Abstract:
An exemplary vertically moveable elevator system component includes a top portion, a bottom portion and a plurality of vertically oriented side portions between the top and bottom portions. At least one of the side portions includes a roller guide support sheet. A first roller guide roller is supported by the sheet such that the first roller is at least partially disposed on a first side of the sheet and an axis of the first roller is generally parallel with the sheet. Second and third rollers are supported by the sheet such that the second and third rollers are on a second, oppositely facing side of the sheet. An axis of each of the second and third rollers is generally perpendicular to the axis of the first roller. The axis of each of the second and third roller remains in a fixed position relative to the sheet.
