Examples provides one or more rolling pallet trays capable of interlocking together to form a modular rolling platform. A rolling pallet tray includes a rectangular base member with a top surface, a bottom surface, and a set of four sides. The top surface may have a lip extending upward along at least a portion of the circumference of the top surface. A set of rollers are pivotally mounted to the bottom surface. A floor-lock brake may be activated to stop movement of at least one roller to lock the rolling pallet tray in place. A set of linking mechanisms is attached to one or more of the sides for linking the individual rolling pallet tray to one or more other rolling pallet trays in a variety of different configurations. The linked rolling pallet trays in the modular rolling pallet tray pivot together as a single unit for greater stability.
