or both. With the pole derrick many of these moves can readily 

 be accomplished without in any way disturbing the wire or cable 

 loads. The derrick pulls the pole out of the ground and with the aid 

 of the truck, the pole with its load intact is moved to the new location 

 where it is lowered into the hole prepared without even untying a 

 wire or loosening a cable clamp. It will also be readily appreciated 

 that the rehandling of cable and particularly the untying of open 

 wires is not only an expensive operation in point of first cost, but 

 that each such operation is distinctly detrimental to the plant, shorten- 

 ing its life and greatly increasing maintenance expenses. It will be

seen, therefore, that the use of the derrick where practicable in con- 

 nection with the moving of existing lines will largely eliminate the 

 undesirable and costly procedure which is involved in the manual 

 handling of the poles. 



As an example of one of the many uses to which the pole derrick 

 can very satisfactorily be put, Figs. 3 and 4 illustrate the initial and 

 final steps in moving back a pole in a 6-arm lead of wires and lifting
