Abstract
A powered pallet truck with a selectable effective reduced turning radius, and an intermediate roller assembly for mounting on the powered pallet truck, are provided. The intermediate roller assembly can include a base, a linear actuator pivotably connected at a base end to the base, a linkage pivotably connected to the base, and at least one roller having an axis pivotably connected to an actuating end of the linear actuator and to the linkage, the at least one roller thus being movable between a retracted and an engagement position. The assembly can be mounted to the underside of a pallet truck fork having a load wheel. A turning radius effectively defined by a drive wheel of the pallet truck and the intermediate roller, or a turning radius effectively defined by the drive wheel and the load wheel, can be selected.
