Depending on the operating requirement and the physical size and shape of the loads to be handled, Wheelift In-plant self-propelled modular transporters may have from four to ten axles or more in a single frame.  OR, several transporters can be used under a single load.  Properly positioned and in communication with each other multiple transporters can operate in fully synchronous travel. Every axle will be parallel for straight linear movement or all point to a single floating radius point in response to the operator’s movement of the joy stick on his wireless controller.
