4HBP SERIES HEAVY-DUTY ELECTRIC POWER WINCHES
HIGH-TORQUE PLANETARY GEARING
Moves the Heaviest Loads The 4HBP Series of power winches (35,000 to 100,000 pounds) is designed for the heaviest loads that require fast line speeds over long travel distances. Planetary gearing
provides high torque in a compact envelope while providing high efficienciesâup to 88 percent. A modular design allows easy customization to exact customer specifications. Perfect for mining, rail
car positioning, and construction.
Modular Design
- Flexible winch design allows customization by Thern to meet specific customer requirements
Integral Drum and Shaft Design
- Large-diameter, welded-steel drum, featuring outside flange anchors, promotes uniform winding and extends life of wire rope
- Anchors allow cable to be over or under wound and allow multiple drum exit angles
- Flange-style, self-aligning roller bearings with cast-iron housing maintain smooth drum rotation
- Continuous, solid-steel drum shaft and steel frame provide optimal strength and security
- Complete wire rope assemblies available upon request
Durable Gears and Gearbox Design
- High-torque, helical-bevel/planetary gears allow high line-load ratings with large drum diameters
- Fully enclosed, direct-drive gearing delivers dependable operation with minimal maintenance
- Large-capacity bearings enhance smooth operation and durability
- Sealed, cast-iron gearbox with integral oil bath for direct-drive gearing dissipates heat and provides continuous lubrication for enhanced service life
- Primary speed reducers meet AGMA and/or DIN standards
Energy-Efficient Premium Motor
- Energy-efficient 230/460 volt, reversible, three-phase, 60-cycle industrial-grade motor endures continuous use. Also available in worldwide power supplies
- A totally enclosed, fan-cooled (TEFC) design, featuring IP66 and F-class insulation, resists debris and contamination for long service life
- Standard motors comply with industry standards: UL, CSA, IEC, and NEMA MG1
