Novawinch HW-250/NH features:

  • Integrated hydraulic motor and automatic brake assembly partly located inside winch drum – provides compact size to make mounting easier.
  • Wire rope capacity of over 60m to meet various demands.
  • Drum diameter to rope diameter ratio is 12:1 to ensure rope breakages are avoided.
  • High torque hydraulic motor, 3 stage planetary gearbox and self-adjusting gear design provides strong pulling capacity and efficiency.
  • Oil bath gearbox for added efficiency
  • Water tight and internal anti-heat rubber seals.
  • Overflow valve can be added as optional extra.
  • Meets EN 14492-1:2006 requirements:
    (1)The first layer of wire rope safety factor (breaking strength/rated pulling) must at least 2 times of winch rated line pull.
    (2)Space between drum and tie bar should be 1.5 times of the wire rope diameter.
    (3)(Drum diameter + rope diameter)/ rope diameter ≥ 10;
    (4)Two wire rope mounting holes on the drum for safety operation;
    (5)Winch mechanical structure reach 1.25 times of winch rated line pull.
