A cabin for a machine is disclosed. The cabin may include a floor, a roof, at least one A-post located at a leading end relative to a forward travel direction of the machine, and a C-post located at a trailing end opposite the at least one A-post. The C-post may have first terminal ends located at the floor and second terminal ends located at the roof. The C-post may include a C-shaped beam having the first terminal ends, and a Y-shaped beam structure having the second terminal ends. The Y-shaped beam structure may extend from the C-shaped beam to the roof. The Y-shaped beam structure may include two spaced beams.

Motor grader

An operator cab for a machine such as a motor grader includes an access door coupled to a frame by way of a hinge mechanism. The hinge mechanism has abutting cam and follower surfaces with geometry to control the swinging of the access door such as under the force of gravity. The cam surface has a double-sloped profile of rotation about the pivot axis of the hinge mechanism so that the access door swing is controlled in either of a first or a second swing direction toward a dwell location of the access door.

A roof for a cab of a machine includes a roof surface with a rearward incline having a front portion higher than a rear portion. The roof surface has a recessed portion at the rear portion that receives a Heating Ventilation and Cooling (HVAC) unit. The recessed portion includes a rearward facing sidewall with a rearward incline, such that an upper end of the rearward facing sidewall is closer to the front portion than a lower end. The rearward facing sidewall has a lateral opening, a pair of lateral sidewalls, and a base with a rearward incline, such that a front end of the base is higher than a rear end. The base has an upright opening with a ridge protruding upward, defining a perimeter of the upright opening. The rearward facing sidewall, the pair of lateral sidewalls, and the base, define a contiguous peripheral portion of the recessed portion.

HVAC integrated roof for operator cabs

A cabin is disclosed for use with a mobile machine. The cabin may have a floor and a roof. The cabin may also have at least one A-post located at a leading end relative to a forward travel direction of the mobile machine, and a C-post located at a trailing end opposite the at least one A-post. The C-post may have two terminal ends located at the floor, and a single terminal end located at the roof.
