ABSTRACT:
A travelator, moving ramp or escalator comprises a conveyor having a driven end driven by a power machine and a non-driven end. At the driven end, a first drive element, in the form of an endless loop, is passed over a first driving pulley rotated by the power machine, and at the non-driven end the first drive element is passed over a first diverting pulley. A second drive element, in the form of an endless loop, is passed over a second driving pulley at the driven end rotated by the power machine, and over a second diverting pulley at the non-driven end. A first synchronizing device at the driven end provides mutual synchronization of the first and second driving pulleys. The conveyor additionally comprises a second synchronizing device arranged at the non-driven end for mutual synchronization of the first and second diverting pulleys.
