Cable Pulling Principles 

(cont’d)

Cable Pulling Forces 

(cont’d)

At the Capstan

The capstan acts as a 

force multiplier

. The operator 

exerts a small amount of tension, or tailing force, on the 

rope; the capstan multiplies this force to pull the cable. 

The resultant force depends upon the number of times 

the rope is wrapped around the capstan, as shown in 

the formula below.
Pulling Force  =  Tailing Force x e

0.0175µø

 

Where:

  e = the natural logarithm, or 2.7183

  µ

= the coefficient of friction between the    

rope and the capstan*

  ø = the number of degrees of wrap of rope    

around the capstan

*  The average value for the coefficient of friction when 

double-braided composite rope is pulled over a clean 

dry capstan is 0.125.

The following table is based on the formula above.  

The input, or tailing force, is constant at 44.5 N (10 lb). 

Increasing the number of wraps increases the pulling 

force.

  11.1 kN (2478 lb)

This table shows how the capstan acts as a force 

multiplier. Because the coefficient of friction depends 

upon the condition of the rope and capstan, this formula 

cannot determine an exact amount of pulling force.
