General Purpose

Wire Rope

The length of rope that can be wound on a drum or reel may be calculated as follows. L = the length of rope in feet. All other dimensions are in inches.

 

L = (A + D) x A x B x K 

K = Constant obtained by dividing .2618 by the square of the actual rope diameter. 

A = (H-D)/2 Desired clearance, in inches. 

B = Traverse in inches. 

D = Barrel Diameter in inches. 

H = Flange Diameter in inches. 

L = Rope length in feet.
