Cable Reel Trailers 



To meet the need for a device suitable for trailing a single reel of 

 cable and also for use as a reel "set-up" preparatory to a "pull" of 

 either underground or aerial cable, a type of cable reel trailer has 

 been developed as illustrated in Figs. 9 and 10. 



A number of trailers of this type have been in service for some 

 length of time and their use has brought out many advantages, some 

 of the more important of which are: 



A reel of cable can be loaded on and unloaded from the trailer 

 in less time and with less effort than when a reel is carried in the 

 body of the truck. In this connection, it might be pointed out 

 that an important safety feature is involved in that the hazards 

 to the men in loading and unloading heavy reels of cable by the 

 old method are practically eliminated. Of course, even where 

 reels of cable are carried in the truck the use of the winch and 

 spindle as previously discussed in the January issue eliminates 

 the hazard that was present in the old method of loading and 

 unloading, involving, the use of skids.
