TRAVELOR, MOVING RAMP OR ESCALATOR

摘要

A travelator, moving ramp or escalator, comprising a power means (1) and a conveyor (2) having a driven end (3) driven by the power means (1) and a non-driven end (4). The conveyor comprises a first drive element (5) and a second drive element (6), which are at a distance from each other and parallel to each other, each being formed as an endless loop. A number of transport platforms (7), such as pallets or stairs, are arranged one after the other and secured to the first (5) and the second (6) drive elements. The first drive element (5) is passed at the driven end (3) over a first driving pulley (8), which is rotated by the power means (1), and at the non-driven end (4) over a first diverting pulley (9). The second drive element (6) is passed at the driven end (3) over a second driving pulley (10), which is rotated by the power means (1) , and over a second diverting pulley (12) at the non-driven end (4) . Placed at the driven end (3) are first synchronizing means (12) for mutual synchronization of the first driving pulley (8) and the second driving pulley (10). The conveyor (2) additionally comprises second synchronizing means (13), which have been arranged at the non-driven end (4) for mutual synchronization of the first diverting pulley (9) and the second diverting pulley (11).
