Abstract

1478753 Propelling elevators INTERNATIONAL EUROLIFT ETAB 21 Aug 1975 [21 Aug 1974] 34762/75 Heading B8L An elevator car or platform is driven up and down a fixed screw 4 by a nut 5 threadedly engaging the screw and driven by the hollow rotor 8 of a motor 3 mounted on a plate part 10 of the car, the screw 4 extending co-axially through the rotor 8 and through plate part 10, The motor 3 which is secured to a plate 9 adjustably mounted below the plate part 10, includes a co-axial tube 12 integral with the rotor 8, the tube 12 transmitting drive to the nut 5 through a friction coupling 18 and a ring 17 secured to the nut. A normally unloaded safety nut 19 is spaced below the nut 5 and is driven along the screw 4 by rods 20 on the nut 5 axially slidably engaging the nut 19. The elevator car is braked by an electromagnetically operated strap 23 acting on a brake wheel 22 secured to the top of the tube 12. At the lowest position of the elevator car, it is arrested, but the rotor 8, the tube 12 and the nut 5 continue to rotate downwardly to bring the underside of the brake wheel 22 into engagement with a friction disc 25 secured to the plate 9 whereupon rotation of the rotor 8 is stopped.
