Patent attributes
A transport vehicle for transporting payloads is provided. The transport vehicle includes primary and secondary chassis, and first and second sets of wheels for supporting the respective primary and secondary chassis. A guide arrangement is mounted on the primary chassis and the secondary chassis is slidably mounted on the guide arrangement. The primary and secondary chassis are parallel and spaced apart from each other. A payload lifting arrangement is positioned on a top surface of the secondary chassis to lift a payload. When a weight of the payload is below or equal to a threshold weight, the weight is distributed across the second set of wheels by way of the suspension arrangement. When the weight of the payload exceeds the threshold weight, the weight is distributed across the first and second sets of wheels by way of the guide arrangement and the suspension arrangement, respectively.
