Document Type and Number:
WIPO Patent Application WO/2019/208282
Kind Code:
A1
Abstract:
[Problem] To provide a crane truck capable of reliably detecting an obstacle in a blind spot area from a driver's seat, more specifically, on the opposite side of the driver's seat across a boom, so as to ensure safe movement. [Solution] A crane truck 10 is provided with obstacle sensors 50A, 50B, and 50C, which correspond to transceiving antennas, for transmitting detection waves and receiving a detection wave reflected from an obstacle. The obstacle sensor 50A is provided on a lower surface of a distal end portion of a boom 32 and transmits detection waves to an area ahead of the crane truck 10 and an area on the left side of the crane truck 10. The obstacle sensor 50B is provided on an upper surface of a left end portion of the vehicle body 20 and transmits a detection wave to an area on the left side of the crane truck 10. The obstacle sensor 50C is provided on an upper surface of a rear end portion of the vehicle body 20 and transmits detection waves to an area behind the crane truck 10 and an area on the left side of the crane truck 10. A signal corresponding to the reflected wave received by the obstacle sensors 50A, 50B, and 50C is amplified and input to a controller.
