Supporting structure of an operator cab for a work machine

摘要

Provided is a supporting structure for an operator cab on a body frame of a work machine, having a floor frame, an operator cab being mounted on said floor frame, said floor frame having a low floor portion and a high floor portion spaced longitudinally from each other at a forward location and a rearward location in a side view, and a vibro-isolating support means being provided between said low and high floor portions and said body frame so as to support the operator cab resiliently. At least one of said vibro-isolating support means located at either of the low floor portion having a support axis (M-M) or the high floor portion a having support axis (N-N) inclines longitudinally at a predetermined angle (theta) from a vertical axis toward the center of gravity (G) of the operator cab. And also while either one of said vibro-isolating support means is located at the low floor portion and the high floor portion having a vertical support axis, another vibro-isolating support means have a support axis which inclines longitudinally at a predetermined angle (theta1) from a vertical axis and also laterally at a predetermined angle (theta2) from a vertical axis toward the center of gravity (G) of the operator cab.
