ABSTRACT:
A standard wheeled dolly frame or pallet is connected to a carriage at one or opposite sides thereof. Each carriage has an elastomeric material for biasing a plurality of pivotally mounted driven wheels against a rotatable drive shaft extending along a transporting direction. The driven wheels are canted with respect to the drive shaft so that when the drive shaft is rotated by a belt driven by an electric motor and a mechanical transmission, a helical loci of engagement between the drive shaft and driven wheels provides sufficient traction through the engagement force of the bias member to propel the wheeled vehicle along the transporting path. Preferably, the drive shaft is composed of a number of discontinuous driving sections that are aligned or alignable for diverting transporting paths so as to each be driven by a separate set of a drive motor, mechanical transmission and drive belt. The drive shaft may include curved sections so that the transporting path may take on any desired shape. The drive shaft is mounted by a plurality of bearings within a channel.
