WORKING MACHINE CONTROL DEVICE FOR A CONSTRUCTION

摘要

A construction machine comprising a first boom (1) rotatably mounted on a vehicle frame, a second boom (4) rotatably mounted on said first boom, a first boom cylinder (2) for connecting said vehicle frame (3) to said second boom (4) and a second boom cylinder (5) for connecting said second boom (4) to said first boom (1), wherein a target value at a leading end of a working machine is coordinate transformed into target angles of said first and second boom angles, wherein a target cylinder length of said first boom cylinder (2) is obtained from the coordinate transformed target angles of said first and second boom angles, and wherein said first boom cylinder (2) is driven based on this target cylinder length, whereby it is possible to simply and accurately drive and control each working machine of a new link mechanism by designating a position or a speed at a leading end of said each working machine.
