The Hydraulic Winches work on simple planetary principle. Hydraulic winches come with inbuilt Hydraulic Brake. Winches can be supplied in electrically driven version. Winch drives consist of a Planetary gear unit, with its outer casing rotating and fitted to the drum. Thus the Designer has the freedom to design the Rope and the Frame to best suit his application while having the standard transmission ratio. The unit is equipped with Hydraulic fail safe wet type multi disc or Electromagnetic brake. The brake is released hydraulically or electrically.
