A method for changing the direction of motion of a pallet moving on wheels at an end of a travelator. The method comprises moving the pallet in a traveling direction at a first level, positioning a supporting element in alignment to receive a wheel of the pallet using a positioning device, positively guiding a trailing end of the pallet from the first level to a second level different than the first level by supporting the wheel of the pallet with the supporting element, and moving the pallet in a return direction at the second level. The pallet maintains a substantially constant orientation during the change of direction of motion.
