Common Advantages to Both Single and Double Drum

  • HI-STRENGTH ALUMINUM GEAR HOUSING
  • LIGHTWEIGHT REVERSIBLE MOTOR
  • DOUBLE REDUCTION WORM GEARING
  • BALL AND ROLLER BEARINGS
  • SEALED GEARS
  • EASY MOUNTING

Patented trigger-duodynamic™ electrical braking in conjunction with reversible universal motor plus double reduction self-locking worm gearing gives the operator safer control.

Single Drum Winch Features

  • SIMPLE CABLE ATTACHMENT
  • LARGE 3 INCH DIAMETER FOR LONGER CABLE LIFE

IMPORTANT 1) First cable layer should have at least the first five wraps not in use. 2) Each additional cable layer reduces capacity. A block and tackle arrangement doubles capacity and cable on drum but reduces line speed by one-half.

Double Drum Winch Features

  • SPECIALLY GROOVED STEEL DRUMS
  • HEAVY DUTY DRUM SUPPORT BEARINGS

Double Drum Winches

Series Drum Cable Layer Lift Capacity (lbs.) Line Speed (ft./min.)
Full Load No Load
1200 Continuous 1200 17 28
700 Continuous 700 34 56

INCLINE DATA: All winches can pull much greater loads than they lift. (Ex: Series 1200, using first cable layer, can pull 15,200 lbs. running on casters up a 5% grade. This considers a 3% rolling friction.) Try our load calculator for more information

Line Speed will vary with voltage input. Figures are based on line voltage at motors (115v or 230v).

Cable on Drum

Cable Diameter (inches) Drum Capacity (feet) Breaking Strength (lbs.)
1/8 512 2,000
5/32 325 2,800
3/16 215 4,200
7/32 165 5,600
1/4 135 7,000

Galvanized aircraft cable, 7 x 19, is recommended for strength and flexibility.

IMPORTANT: Cordem specifies a minimum cable safety factor of 5:1 and a Safety Latch on all hooks.
