winches, its size and weight were such that it could not well be used 

 on trucks of less than 5-tons capacity. It will be noted that the 

 winch extends well up to the cab window and would practically fill 

 the front end of the body. Its net weight exclusive of the truck 

 power take-off was 2,300 pounds.

The desirability and in fact the indispensable need of using winches 

 on the smaller trucks has led to the development of a very compact 

 light weight unit which will handle about 900 feet of 7/16" steel 

 rope and withstand a pull of 10,000 pounds on a single line. Ex- 

 perience indicates, that this winch is capable of meeting the maximum 

 requirements generally encountered in construction work. 



The compactness of this winch is illustrated by Fig. 18 which shows 

 it below the cab window with only the upper half of the drum pro- 

 jecting above the floor line in order to give the rope proper clearance 

 in winding and unwinding. This winch weighs slightly less than 

 500 pounds. 



In closing this discussion of motor vehicle application to telephone 

 work it might be of interest to examine the curve in Fig. 19, which 

 shows the rate of growth of the motor vehicle fleet in the Bell 

 System. 



This curve prepared from such information as is now available 

 presents a reasonably accurate picture of the motor vehicle develop- 

 ment which began in the Bell System as early as 1904.
