<P>PROBLEM TO BE SOLVED: To provide a cab mount control device capable of keeping good operability even when pitching is generated on a cab, a cab mount method, and a construction machine. <P>SOLUTION: The cab mount control device 50 for a variable attenuation cab mount 30 that supports the cab of the construction machine at four points is composed of an acceleration sensor 51 detecting state variation in the cab 3, a state quantity estimating means 56 for estimating the state quantities of pitching, rolling, and in the vertical direction on the basis of the detection result by the state variation detecting means 51, and an attenuation force calculating means 57 for calculating attenuation force generated at on the basis of the estimated result by the state quantity estimating means 56. The attenuation force calculating means 57 calculates, at least when the cab is swung in the forward/backward direction, attenuation force of two cab mounts 30 supporting the front side of the cab 3 to be greater than attenuation force of two cab mounts 30 supporting the rear side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
