A cab for a machine. The machine has a longitudinal axis extending between a front, and a back opposite to the front. The cab includes a roof and a floor extending generally about the longitudinal axis. A vertical seat index axis extends through intermediate portions of the roof and the floor and is associated with a position of the operator disposed to face the front. The vertical seat index axis intersects perpendicular to the longitudinal axis at an intersection. A plurality of support members are disposed between the roof and the floor, including a rear support member disposed at a rear end of the cab. At least an upper portion of the rear support member is positioned at an angle relative to the intersection at an angle along the longitudinal axis and defines a rear view opening to facilitate rear end visibility of the machine.

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.

A machine including a chassis, in which an engine is supported on the chassis. The engine includes serviceable components which require servicing. A cab is mounted on the chassis, such that the cab is disposed over the engine. The cab includes a roof and a floor, interconnected through the side-walls to define an enclosure. The floor is disposed above the engine. Further, the cab includes a floor opening defined in the floor. An access panel is removably coupled to the floor opening. The floor opening provides an access to the serviceable components by removing the access panel.
