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.

A cab for a power machine, the cab comprising:
- a cab frame forming an operator compartment and having a first side wall, a second sidewall, a front, a rear, a top and a bottom;
- a cab door configured to cover an opening in the front of the cab frame when in a closed position;
- and
- a first four-bar linkage coupled to the cab frame and the cab door, wherein the first four-bar linkage is configured to define a path of movement for and support the cab door as the cab door moves between the closed position and an open position, wherein in the open position the cab door is positioned overhead of an operator seat beneath the cab top.
A cab for a power machine, the cab comprising:
- a cab frame forming an operator compartment and having a first side wall, a second sidewall, a back, and a top;
- a cab door configured to cover an opening in the front of the cab frame when in a closed position;
- 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 between an operator seat and one of the first and second side walls of the cab frame.
A cab for a power machine, the cab comprising:
- a cab frame forming an 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;
- 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 pivotally mounted to the cab door and to the cab frame and 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.
A cab for a power machine, the cab comprising:
- a cab frame forming an 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;
- and
- a first latch positioned on the cab door;
- a first complementary mechanism coupled to the cab frame and configured to engage the first latch when the cab door is in the closed position;
- and
- a second complementary mechanism coupled to the cab frame and configured to engage the first latch when the cab door in in the open position.
A cab for a power machine, the cab comprising:
- a cab frame forming an operator compartment and defining an opening;
- a cab door mounted to the cab frame and configured to be moved between closed and open positions and to cover the opening in the cab frame when in a closed position;
- a first seal on a first portion of the cab door configured to engage a first portion of the cab frame when the door is in the closed position;
- a second seal on a second portion of the cab frame configured to engage a second portion of the cab door when the door is in the closed position.
