ROBUST CONSTRUCTION for Dependable Heavy-Duty Service The Spur Gear Series of hand winches (up to 10,000 pounds) is designed to lift, lower, and position heavy loads, dependably.
It is also a perfect solution for high-capacity stabilization and tensioning needs. The rugged design features heavy steel construction, machine-cut steel gears, bronze bushings, and radial ball
bearings. You can count on long, rugged service life for many applications, like construction and aerospace.
Features:
- Spring-Loaded Ratchets and Locking Mechanism - Ratchets automatically engage to hold loads securely when winch is not being operated ⢠Frame-based, gear-locking
mechanism enhances load control
- Adjustable Handle - Adjustable handle provides ability to increase mechanical advantage or speed accordingly as load weight varies
- Steel Gear Guards - Steel-encased gear guard enhances safety
- Solid Steel Machine-Cut Gears - Precision-cut, zinc gears resist corrosion, increase efficiency, and provide precise operation for outdoor use
- Available Non Brake Units - Non-brake unit allows additional flexibility in horizontal pulling applications only - Two gear ratios increase efficiency, depending on
load
- Automatic Weston-Style Brake - Spring-engaged, ratchet- pawl design offers additional reliability and positive load control for lifting and lowering - Enclosed
(pawl and ratchet) envelope keeps brake clean, dry, and protected for reliable service and haptic feedback - Durable friction discs reduce wear and increase service life
- Welded Steel Drum - Robust drum design and large spool diameter minimizes drum wear and extends wire rope life

WORM GEAR SERIES
MEASURED, STEADY PRECISION with Less Force The Worm Gear Series of hand winches (up to 4,600 lbs) is designed to lift and lower heavy loads quietly, with less effort. The worm-gear
design allows for more precise positioning and extra load-holding power for secure control. Machine-cut bronze gearing and a cast aluminum gearbox enhance durability and resist the elements.
Multiple configurations make it ideal for maritime, rail yards, construction, and manufacturing.
Features:
- Adjustable Handle - Adjustable handle provides ability to increase mechanical advantage or speed accordingly as load weight varies
- Machine-Cut Bronze Gears - Bronze worm gears reduce noise, enhance precision, and extend service life while facilitating drill-drivable operation - 4WM2 and 2W40-BM Models
- Flexible Operation Design - Operate winch using adjustable handle or portable drill-drive on 4WM2 and 2W40-BM models for longer lift applications that lack a permanent power supply - Drill
drive operation* allows faster lifting/lowering speed (400 RPM Drive Maximum)
- Enclosed Oil Bath - An oil bath provides continuous lubrication of gearbox components to minimize wear, extend life, and reduce maintenance
- Cast-Aluminum Gear Box - Lightweight, corrosion-resistant design enhances portability and increases service life
- Automatic Brake - Adjustable brake provides positive load control for lifting/lowering • Oil bath provides continuous lubrication to reduce heat, minimize wear, and extend service life
- Load-Locking Mechanism - Frame-based, gear-locking mechanism enhances load control
- Large-Diameter Drum - Large diameter drum extends wire rope life and increases travel distance
IMPORTANT: It is the owners or operators responsibility to determine the suitability of the equipment to its intended use. Study all applicable codes, manuals and
regulations. Be sure to read the Owners Manual supplied with the equipment before operating it.
