<P>PROBLEM TO BE SOLVED: To eliminate a sense of incompatibility or discomfort for an operator by suppressing generation of vibration by controlling to smoothly stop a working element even if the operator operates an operation lever to rapidly stop the working element. <P>SOLUTION: A control device 30 of an excavator includes an inertia load calculation unit 42 which calculates an inertia load operating upon an actuator on the basis of a detecting signal from a detector, an allowable energy calculation unit 46 which calculates allowable energy on the basis of a manipulated variable of an operation lever, and a control unit 48 which creates a stop pattern on the basis of the inertia load, compares the stop pattern with the lever manipulated variable obtained from the manipulation of the operation lever and controls to reduce inertia energy of a working element along the stop pattern in accordance with a comparison result. <P>COPYRIGHT: (C)2012,JPO&INPIT |
