We recently supplied two planetary winch gearboxes to be used in hydraulic Constant Tension (CT) winches for offshore use. These are winches that are used to achieve a constant line-pull. With the existing range of the well-known WD winch drives, we already had 3- and 4-stage gearboxes suitable to drive compact winches. In this case the constant tension winches required a low ratio for which Dinamic Oil produced 2-stage WD winch drives.
Due to the many years of cooperation between Dinamic Oil and Aandrijf Technisch Buro, we were able to engineer and supply a complete solution for this application. Let's hope this is the starting signal for a new range of 2-stage WD winch gearboxes.
