Roll-off trailer
Abstract
Abstract A ROLL-OFF TRAILER COMPRISING A SUPPORT FRAME AND A MAINU FRAME PIVOTALLY MOUNTED THEREON AT THE REAR THEREOF. THE REAR WHEELS OF THE TRAILER ARE SLIDABLE RELATIVE TO THE SUPPORT FRAME WHEREBY THEY MAY BE MOVED FROM THE REAR OF THE SUPPORT FRAME TO AN INTERMEDIATE POINT ON THE SUPPORT FRAME. THE SUPPORT FRAME COMPRISES TWO PIVOTALLY LINKED SECTIONS WHICH ARE LINKED AT THE INTERMEDIATE POINT TO WHICH THE REAR WHEELS MAY BE MOVED. BY PIVOTING THE SUPPORT FRAME AT THE INTERMEDIATE POINT, A SMALLER ROLL-OFF ANGLE IS ATTAINED THAT THAT WHICH WOULD BE OBTAINED WHEN USING THE PRIOR ART UNSPLIT SUPPORT FRAMES ON ROLL-OFF TRAILERS. HAVING THE SMALLER ROLL-OFF ANGLE FACILITATES THE LOADING AN UNLOADING OF CONTAINER BODIES AND CARGO ON THE MAIN FRAME.
