Description

  Embodiments of the present invention relate to a passenger conveyor and its mounting method.

  Passenger conveyors, such as escalators, are attached by trusses between the upper and lower floors. This bridging is performed by mounting a support angle projecting from the end of the truss on the anchor plate in the notched housing formed at the landing place on the upper floor side and the lower floor side. The length of the support angle projecting from the end of this truss is designed to satisfy the seismic resistance standard.

  However, recently, due to the change in seismic resistance standards, it is necessary to further increase the length of the support angle projecting from the end of the truss. However, in order to replace the supporting angle of the existing passenger conveyor, it is not easy to change the supporting angle because the entire passenger conveyor has to be lifted by heavy machinery.

  Therefore, it has been proposed to fix an extension member which protrudes outward beyond the existing support angle to the existing support angle.
