With load capacities up to 25,000 lbs., Thern 4HPF series power winches are engineered with helical/parallel, high efficiency gearing making them perfect for applications requiring longer travel distance and fast line speeds. The enclosed, direct-drive gearing design of the HPF Series delivers reliable operation and helps reduce maintenance costs, while a modular design means Thern can easily customize these winches to fit your application.


FLANGE STYLE ROLLER BEARINGS are self-aligning with cast housings to maintain smooth drum rotation.
WELDED STEEL DRUM with outside flange 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.
FLANGE MOUNTED MOTOR is a 230/460 volt 3 phase motor, 60 cycle, IP 55, TEFC severe duty, reversible, class F insulated, continuous duty brake motor. Standard motors comply with relevant standards including NEMA, MG1, ANSI, CSA, IEC and ABS.
DIRECT DRIVE GEAR REDUCERS, comprised of helical/parallel gears, deliver high efficiencies 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.
LOAD HOLDING MOTOR DISC BRAKE is spring set, electrically released for positive load control.
WIRE ROPE ASSEMBLIES sold separately per customer request.
ANSI B30.7 COMPLIANCE is available. Please contact the mdi.
Two-year Limited Warranty

warning important

  • Drum modifications include grooved drums, multiple compartment drums and modified drum widths and diameters.
  • Manually operated jaw clutch 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 help maintain uniform winding of wire rope.
  • Limit switches 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 are available in a wide range of standard and custom configurations 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
  • Wire Rope Primer
