TILTING CAB MECHANISM FOR A CRANE

摘要

A cab support assembly supports and moves an operator's cab relative to a frame of a construction machine. The cab support assembly includes a cab support coupled to the frame of the construction machine. The operator's cab is mounted to a cab support mounting frame, which in turn is pivotably coupled to the cab support. An actuation device is coupled to the cab support and to the cab support mounting frame. The actuation device includes a first actuation device position in which the cab support frame is in a first position in which the cab support mounting frame defines a first plane, and at least a second actuation device position in which the cab support mounting frame is in a second position such that the cab support mounting frame defines a second plane that intersects the first plane at a negative angle.

主权项

1. A cab support assembly for supporting and moving an operator's cab relative to a frame of a construction machine, wherein said frame is mounted on a carbody of said construction machine and movable ground engaging members mounted on said carbody allow said construction machine to move over the ground, said cab support assembly comprising:
a) a cab support coupled to said frame of said construction machine; b) a cab support mounting frame pivotably coupled to said cab support, said operator's cab being mounted to said cab support mounting frame; and, c) an actuation device coupled to said cab support and to said cab support mounting frame, said actuation device including a first actuation device position in which said cab support frame is in a first position in which said cab support mounting frame defines a first plane, and at least a second actuation device position in which said cab support mounting frame is in a second position such that said cab support mounting frame defines a second plane that intersects said first plane at a negative angle.
