CRANE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/208283
Kind Code:
A1
Abstract:
[Problem] To provide a crane vehicle that achieves safe movement by reliably detecting an area which is a blind spot from a driver's seat, namely, an obstacle on the opposite side from the driver's seat across a boom. [Solution] This crane vehicle comprises an obstacle sensor which is a transmission/reception antenna that transmits a detection wave and receives the detection wave reflected from the obstacle. A signal corresponding to the reflected wave received by the obstacle sensor is amplified and input to a controller. The controller calculates the position and size of the obstacle on the basis of the signal (S12). The controller generates an obstacle display image (S16 to S18) comprising a vehicle object that represents the crane vehicle 10 and an obstacle object corresponding to the calculated size of the obstacle and disposed at a position corresponding to the calculated position of the obstacle, and displays the generated obstacle display image on a display.
