<p><P>PROBLEM TO BE SOLVED: To provide an abnormal operation detector allowing a worker to infer an overload operation condition of a hydraulic excavator based on the amount of hydraulic operation. <P>SOLUTION: This abnormal operation detector computes amount of adding-up of amount of operation by an integral amount computing means in accordance with amount of operation of each operation mechanism obtained by an operation pressure detecting means, computes amount of operation fluctuation by a fluctuation amount computing means, and allows the worker to infer joint angles of each operation mechanism based on the integral amount and determine the overload operation condition by using an abnormal operation determining means based on the inferred joint angles and the amount of operation fluctuation. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
