Definitions
- the invention relates to a method for synchronous telescoping in and out several booms of a crane having telescopic sections, preferably Mobile crane according to the preamble of patent claim 1.
- the object of the invention is to provide a method for synchronous input and output Telescopic out of a boom having several telescopic sections Specify cranes with which during the entire telescopic process continuously a defined maximum load of the respective extension length can be assigned and asynchrony is avoided.
- the proposed method uses a pilot control an electrical signal is given to an input of control electronics.
- This The signal serves as the setpoint for the telescopic speed of the guide roller adopting telescopic cylinder or step.
- the actual value for the current one The position of the telescopic cylinder or steps is reported to the control electronics.
- the Control electronics make a comparison between the actual value of the Leading role of the telescopic cylinder or stage and the actual value of the telescopic cylinder or steps to be controlled.
- the telescopic speed of the other telescopic cylinders or Levels increased or decreased until all telescopic cylinders were synchronized or stages takes place.
- An electrical signal (e.g. 0-10 V, 0-20 mA Potentiometric, 7-8) to an input of control electronics A1.
- This Signal serves as a setpoint for the telescopic speed and possibly also for Detection of the telescopic direction.
- other signals such as. B. Engine speed or overdrive button influence the telescopic speed to have.
- the telescopic direction can also be via one in the pilot control transmitter A2 built-in direction button can be recognized.
- the feedback on the The current extension position of the telescopic cylinder follows via the length sensor B1, B2 etc., which report a corresponding electrical signal to the control electronics.
- the control electronics now control according to the signals of the pilot control and Length sensor via proportional valves Y1.1, Y2.1, .... or Y1.2, Y2.2 Telescopic cylinder of the boom, the speed of the movement over the control current of the proportional valves is regulated.

Description
Claims (2)
- Verfahren zum synchronen Ein- und Austeleskopieren eines mehrere Teleskopschüsse aufweisenden Auslegers eines Kranes, vorzugsweise Fahrzeugkranes, mittels eines hydraulisch angetriebenen mehrstufigen Teleskopierzylinders oder mehrerer parallel betreibbarer einstufiger Teleskopzylinder,
dadurch gekennzeichnet, daß über einen Vorsteuergeber ein elektrisches Signal auf einen Eingang einer Regelelektronik gegeben wird, das als Sollwert für die Teleskopiergeschwindigkeit eines die Führungsrolle übemehmenden Teleskopierzylinders bzw. Stufe dient und der Ist-Wert für die aktuelle Position der Teleskopzylinder bzw. Stufen der Regelelektronik gemeldet wird und diese einen Abgleich zwischen dem Ist-Wert des die Führungsrolle übernehmenden Teleskopzylinders bzw. Stufe und dem Ist-Wert der zu regelnden Teleskopierzylinder bzw. Stufen macht und im Falle der Feststellung einer unzulässigen Abweichung die Teleskopiergeschwindigkeit der übrigen Teleskopzylinder erhöht oder erniedrigt wird, bis ein synchrones Teleskopieren aller Teleskopzylinder bzw. Stufen stattfindet. - Verfahren nach Anspruch 1,
dadurch gekennzeichnet, daß bei Feststellung einer Nichtsynchronstellung der Teleskopzylinder bzw. Stufen beim Austeleskopieren unter Last das weitere Austeleskopieren gestoppt wird und solange einteleskopiert wird, bis die Synchronstellung wieder erreicht ist.
