  • Self aligning truck trailer
    Patent number: 4405144
    Abstract: Trailer and trailer connector for tractor/trailer for carrying elongated, self-supporting load. Tractor has conventional swivellable front bunk for supporting front of load, and trailer has a wheeled rear bogey and a non-swivelling rear bunk for rear of load. The trailer connector has a flexible link and a forward connection which connects forward end of link to front bunk and a rear connection which connects rear end of the link to the trailer. Length of the link does not change while towing the trailer and thus maintains tractor/trailer wheel alignment prior to loading. Trailer connector is considerably lighter than conventional telescopic trailer reaches, thus increasing maximum payload of tractor/trailer, and is less costly and easier to maintain than trailer reach, and also provides a more stable load platform.
