This invention concerns dual rail transportation system (1) used with roller pallets on which the wheels (2) of at least one pair of wheels are swiveling. On the margins of the running surface (5) of one rail (4) have been provided relatively low steering flanges (6) with a spacing (a) nearly the same as the breath (b) of the wheel traveling thereon. The other rail has a flat running surface sufficiently wider than the surface (5) of the one rail (4) to permit swiveling of the wheel traveling thereon. The roller pallet will hereby be steered with high accuracy on the rails.

Dual rails for roller pallets

A pick-up means for roller pallets in such applications where the roller pallets (1) run on rails (2) on tracks (3). At the discharge end of the tracks there is a stop (4) preventing the discharge of roller pallets until a pick-up means (6) provided with a travelling surface (5) comes to get the roller pallets meant to be dispatched. The pick-up means of the invention is characterized in that it comprises a slide (8) movable in its longitudinal direction and provided with a transporter (7), said slide being at a pick-up operation movable in under the first roller pallet (1) on the rails (2), while at the same time it will disengage the stop (4) so that the roller pallet moves onto the travelling surface (5) of the pick-up means, being pulled by the slide (8). The pick-up operation is now accomplished with considerably greater safety and speed than with any apparatus of prior art.
