<P>PROBLEM TO BE SOLVED: To provide a work machine that grasps the posture of a scraping cutter frame to control the posture as desired so that the scraping cutter frame does not deviate from a prescribed range projected from the vehicle progress direction, against the intention of an operator so as to prevent unexpected movement of the scraping cutter frame and enhance the safety. <P>SOLUTION: A work machine 100 movably supports a scraping cutter frame 20 supporting a scraping cutter 23 which scrapes a ballast supporting a sleeper 5 through a scraping claw 24. The work machine 100 is constituted to include a control device that acquires the actual driving amount of driving actuators 30,50,60,70 for relatively moving the scraping cutter frame 20 and that acquires the posture of the scraping cutter frame 20 based on the acquired actual driving amount so as to control movement of each driving actuator so that at least one part of the scraping cutter frame 20 does not deviate from a prescribed control range. <P>COPYRIGHT: (C)2012,JPO&INPIT |
