Dolly for transporting prefab homes and the like

Abstract

A wheeled dolly for transporting prefab homes or the like and having at least two outboard wheel means spaced apart a distance for normal road travel, and further having at least two inboard wheel means on opposite lateral sides of a longitudinal axis of the dolly whereby when a narrow roadway is encountered the operator can position the inboard wheel means thereon such that either or both of the outboard wheel means may actually be suspended off the sides of the roadway until the roadway regains a normal width, and wherein a steering mechanism is provided to synchronously pivot all said wheel means thru a steering angle whereby the dolly and load can be steered straight ahead or in sideways angular directions to avoid obstacles and to allow maneuvering of a long load around corners which are too sharp for conventional transport means.

I claim:  
     
         1 . A wheeled dolly structure comprising base means having a longitudinal axis and being of heavy, strong steel construction capable of carrying 5 to 30 or more tons of load and transporting the same over difficult roadways wherein girder means are provided on the dolly and are adapted to be connected to supporting beam means of a load, a plurality of axle means mounted on said base means on lateral axes normal to said longitudinal axis and lying on opposite lateral sides thereof, outboard wheel means mounted on outboard axle means and spaced from each other a distance of at least about eight feet, inboard wheel means mounted on inboard axle means each of which is laterally spaced from said longitudinal axis a distance of at least about one foot, whereby when a narrow roadway is encountered the operator can position the inboard wheel means thereon such that either or both of the outboard wheel means may actually be suspended off the sides of the roadway until the roadway regains a normal width, and wherein a steering mechanism is mounted on said base means for synchronously pivoting all said wheel means thru a steering angle whereby the dolly and load can be steered straight ahead or in sideways angular directions to avoid obstacles and to allow maneuvering of a long load around corners which are too sharp for conventional transport means.  
     
     
         2 . The dolly structure of  claim 1  wherein said outboard wheel means are spaced from each other on said lateral axis a distance of at least about nine feet, and wherein said inboard wheel means are spaced from each other on said lateral axis on opposite sides of said longitudinal axis a distance of at least about two and one half feet.  
     
     
         3 . The dolly structure of  claim 1  wherein each wheel means comprises single or dual wheels mounted on the same axle.  
     
     
         4 . The combination of the dolly structure of  claim 1  mounted on and affixed to supporting beam means of a manufactured home.
