  • Fig. 1 shows an elevator 100 with an elevator car 10 movably along guide rails 104 and mounted within a shaft 102 of a building.
  • the building comprises several landing floors, inter alia landing floors 70, 72.
  • an elevator car drive 106 having a traction pulley 107 is mounted in a machine room on the top of the shaft 102 .
  • the elevator drive system in Fig. 1 shows a guide pulley 108 and a traction belt 109.
  • the elevator car 10 comprises a casing 12 supported by a frame (not shown), wherein the casing 12 includes a ceiling 15, a bottom 16, walls 17 and a car door 18. Furthermore, the car 10 has a support 20 in the form of a platform for the payload to be transported by the elevator car 10. This platform divides the space enclosed by the casing 12 into an upper area 13 and a lower area 14.
  • a support levelling system 30 is provided in order to level or move the support 20 in a specific levelling range R.
  • the support 20 can be levelled independently from the elevator car 10.
  • the support levelling system 30 comprises a support drive 40, for example a telescopic piston 42.
  • the elevator car 10 comprises a support drive control 50 and a support position system 60.
  • the support position system 60 comprises a sensor 62 integrated in the support platform and a receiver 64 mounted on each landing floor 70, 72. Sensor 62 and receiver 64 communicate with each other and with the support drive control 50 in order to determine the position of the support 20 relative to the landing floor level 70.
  • the support drive control 50 initiates a signal to the support drive 40 in order to move the platform 20 in a direction to bring the surface of the support 20 within the levelling range, especially to the exact landing height of the landing floor 70.
  • the elevator system of Fig. 1 further comprises a car position system 110 having a sensor 112 mounted to the casing 12 of the car 10 and receivers 114 mounted along the shaft 102, for example at the landing floors 70, 72.
  • a car position system 110 having a sensor 112 mounted to the casing 12 of the car 10 and receivers 114 mounted along the shaft 102, for example at the landing floors 70, 72.
  • the car position system 110 comprises a car control unit 120, a main electric drive and/or frequency converter 130 and a main elevator controller 140. Based on this car position system 110, the "raw” car position can be derived from the main motor relative distance. The raw car positioning algorithm is distributed and achieved by a "triangulation" between car control unit 120, main electric drive or frequency converter 130 and main elevator controller 140. In other words, the car position system 110 serves as a "raw” levelling system, whereas the system 30 serves as a "fine" levelling system.
  • a car brake 90 is mounted to the bottom 16 of the casing 12.
  • the car brake 90 engages or disengages the guide rails 104.
  • the car brake 90 opens and closes as the standard brake during normal service and also closes as a standard safety gear during emergency situations.
  • the support position system 60 is connected with the car position system 110 and/or car control unit 120, and/or main electric drive / frequency converter 130 and/or main elevator controller 140.
  • a damping unit (not shown) can be integrated into the support levelling system 30.
  • an accelerometer (not shown) can be incorporated to or linked to the support drive control 50.
  • the elevator system described above allows using lighter, more elastic traction belts 109 also for higher travelling heights. Furthermore, as the car brake 90 serves as main brake and as a safety gear system, further material and cost reduction is possible. Furthermore, the levelling and relevelling of the support 20 is jerk-free and safer. The landing accuracy increases. In detail, it is not necessary to reopen and close the brake for levelling the support.
