Problems solved by technology
In addition, construction machinery components are often also stored in storage locations for extended periods of time, for example over winter, which further wears down the batteries of such transponder chips
[0012] In addition to the power supply problems mentioned above, there are also problems with information transmission when, for example, there is mutual interference of radio signals due to a large number of RFID chips or there is environmental interference
Especially for RFID tags mounted on steel components, it is often not simple to keep the communication stable

Embodiment Construction
[0047] Such as figure 1 As shown, the construction and / or material handling machine 11 may be designed as a crane (for example, in the form of a rotating tower crane) and may include a plurality of construction elements 12 from which the construction and / or material handling machine 11 may be constructed . In general, the building elements 12 here can be variably arranged and / or mounted in different positions so that the machine can operate in different configurations depending on the presence, number and mounting positions of the building elements 12 .
[0048] Such building elements 12 may in particular be mechanical structural components, such as steel components, stay cables, ballast weights or the like. In the case of a crane, the construction element 12 may for example comprise jib parts and / or tower parts from which the jib 13 or tower 14 of the crane may be assembled. Depending on the type of crane, they can be, for example, lattice girders Telescoping panels or to...

The invention relates to a method and a device for detecting the construction state of a construction and / or material handling machine (11), in particular a crane, and / or the position of individual construction elements (12) of a construction and / or material handling machine, the device comprises an electronic identification element (1) mounted on a construction element of the construction and / or material handling machine and an electronic evaluation device (23) for determining the construction state and / or the position of the construction element from information received from the identification element. An identification element mounted on the building element is provided with an energy harvesting device (10) for harvesting electrical energy from environmental influences and an energy store (7) for storing the harvested energy and supplying power to the identification element.
Description
technical field [0001] The invention relates to a method and a device for detecting the construction state of a construction and / or material handling machine, in particular a crane, and / or the position of individual construction elements (Rüstelemente) of a construction and / or material handling machine, construction and / or material The handling machine comprises an electronic identification element mounted on a construction element of the construction and / or material handling machine and an electronic evaluation device for determining the construction status and / or the position of the construction element on the basis of information received from the identification element. The invention also relates to such a construction and / or material handling machine, in particular in the form of a crane. Background technique [0002] Not only construction and / or material handling machinery such as cranes (e.g. rotating tower cranes or telescopic boom mobile cranes), but also mast or of...
