Crane vehicle comprising: - a carrier ; - a slewing base slewably supported on the carrier ; - a boom supported by the slewing base in a derrickable and telescopic manner; - a hook which is suspended from a distal end of the boom with a wire therebetween, and is configured to engage with a hoisted load; - at least one digital camera ; - a storage unit configured to store image data outputted by the digital camera ; and - a controller , characterized in that - the crane vehicle further comprises: - a load detection means for detecting a load being applied to the hook ; - the controller performs - when a predetermined measurement value meets a predetermined condition, a process of recording start which associates the digital camera outputting image data to be stored when the predetermined measurement value meeting the predetermined condition with the relevant predetermined condition and starts storing in the storage unit the image data outputted by the digital camera associated with the predetermined condition, and - a process of storing measurement value to store the predetermined measurement value in the storage unit concurrently with the process of recording start, - the predetermined measurement value represents a load factor which is the ratio of the weight of hoisted load detected by the load detection means to the suspendible maximum weight of the hoisted load, and - the predetermined condition is that the load factor exceeds a predetermined threshold. - a carrier ; - a slewing base slewably supported on the carrier ; - a boom supported by the slewing base in a derrickable and telescopic manner; - a hook which is suspended from a distal end of the boom with a wire therebetween, and is configured to engage with a hoisted load; - at least one digital camera ; - a storage unit configured to store image data outputted by the digital camera ; and - a controller , characterized in that - the crane vehicle further comprises: - a load detection means for detecting a load being applied to the hook ; - a load detection means for detecting a load being applied to the hook ; - the controller performs - when a predetermined measurement value meets a predetermined condition, a process of recording start which associates the digital camera outputting image data to be stored when the predetermined measurement value meeting the predetermined condition with the relevant predetermined condition and starts storing in the storage unit the image data outputted by the digital camera associated with the predetermined condition, and - a process of storing measurement value to store the predetermined measurement value in the storage unit concurrently with the process of recording start, - when a predetermined measurement value meets a predetermined condition, a process of recording start which associates the digital camera outputting image data to be stored when the predetermined measurement value meeting the predetermined condition with the relevant predetermined condition and starts storing in the storage unit the image data outputted by the digital camera associated with the predetermined condition, and - a process of storing measurement value to store the predetermined measurement value in the storage unit concurrently with the process of recording start, - the predetermined measurement value represents a load factor which is the ratio of the weight of hoisted load detected by the load detection means to the suspendible maximum weight of the hoisted load, and - the predetermined condition is that the load factor exceeds a predetermined threshold. <EOS>
