- 23 - LOAD SHIFTER ASSEMBLY FOR TRAILERS ABSTRACT OF THE DISCLOSURE A tandem axle load shifter is detachably engage- able on the rear end of a trailer and includes a suspension frame assembly with tandem axles and wheels, connected to a pick-up frame assembly by means of a turntable for self- steering purposes. The pick-up frame assembly is detach- ably secured to the rear end of the trailer and has a guide wheel journalled on the underside thereof. A curved and ramped rail is secured to the suspension frame forwardly of the wheels and engages the guide wheels so that when the suspension frame turns, the rail rides up the wheel and the loading of the rail on the guide wheel assists the suspen- sion frame assembly to return to the central position when the turn is completed. The mounting of the turntable is such that the vertical axis thereof is forwardly of the horizontal center line between the two axles thus giving a castoring effect to the suspension portion of the assembly which assists in maintaining the straight ahead trailing relationship of the assembly relative to the trailer under normal conditions.
