Abstract
An HVAC system for a power machine can include a housing configured to be supported on a front frame member of the power machine forward of an operator enclosure. A ductwork section can be connected to the housing and direct air from the housing to a front opening in the operator enclosure.
Claims20
A power machine comprising:
- an articulated frame with a front frame member and a rear frame member, the front frame member being configured to pivot relative to the rear frame member;
- an operator enclosure supported on the front frame member, the operator enclosure being configured to pivot with the front frame member relative to the rear frame member and including an enclosure frame and an operator station that is at least partly enclosed by the enclosure frame;
- a lift arm structure arranged forward of the operator enclosure and configured to move relative to the front frame member under power, with first and second lateral portions of the operator enclosure being defined on opposing lateral sides, respectively, of a path of travel of the lift arm structure;
- and
- a heating, ventilating, and air conditioning (HVAC) system that includes:
- an HVAC housing that is supported on the operator enclosure at least partly forward of the operator enclosure;
- a blower fan within the HVAC housing;
- and
- a rigid ductwork section arranged to direct air from the blower fan along a flow path from the HVAC housing to a front opening in the operator enclosure;
- the flow path extending on only the first lateral portion of the operator enclosure;
- and
- the rigid ductwork section not including any portion of the enclosure frame.
