cargo ships in ports and port terminals. The pulling and braking force, in combination with the transmission, determine the application of this type of winch. DMC’s towing winches, driven by gearboxes, are unique in use. This solution developed in-house ensures that the speed of the winch is automatically adjusted to the required pulling force. The variable speed allows the winch to always run at the highest possible speed. This eliminates the need to manually choose between two or three-speed models.
