  • the engine brake can be pulled by pulling the operating handle be opened. If between the weight of the occupied Elevator car and its counterweight no balance there is, the elevator car will because of the existing Imbalance moving up or down put. Requirement that the elevator car does not performing uncontrolled rapid movement is a generator operating function the drive machine in emergency operation, in which the motor windings are short-circuited.
  • the locking means can with a Interact with buttons that are firmly connected to the elevator car and the altitude of the elevator car within the Can capture elevator shaft. As soon as this button is one Elevation of the elevator car determines in which the elevator doors for easy exit on one floor can be opened, the opening position of the Brake guarantee locking of the emergency exemption means by in particular one directly connected to the button Actuator canceled. Then they are in the elevator car leading emergency relief devices back in their for the activation of a new emergency exemption predetermined starting position.

  • Two pulleys 11 and 12 are adjacent in a common plane with the traction sheave 6 on the roof of the cabin 1 two pulleys 11 and 12 provided. Both pulleys 11 and 12, through which Elevator rope 2 once in the direction of the rope and once behind the traction sheave 6 are attached - but with reference to the width of the elevator car to the same side of the drive machine 7 - are lifted around by 2 below entwined.
  • the diameter size or height arrangement the deflection rollers 11, 12 is such that the elevator rope 2 without crossing the traction sheave 6 to and from it again can be dissipated. Runs over the deflection roller 11 the elevator cable 2 directly to a fixed link in the elevator shaft. The elevator cable runs from the deflection roller 12 2 via a fixed in the elevator shaft Deflection roller 13 over another, attached to the counterweight 3 Deflection roller 5 to a second fixed linkage in the elevator shaft.
  • This elevator rope guide runs the elevator rope both in the traction sheave 6 and at least in the pulleys 11, 12 of the elevator car 1 - relatively to each other - each in a straight line.
  • FIG. 4 An alternative guidance of the elevator rope 2, in which the Elevator rope 2 wraps around traction sheave 6 by at least 270 °, is shown in Fig. 4.
  • the drive machine 7 with the traction sheave 6 is in turn in a side Edge area of the roof of the elevator car 1.
  • a deflection roller 12 ' is arranged at the edge of the elevator car roof. That of a fixed linkage in the head area of the elevator shaft downward elevator rope 2 wraps around the traction sheave 6 by at least 270 ° and runs then in the lower area of the opposite Cab edge attached pulley 12 ', from the it as in the embodiment of FIG.
  • the elevator car is a central suspension of the elevator car 1 given.
  • the rope guide is located above the elevator car 4 no deflection roller above the elevator car, which is desirable for security reasons and sometimes even is required.
  • the drive machine 7 is control engineering with the also on the vehicle cabin 1 fixed electronic central unit 10 connected.
