A load handling system for a vehicle includes a set of forks that concurrently supports two or more pallets including a first pallet and a second pallet linearly positioned along a length of the forks, and a lifting system to raise and lower the forks. A traction system moves the vehicle in a direction of travel associated with withdrawing the forks from the pallets. Additionally, an actuation device generates an activation signal in response to being actuated by an operator, and a vehicle controller places the vehicle in an automated mode of operation in response to receiving the activation signal. In the automated mode of operation, a front end of the forks moves from the second pallet to the first pallet, and the first pallet is raised while the second pallet remains on a transport surface. The first pallet is then spaced apart from the second pallet by a predetermined distance and then lowered to the transport surface.

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.
