A roll coupling system (208) for linking a tow vehicle (4) and a drawn vehicle (6), the system (208) comprising: a roll coupling device (2) comprising, a roll coupling member (10) for coupling with a draw member (12), the roll coupling member (10) having upwardly and downwardly facing coupling surfaces (14, 238) adapted for slidable engagement therewith; a locking mechanism (20) for locking the roll coupling member (10) in connection with the draw member (12); and a support mechanism (16) for mounting the roll coupling member (10) on a tow member (18) of the tow vehicle (4); and the draw member (12) comprising, a wrap-around skid assembly (228) adapted to wrap over, around a side of, and under a portion of the roll coupling member (10), thereby slidably engaging the upwardly and downwardly facing coupling surfaces (14, 328) of the roll coupling member (10). |
