WORK MARCHINE WITH OPERATOR'S CABIN

摘要

Rear portions of an cab body (11) are resiliently supported by a rubber mount (13), while front portions of the cab body (11) are supported by a spring mount (23) with a smaller spring constant than that of the rubber mount (13). This lowers the pitching vibration transmission rate from a revolving frame (4) to the cab body (11), in addition to attenuation of pitching by an oil damper (25) provided in the rubber mount (13). Besides, bouncing and rolling movements of the cab body are converted into pitching movements and finally attenuated.
