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.

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

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.
