ABSTRACT:
A travelator system for conveying a passenger, comprising a main conveyor and a branch conveyor. The main conveyor includes a first plurality of shafts each having a first plurality of belt pulleys disposed side by side thereon. The main conveyor also includes a plurality of mutually parallel endless belt loops which define a moving conveying surface of the main conveyor, each belt loop being passed over a belt pulley on two different shafts. Adjacent belt loops on the same common shaft are passed over different belt pulleys such that a first belt loop is passed over a belt pulley on a previous shaft relative to the common shaft in a transport direction of the main conveyor, while a second belt loop is passed over a belt pulley on a following shaft relative to the common shaft in a transport direction of the main conveyor. The branch conveyor branches off of the main conveyor in a connecting section to allow passengers to enter from the branch conveyor onto the main conveyor and/or to exit from the main conveyor onto the branch conveyor. The branch conveyor is also implemented using shafts, belt pulleys, and belt loops similar to the main conveyor. In the connecting section, the branch conveyor and the main conveyor share at least one common shaft.
