  • Fig. 2 shows a sectional view through the measuring device Fig. 1 whereby the measuring device 1 and its structure in the area around the supporting rope 2 to be tested is shown in more detail. Shown are the first part 6 and the second part 7 of the fastening device 4. These two parts 6, 7 each have a clamping jaw 12. These serve as a fixing device 13 for the test cable 2 to be tested. Preferably, the other supporting cables are held in a stationary manner in the measuring device 1 via the fixing device 13. If all supporting cables are fixed in this way, a pair of clamping jaws is preferably provided for each carrying cable. Furthermore, a support rail 14 is provided.
  • a clamping jaw 12 in a specific region of the fixing device 13 relative to a part of the fastening device 4 can be provided.
  • the support traverse limits movement of the jaw 12.
  • Fig. 2 shown is the pair of jaws 12 that is associated with the test cable 2, in a rest position. It is held by a jaw lock 15 in the rest position. If the jaw lock would be opened, at least one of the two, preferably both jaws 12 would be movable and according to gravity move down.

  • This jaw 12 is associated with a support rail 14, which is pivotally connected to a pressure lever 16.
  • the pressure lever 15 is in turn coupled to a pull lever 11. Preferably, these together form a rigid component.
  • a pressure on the pressure lever 15 can now be exercised.
  • the load spindle axis 10 serves as a pivot point about which the pressure lever 15 and the load lever 16 rotate.
  • the load spindle 11 is connected to a measuring device 17, by means of which the force to be applied, a path or another characterizing parameter which is meaningful for the drivability test, can be detected.
  • the measuring device 1 is now used as follows: An inspection and work routine begins with a selection of any supporting rope, which is determined as a measuring cable.

  • the opened mounting device 4 is pushed laterally over the support cables and closed by means of the clamping spindle 8.
  • the respective, not individually illustrated jaws put on the suspension cables.
  • the load transfer takes place successively from the measuring cable into the other carrying cables, preferably until the carrier cable drive pulley connection fails as a static friction connection.
  • the force then measured on the load spindle 11 is a measure of the driving ability of the overall connection.
  • one or more jaw bearings 18 are provided. Preferably, these are designed as sliding or roller bearings.
  • Fig. 3 shows a schematic view of an arrangement of a measuring device with four support cables 3 and one of them to be tested support cable 2.
  • the measuring device is able to cover all supporting cables of the traction sheave elevator. By selectively clamping as described above, each individual suspension rope can be checked one after the other.
  • the advantage here is a simultaneous examination of several supporting pages and thus a shortening of the examination time.
  • Fig. 4 shows a schematic view of a further embodiment and arrangement of a measuring device 1.
  • the measuring device 1 has a fastening device 4 for three of the five test cables to be tested. Basically, any number of three selected suspension cables can be taken into account, regardless of a total number of suspension cables. This allows a very lightweight design and facilitates handling of the measuring device 1 when mounting. If, for example, there are five carrying ropes and the measuring device comprises three carrying ropes, then three carrying ropes are tested in each case.
  • the measuring device is arranged so that there is an unchecked suspension rope between two tested suspension cables. By knowing the tested ropes can then be closed with knowledge of the overall behavior of the suspension ropes on the individual previously untreated suspension cable.

  • a transmission may be provided, the translation enables a fine transmission of the movement.
  • a clamping force can be carried out by an independent application of the jaws to one or more support cables due to a relative movement of the jaws to the support cable.
  • a power transmission can take place.
