WORK MARCHINE WITH OPERATOR'S CABIN

Document Type and Number:

WIPO Patent Application WO/1997/046766

Kind Code:

A1

Abstract:

A rear side of an operator's cabin body (11) is resiliently supported by a rubber mount (13), and a front side of the operator's cabin body (11) is resiliently supported by a spring mount (23), of which a spring constant is set to be smaller than that of the rubber mount (13). Accordindly, a vibration transmissibility of pitching transmitted from a revolving frame (4) to the operator's cabin boby (11) can be kept small, and pitching is damped by an oil damper (25) which constitutes the rubber mount (13). Further, bounce and rolling transmitted to the operator's cabin body (11) are converted into pitching for attenuation of vibration.
