4 Values based on 6x37 IWRC EIPS wire rope.
5 Values based on 7x19 galvanized aircraft cable.
Actual drum capacities 25-30% less, due to nonuniform winding. Wire rope tension will also affect drum capacity.
Wire rope should be selected based on the breaking strength to load rating ratio and application parameters.
Industry standards suggest a 5:1 breaking strength to load rating ratio for lifting and a 3:1 ratio for pulling.


  Features

Thern 4HPF series power winches feature helical/parallel, high efficiency gearing making them ideal for applications requiring long travel distances and faster line speeds. The enclosed, direct-drive gearing design delivers dependable operation and helps reduce maintenance, while a modular design means we can easily customize these winches to meet your exact specifications.

  • FLANGE MOUNTED MOTOR is a 230/460 volt 3 phase, 60 cycle, IP 55, TEFC severe duty, reversible, class F insulated, continuous duty brakemotor.
    Standard motors comply with relevant standards including NEMA, MG1, ANSI, CSA, IEC and ABS.
  • LOAD HOLDING MOTOR DISC BRAKE is spring set, electrically released for positive load control.
  • DIRECT DRIVE GEAR REDUCERS, comprised of helical/parallel gears, deliver high effi ciencies from 88% to 94% making winches well suited for applications requiring long travel distances and faster line speeds.
    The heat treated helical/parallel gear set provides improved durability and operates in an oil bath, enclosed in a high strength cast iron gearcase, SAE class 30. Double-lip oil seals keep oil in and contaminants out. Large capacity bearings ensure long life. Speed reducers meet AGMA standards.
  • FLANGE STYLE ROLLER BEARINGS are self-aligning with cast housings to maintain smooth drum rotation.
  • WELDED STEEL DRUM with outside fl ange anchors allow for uniform winding and help extend life of wire rope. Anchors allow cable to be over wound or under wound from either side of the drum.
  • EXTENDED SOLID STEEL DRUM SHAFT for uniform loading.

  • Options
  • DRUM MODIFICATIONS (A) include grooved drums, multiple compartment drums and modified drum widths and diameters.
  • MANUALLY OPERATED JAW CLUTCH (B) disengages for rapid payout of wire rope when not under load. Adjustable drag brake on the drum prevents over-spooling during payout. Clutch option is for horizontal pulling only.
  • WINCH MOUNTING OPTIONS include base, wall or under hung installation.
  • CABLE PRESSURE BARS (C) help maintain uniform winding of wire rope.
  • LIMIT SWITCHES (D) provide secondary shut-off for load travel in one or two directions.
  • MOTOR OPTIONS include air or hydraulic, voltage or phase changes, IP 65, class F or H insulated and multi-speed operation.
  • DUTY RATINGS include IEEE 45 marine duty, tropical duty, severe duty and explosion proof ratings.
  • BRAKE OPTIONS include over-speed, caliper style, band, and more.
  • CONTROLS (E) are available in a wide range of standard and custom confi gurations for single or variable speed.
  • CORROSION RESISTANT FINISHES for harsh or hazardous environments.
  • MANUAL OVERRIDES for winch operation in power loss situations.
  • WIRE ROPE ASSEMBLIES sold separately.
