Abstract
Disclosed are front entry cabs, and power machines with front entry cabs, having a door that is moveable between opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat and below a top of the cab. A linkage system defines the travel path of the door between closed and opened positions. The linkage system is configured to minimize interference with operator visibility.
Claims16
A cab for a power machine, the cab comprising:
- a cab frame forming an operator compartment;
- an operator seat positioned within the operator compartment;
- a cab door configured to be moved between closed and open positions and to cover an opening in the front of the cab frame when in a closed position, the opening configured for ingress and egress of an operator moving into and out of the operator compartment;
- and
- a door mounting structure configured to couple the cab door to the cab frame and to define a path of movement for the cab door between the closed position and an open position, wherein in the open position the cab door is positioned inside of the operator compartment overhead of an operator seat, the door mounting structure comprising a linkage including a first link pivotally mounted at a first end to the cab door by a first bracket and pivotally mounted at a second end to the cab frame at a position rearward of the front of the cab frame and rearward of at least a portion of the operator seat, the door mounting structure further comprising a pair of supports mounted to the cab frame along a top of the operator compartment, wherein the linkage urges the cab door into a horizontal position as the cab door slides with respect to the pair of supports to move the cab door from the closed position to the open position.
