<p><P>PROBLEM TO BE SOLVED: To prevent operational errors of operation levers, unintended by an operator, without impairing the operability of a work machine having the plurality of operation levers. <P>SOLUTION: The work machine includes a pair of carriages, at least one work front, and a cab on which the operator rides. In the cab, operation devices 50a, 50b are arranged. The operation devices have first operation levers 300a, 300b for operating one actuator out of a group of actuators constituted by the work front and the undercarriages, and second operation levers 54a, 54b for operating one actuator out of the actuators excluding the actuator operated by the first operation lever, respectively. A control device 400 is provided for making the dead zone of the second operation lever larger than the dead zone of the first operation lever when determining that the first operation lever is in operation. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
