New series of compact hydraulic winches. The winches, ranging from 3,600 to 30,000 kg, have as a standard feature the integrated negative lamellar brake and a manual declutch system (hydraulic or pneumatic are also available on request). A hydraulic motor-driven unit with variable displacement can also be installed on larger versions. The power generated by the hydraulic motor-driven unit is transferred to the drum by way of planetary gear units incorporated in the drum. A complete range of accessories, such as rope guides and pressure rollers, are available on request.
