  • Elevator for large loads
    Patent number: 7549514
    Abstract: An elevator with a 4:1 cable guidance includes a drive unit and a first deflecting roller arranged at a carrier supported at one end on a first car guide rail and a first counterweight guide rail and at the other end on a second counterweight guide rail. The guide rails are connected with the shaft wall by means of yokes, whereby the vertical rail forces are conducted into the shaft pit. A drive bracket arranged at the carrier carries the drive unit and the drive pulley. A roller bracket arranged at the carrier carries the first deflecting roller. In addition, a first cable fixing point and a second cable fixing point for opposite ends of a cable are arranged at the carrier. The second deflecting roller is supported on a second car guide rail.

  • Assembly arrangement of a lift drive in a lift shaft
    Patent number: 7204348
    Abstract: An assembly arrangement for a lift construction supports the lift drive at the upper end of both a support column and lift cage and counterweight guide rails, allowing the lift drive load to be transferred to the floor of the lift by each of the supporting members. The support of the lift drive upon the rails may be accomplished through setting screws that allow the load applied to the rails to be adjusted.
