  • Trailer dolly
    Patent number: 6685211
    Abstract: A load-bearing trailer dolly which connects a tongue-type boat, utility or other trailer to a towing vehicle and bears weight from the trailer during towing. In a preferred embodiment, the trailer dolly is characterized by an axle mounted on a pair of wheels and an axle mount upward-standing from the axle. A dolly frame height-adjustable on the axle mount by operation of a crank-operated threaded rod includes a forwardly-extending drawbar for attachment to the drawbar receptacle on the towing vehicle and a rearwardly-extending hitch bar fitted with a hitch ball for engaging the trailer tongue on the trailer. A shock-absorbing spring is fitted between the axle mount and the dolly frame for cushioning the dolly frame on the axle mount as the trailer is towed behind the towing vehicle.
