Definitions

  • the present invention relates to an elevator, in particular a traction sheave elevator, with a car guided in a lift shaft and with one Drive machine with assigned control cabinet.
  • Elevators are for example from EP 0 631 968 B1, EP 0 710 618 A2 and EP 0 719 724 A1.
  • the drive unit is completely in the elevator shaft arranged so that no additional machine or engine room is needed.
  • the drive machine is usually located in the upper one or lower part of the elevator shaft between that of the car area required during its movement and a wall of the lift shaft arranged.
  • the control unit of the elevator is corresponding in the door frame of the shaft door of the top or bottom Floor arranged and for maintenance and repair work Can be operated from the floor corridor. Operation of the Control from the floor corridor has the consequence that the Corridor at least partially blocked off during maintenance work must be what, in extreme cases, hinders escape routes leads. Also the maintenance or repair work only possible to a limited extent because the controls are operated from the floor corridor no or only limited Visual contact with the car and therefore none (Sufficient) observation of their driving behavior possible is. A check of the engine while driving Nominal speed is therefore not possible.
  • EP 0 725 033 A1 describes a temporary work space safeguard known, by means of which the penetration of the car in a temporary work space such as the pit of an elevator is avoided.
  • a temporary work space such as the pit of an elevator is avoided.
  • Swivel buffers are provided, which before entering the Shaft pit pivoted into the driving area of the car become.
  • the swivel buffer is preferably by gravity automatically in the limit of the travel path of the car Locking position can be tilted, whereby when activated Swiveling buffer the driving operation of the elevator is interrupted.

This will make the elevator available to the public Public traffic compared to the known elevators without Engine room increased. Furthermore are with repair and maintenance work no more disabilities connected in the floor corridor, because the maintenance personnel are temporarily set up in the elevator shaft Engine room stops and all work from the lift shaft can perform.
  • the lockability of the engine room is particularly achieved in that through the shaft door in particular the top floor accessible temporary engine room after entering closed by the maintenance personnel by closing the shaft door becomes.
