Positioning mechanism, especially for timber machinery drivers cabin, includes pivotable hinge arms between articulation points on main and auxiliary frames

摘要

The mechanism comprises two articulation points (1, 2) coupled to the main machine frame and two further articulation points (3, 4) indirectly coupled to an auxiliary frame (AF1) used for mounting the cabin. Hinge arms (5, 6) are coupled to the four articulation points. A device (7) positioned between the arms and main frame is used to pivot these arms in order to control cabin position.
