摘要： PROBLEM TO BE SOLVED: To provide an interference preventive device for a construction machine, capable of continuing work while preventing interference between a working tool and a driver's cab, even when an angle sensor or the like for detecting a turning angle of the working tool is troubled.
SOLUTION: A trouble detecting means 34 monitors an output from the working tool angle sensor 22 for detecting the turning angle of the working tool and for detecting the trouble. Interference preventive control by the first interference preventive control means 43 is switched to interference preventive control by the second interference preventive control means 46, by detecting the trouble of the angle sensor 22 by the trouble detecting means 34. The first interference preventive control means 43 conducts the interference preventive control referring to not only a turning angle of a joint part of an articulated front but also the turning angle of the working tool. The second interference preventive control means 46 conducts the interference preventive control not referring to the turning angle of the working tool.
