Abstract: A portable trailer supports a long horizontal tube on which is mounted a rotatable and reciprocable drum and a fixed storage reel. The center tube, reel, and drum contain alignable longitudinally extending radial slots therethrough. Attached to the drum and extending over the reel is a bail and a series of snatch blocks. A slack cable is inserted transversely through the aligned slots in the drum, center tube, and reel such that it lays in the interior of the center tube. The cable is looped inside the reel and then transversely inserted into the bail and snatch blocks. Rotating and reciprocating the drum neatly winds the cable onto the storage reel from a supply reel, although there is no access to the cable ends.
