PROBLEM TO BE SOLVED: To provide a bucket warning device capable of improving the safety of a worker at the time of hoisting and moving a bucket. SOLUTION: The bucket warning device installed on the bucket 10 hoisted by a construction machine such as a crane is equipped with a height detection device 1 for detecting a height from the ground G when the bucket 10 is hoisted, and an alarm 2 interlocking with the height detection device 1 for giving an alarm when the bucket 10 comes to a predetermined hoisting height. By such a bucket warning device, the alarm is given from the bucket itself which moves overhead. Thus, the alarm can easily be heard by a worker who works on a passing route of the bucket, and then the worker can look out an upper part. COPYRIGHT: (C)2009,JPO&INPIT
