Definitions

  • the present invention relates to a device for controlling the stopping position of an elevator car within a predetermined height tolerance with respect to a floor level according to the preamble of patent claim 1.
  • a technical problem of conventional passenger or goods lifts is that the elevator car in unfavorable traction of the support means or improper use, in particular overload, makes an uncontrolled movement of the floor with an open door.

  • Annex A3: 2009 is in particular a height tolerance to be maintained stop position of the elevator car with respect to the floor level specified. Accordingly, after an uncontrolled movement with an open door, the elevator car must come to a standstill at the latest after 1200 mm distance from the floor level. The upper access edge to the elevator car must be spaced from the floor level by at least 1000 mm if the elevator car is too low or the cabin floor is too high if the elevator car is too high. In addition, there may be at most a clearance of 200 mm in the lower area of the cabin access.
  • Annex A3 2009 therefore requires a recertification of certain safety components and, if necessary, a rebuilding of the existing elevators, which may require substantial new investments.
