Abstract
Official abstract text for this publication.
A crane comprising a traveling body and a turning body turnably supported by the traveling body, the crane performing power feeding and communication between the traveling body and the turning body. The traveling body is provided with: a power supply; a lower controller which controls the traveling body and transmits power to the devices included in the traveling body; and a lower transmitter-receiver which wirelessly transmits and receives the power and data signal from the power supply. The turning body is provided with: an upper controller which controls the turning body and transmits power to the devices included in the turning body; and an upper transmitter-receiver which wirelessly transmits and receives the power and data signal to and from the lower transmitter-receiver.
First claim
Opening claim text (preview).
The invention claimed is: 1. A crane, comprising: a traveling body including first devices that serve to allow the traveling body to travel; and a swivel body swivelably supported on the traveling body and including second devices for achieving crane work, wherein: power feeding and communication are performed between the traveling body and the swivel body, the traveling body includes a power supply device, a lower transmission and reception device for feeding electrical power from the power supply device to the swivel body and for transmitting and receiving a data signal to and from the swivel body, and a lower controller that receives detected signals from the first devices and controls the first devices and the traveling body, and transfers the electrical power from the power supply device to the first devices and the lower transmission and reception device, the swivel body includes an upper transmission and reception device for receiving the electrical power fed from the lower transmission and reception device and for transmitting or receiving the data signal to or from the lower transmission and reception device, and an upper controller that receives detected signals from the second devices and controls the second devices and the swivel body and transfers electrical power received by the upper transmission and reception device to the second devices, and the receiving and feeding of the electrical power and the transmitting and receiving of the data signal between the lower transmission and reception device and the upper transmission and reception device are performed wirelessly. 2. The crane according to claim 1 , wherein the lower transmission and reception device and the upper transmission and reception device are disposed at a center around which the swivel body swivels. 3. The crane according to claim 1 , wherein the electrical power and the data signal are simultaneously transferred between the upper transmission and reception device and the lower transmission and reception device by feeding or receiving the electrical power by an electromagnetic induction method or a magnetic field resonance method and by superimposing the data signal on the electrical power. 4. The crane according to claim 1 , wherein the electrical power and the data signal are separately transferred between the upper transmission and reception device and the lower transmission and reception device via separate antennas by feeding or receiving the electrical power by a microwave power feeding method.
