Abstract
Transportation apparatus including an endless belt having platforms, pallets or steps attached thereto. The endless belt is driven in a guided loop through load bearing and return runs interconnected by turn-arounds at the ends of the loop. Guide rollers and guide tracks cooperate to guide the endless belt, with the guide tracks associated with the load bearing and return runs being connected in the turn-arounds via dynamic transition apparatus including cooperative guide track structure which enables normal manufacturing and assembly tolerances to be observed while automatically compensating for wear. The apparatus constantly seeks the best adjustment mode, providing smooth operation with minimal noise and vibration.
