<p>The escalator has a truss (4) and a shaft (5). A shaft-bearing has two sockets, each arranged on an opposed end of the shaft for holding the shaft in the truss. The shaft-bearing comprises a hub, where hub is tightly fastened to the truss and supports the socket. The shaft is borne by the socket, where the shaft is mounted upon the hub by the socket. The socket is adapted and constructed to be movable along the shaft. An independent claim is also included for a method of supporting a shaft of an escalator by a shaft-bearing in a truss.</p> |
