The Clyde Frame 6 is a heavy-duty, industrial-grade winch or hoist, frequently used in demanding applications such as marine construction, rigging, mooring, and derrick operations. Designed by Clyde (a well-known name in industrial lifting and pulling equipment), these winches are heavily relied upon for lifting large loads and tensioning wire rope.

General Specifications

• Configuration: Commonly built as a double-drum or triple-drum "waterfall" winch. The waterfall design staggers the drums, saving horizontal space and allowing the wire ropes to spool evenly without crossing each other.

• Drum Dimensions:

  • Flange Diameter: 34 inches

  • Barrel Diameter: 15 inches

  • Barrel Length: 27 inches

• Line Pull (Stall/Bare Drum Pull): Typically rated around 35, 000 to 36, 000 lbs on the first layer (bare drum pull).

• Cable (Wire Rope) Capacity:

  • 3/4 inch: 2, 920 feet

  • 7/8 inch: 2, 150 feet

  • 1 inch: 1, 600 feet

• Weight: Approximately 9, 275 lbs (for a standard double-drum setup).

• Controls: Depending on the exact build, they can feature manual controls or heavy-duty air-controlled (pneumatic) setups.

Power Plant

The Clyde Frame 6 is usually driven by a diesel engine paired with a torque converter to provide smooth, continuous pulling power without jerking the load. Typical engines used to power these winches include the Detroit Diesel (such as the 3-53, 4-71, or 6-71 models) or Caterpillar (like the C4.4) engines. They are commonly mated to Allison or Twin Disc single-stage torque converters.
