An expanding independent load suspension system that incorporates a square walking beam, unique bushings, and multiple expanding sliding units to spread the load bearing tires evenly over the surface instead of grouping them close together. With the weight of the vehicle having the ability to pivot over three separate axes, it maintains an equal pressure on all the tires no matter what the surface conditions. Additional benefits are derived by the separation of the tires with the new design of the square walking beam causing less damage to the roadways. The vehicle has been designed to operate on the highways in the conventional ten-foot width, and then expand to a maximum of twenty feet to move large loads with the permits required.
