A roller conveyor or roller track includes a delivery end having a stop against which materials which are carried on a pallet are delivered. The delivery area includes control means in the form of a lever which is located adjacent the end stop in a position such that it is depressed by the material or its pallet when it arrives at the delivery point. The lever is connected to control means which is engageable with the next quantity of material or its pallet which is delivered toward the delivery point. The control means is effective to hold the next pallet at a spaced location from the pallet which has already arrived at the delivery point so that it will not interfere with this pallet when the latter is removed such as by a fork truck which is engageable therewith. As soon as the pallet is removed from the delivery point, the next pallet may move forwardly to the end position of the delivery area adjacent the stop in a position at which it may be engaged for removal without interference from the pallet which is next to the delivery area.
