Abstract
A locking mechanism to prevent accidental lowering of a tiltable operator's cab of an earthmoving vehicle. The locking mechanism includes an elongate rod secured to one end of the cab for movement therewith and a latch. The latch is resiliently urged toward a locked position, but is prevented from moving thereto by blocking engagement with the side of the rod, until a selected tilted position is reached, and a free end of the rod is aligned with the latch. Upon alignment, the latch automatically springs to its locked position underlying the end of the rod thereby preventing downward movement of the rod and the cab supportable thereby. The one end of the rod is mounted to the cab for pivotal movement relative thereto about an axis substantially coincident with that of a pivotal mount for a hydraulic ram energizable to raise the cab.
