ABSTRACT:
The weight transfer device is for a tractor trailer including a tractor for pulling a trailer. The device comprises a mount having opposite ends provided with attaching elements for attaching transversely the mount between a pair of rearward parallel frame side rails of the tractor behind its fifth wheel. The mount receives the base of a bag unit having an upper surface over the base at an adjustable distance therefrom, and an inflatable air bag between the base and the upper surface for adjusting the distance. A bearing structure is mounted on top of the upper surface for upwardly pushing against the trailer without significantly hindering its pivotal movement around the fifth wheel. The device further comprises a compact guiding mechanism for vertically guiding the upper surface of the bag unit while preventing the bag from drooping when the bearing structure is pushing against the trailer. The guiding mechanism consists of an elongated member having an end connected to the upper surface and an opposite end projecting downwards therefrom inside the bag, and an upright sleeve connected to the mount beneath the bag for slidably receiving the opposite end of the elongated member.
