Abstract
A hand truck carrier for securing a hand truck to a vehicle includes a carrier body and first and second members coupled to the body. The carrier body is attachable to the vehicle. The first and second members are selectively positionable in at least an open position and a closed position. In the open position, the members are spaced apart from each other to define therebetween a base plate receiving space in which a base plate of a hand truck can be received. In the closed position, the members are positioned closer to each other than in the open position, and to contact and apply a clamping force to top and bottom surfaces of the base plate, respectively, thereby securing the hand truck to the hand truck carrier.
