Definitions

  • the present invention relates to an aerial work platform with a Telescopic boom and one at one end of the telescopic boom Work basket, with a leveling of the work basket compared to the Telescopic boom using at least one hydraulic master-slave cylinder system he follows.
  • the invention further relates to a method for Control of the leveling of a work platform opposite an aerial work platform a telescopic boom, at one end of which the work cage is attached.
  • Such aerial work platforms and methods are known. This is how DE 34 describes it 46 491 C2 an aerial work platform with hydraulic leveling device at the an inclinable boom pivotable relative thereto an articulated Working platform is arranged with a leveling device.
  • the leveling device includes a hydraulic cylinder connected to the work platform Safety valves and a reserve auxiliary pump that can be connected to it Hydraulic fluid.
  • the leveling device has the task, regardless of the respective inclination of the boom the work platform for the safety of it keep people horizontal, with a maximum incline of 5 ° is permitted relative to the horizontal plane.
  • DE 100 32 423 also describes A1 a mobile aerial work platform with one arranged on a chassis Boom structure, the boom structure being movably attached to a turret is.
  • the well-known aerial work platform has a leveling tower which a boom structure is movably attached.
  • a second inclination sensor can be attached to the chassis be arranged.
  • the well-known aerial work platform serves to improve the Stability of mobile aerial work platforms.
  • a disadvantage of the known aerial work platforms with telescopic boom is, however, that with larger aerial work platforms when the telescope is extended a certain Deviation from the ideal position, i.e. the zero position, arises because of the deflection of the telescopic boom due to the well-known hydraulic leveling can be intercepted.
  • It is therefore an object of the present invention to provide an aerial work platform provide the type mentioned above, which is a simple and safe Additional leveling or fine leveling of the work basket compared to the Telescopic boom enables.
  • Another object of the present invention is a method for control leveling a work platform of an aerial work platform in relation to one Telescopic boom with the work cage attached to one end, to provide, which a simple and safe additional leveling or Fine leveling of the work basket compared to the telescopic boom enables.
  • an aerial work platform with a telescopic boom and a working cage arranged at one end of the telescopic boom is on the Work basket at least one inclination sensor for detecting the inclination of the Work basket arranged opposite the horizontal H and / or the vertical V, the inclination sensor via a signal or data line with an evaluation and control unit is connected, and the evaluation and control unit in Dependence on the signals or determined data of the inclination sensor Control signals transmitted to a hydraulic master-slave cylinder system, such that the work cage is independent of the inclination of the telescopic boom using the master-slave cylinder system in approximately horizontal and / or vertical alignment is maintained.
  • the electrical system of the Tilt sensor and the evaluation and control unit works as it were Auxiliary system for the main hydraulic leveling system, namely the master-slave cylinder system.
  • a second inclination sensor for detecting the inclination of the telescopic boom arranged.
  • the second inclination sensor is also via a signal or Data line connected to the evaluation and control unit. That is it possible, on the one hand the inclination of the telescopic boom and on the other hand the Determine misalignment of the work basket and correct it in such a way that both the telescopic boom and the work basket of the zero position, that is, without larger deviations from the horizontal or vertical is maintained.
  • the first Inclination sensor and / or the second inclination sensor and / or the evaluation and Control unit when a predefined inclination of the work cage is exceeded and / or the telescopic boom a signal to switch off the aerial work platform and / or a warning signal.
  • a method for controlling the leveling of the work basket an aerial work platform opposite a telescopic boom, at one end the work cage is attached includes the following steps: (a) extending the Telescopic boom and rough leveling of the work basket using at least one hydraulic master-slave cylinder system; (b) detecting the inclination of the Work basket in relation to the horizontal H and / or the vertical V by means of at least one tilt sensor arranged on the work cage; (c) submission the signals or data determined by the inclination sensor by means of a signal or data line to an evaluation and control unit; (d) Control the hydraulic master-slave cylinder system with the help of the evaluation and Control unit depending on the signals or determined data of the Inclination sensor, such that regardless of an inclination of the Telescopic boom of the work basket using the master-slave cylinder system in is held approximately horizontally and / or vertically.
  • the evaluation and control unit signals or data of a Telescopic boom arranged second inclination sensor for detecting the Inclination of the telescopic boom transmitted.
  • the first inclination sensor and / or the second inclination sensor and / or the Evaluation and control unit when exceeding a predefined inclination of the Work basket or the telescopic boom a signal to switch off the Aerial work platform and / or a warning signal.
  • Figure 1 shows a schematic representation of a telescopic boom 12 with a Work basket 16 of an aerial work platform 10 according to the prior art. you recognizes that the leveling of the basket 16 relative to the Telescopic boom 12 a hydraulic master-slave cylinder system 18 between the elements mentioned is arranged. Furthermore you can see that conditionally by the length of the telescopic boom 12, this has an orientation that clearly from the ideal horizontal position H and / or the ideal vertical position V. differs. Define the ideal horizontal position H and the ideal vertical position V. the so-called zero position. From Figure 1 it is clear that the master-slave cylinder system is not able to be caused by the deflection of the Telescopic boom 12 deviated from the zero or ideal position without to compensate further data or information.
  • FIG. 2 shows a schematic representation of a telescopic boom 12 with a Work basket 16 according to an embodiment of the invention Aerial work platform 10.
  • an inclination sensor 20 is on the work basket 16 Detecting the inclination of the work basket 16 with respect to the horizontal H and / or the vertical V arranged.
  • the inclination sensor 20 is connected via a signal or data line with an evaluation and control unit (not shown) connected, the evaluation and control unit depending on the Corresponding signals or determined data of the inclination sensor 20 Control signals transmitted to the master-slave cylinder system 18 such that regardless of the inclination of the telescopic boom 12 of the work basket 16 by means of the master-slave cylinder system 18 in approximately horizontal and / or vertical alignment is maintained.
  • the system works to a certain extent as an auxiliary system to the main hydraulic leveling system, namely the master-slave cylinder system 18. In contrast to pure electronic leveling systems that works in the embodiment shown leveling system even if the programmed Control of the system has failed and the aerial work platform 10 via a Emergency operation is operated.
  • the aerial work platform 10 can be moved be trained.
