Reel trailers are in various designs and configurations.
They normally carry from 1 to 4 reels.
Care should be taken in the selection of a safe and functional reel trailer with capacities equal to the size and weight of the conductor reels.
A Manual Reel Trailer is most commonly used for underground construction.
This trailer allows the puller to remove the power conductor at its own speed with a manual over-spin brake to prevent overspending.
A Hydraulic Reel Trailer allows the operator to adjust the speed and tension of the conductor hydraulically as it flows from the reel stands.
However, care should be taken to ensure enough slack is available to prevent the reel trailer from pulling against the puller, which causes unnecessary tension on the conductor.
Regardless of the design, manual or hydraulic, the trailer should be equipped with a ball bearing on the reel shaft to prevent the additional pulling tension and friction required just to turn the reel.
