A pallet truck including a fork assembly. The truck includes a truck body and a control handle extending from the truck body. The fork assembly includes at least one elongated fork fixed to the truck body for vertical movement. The fork includes a top wall extending between fork ends and a pair of side walls extending from opposing edges of the top wall to form a downwardly opening cavity extending at least partially between the fork ends. A pair of opposing intermediate blocks are rigidly fixed to the fork and define a space therebetween. Each block is adjacent one of the fork sides and has a pivot shaft bore formed therein. The pivot shaft bores are coaxial. A shaft extends through the space between the intermediate blocks, into the pivot shaft bores, and short of the fork sides. The shaft has a shaft axis. A pivot arm has one end fixed to the shaft, and is pivotable about the shaft axis. A support wheel is rotatably fixed to an opposing end of the pivot arm.
