  • Patent number: 10669125
    Abstract: An elevator rope guide system comprises a plurality of rope guides for restricting the swaying of at least one main rope and a plurality of stop mechanisms each configured to stop a corresponding rope guide. The rope guides are located above an elevator car and/or counterweight and are vertically movable along a hoistway. The stop mechanisms are positioned at different intermediate heights along the hoistway. The elevator rope guides are collected by the elevator car or counterweight as the elevator car or counterweight moves up and are stopped by a corresponding stop mechanism as the elevator car or counterweight moves down.

  • Patent number: 5831226
    Abstract: Multiple elevators are installed as a group in a building and are equipped with destination floor boarding location buttons (7), (8), (9) and (10) that are provided on the lobby floor. Multiple car controllers (1), (2), (3), (4) and (5) are input car data for each elevator so that the controllers control the operations of each elevator. A higher level controller (6) is provided with input data from the multiple car controllers and call data and that efficiently operates multiple cars while accommodating changes in traffic demand. When it is determined that higher level controller (6) is in service, all the floors are divided up into sectors and cars are quickly dispatched to the aforementioned sectors in response to the aforementioned destination floor boarding calls, and the sequencing of service in each sector will be in the order in which each destination floor boarding call has occurred.
