Abstract

Mobile or stationary working apparatus, in particular a working vehicle, with at least one telescopic extension arm (3) which has two or more extension arm elements (31, 32, 33) which can be moved in relation to one another, with detection means being provided on the extension arm elements (31, 32, 33) and also on a base station, in particular a rotatable trailer of the working vehicle, for detecting the position of the extension arm elements (31, 32, 33) in relation to one another and with respect to the base station, with provision being made, according to the invention, for the detection means to be in the form of radio detection means, with a radio base unit (8) being arranged on the base station and further transponder units (10, 12) being arranged on the extension arm elements (32, 33).

Claims

1. A mobile or stationary piece of equipment comprising:

a base;

at least one telescoping arm carried on the base and having two or more telescoping parts that can move relative to each other; and

a detection system on the telescoping parts and on the base for detecting the positions of the telescoping parts relative to each other and relative to the base the detection system being a radio detection means and including a radio base unit mounted on the base and transponders mounted on the telescoping parts.

2. The mobile or stationary equipment according to claim 1 wherein the radio detection means are designed as RFID units.

3. The mobile or stationary equipment according to claim 1 wherein the transponders are mounted on ends of the telescoping parts.

4. The mobile or stationary equipment according to claim 1 wherein the transponder is mounted on the first telescoping arm part on its end remote from the end of the non-telescoping arm part.

5. The mobile or stationary equipment according to claim 1 wherein the radio base unit is mounted on a semitrailer of the equipment.

6. The mobile or stationary equipment according to claim 1 wherein the radio base unit or the transponders have their own power supply.

7. The mobile or stationary equipment according to one of the previous claims wherein the radio base unit or the transponders are designed for power supply via radio.

8. The mobile or stationary equipment according to claim 1 wherein the radio base unit or the transponders are designed for data transmission with other radio base units or other transponders of further mobile or stationary pieces of equipment.
