Abstract

PROBLEM TO BE SOLVED: To reduce noise to give no unpleasant feeling to an operator by preventing generation of alarm by interference alarming means when a structure on the side of a boom is in a retracted state. SOLUTION: Since a structure on the side of a boom which is in a retracted state, at the time of start of operation, is so close to a structure on the side of a vehicle that there is a danger of interference, posture detection means 20 detects it, and according thereto comparison means 26 determines that entering in an interference danger region stored in danger region storing means 25 is made, then a danger informing signal is output. In this condition, however, since a boom rest supports a lower surface of the boom, the retracted condition of the boom is detected by boom retract condition detection means 32 and a length detector 23 and the retracted condition of a platform is detected by a turning position detector 24. Then, alarm generation preventing means 33 works when retract condition detection means 31 detects the retracted condition while the comparison means 26 outputs the danger informing signal prevents generation of alarm from interference alarm means 27. Similar operation is made when the structure on the side of boom is in the retracted posture in the case of retracting.
