Enclosed cab system for mining equipment
First Claim
1. An operator cab for a shuttle car having a drive mechanism for moving the shuttle car within a mine and a bed for loading and unloading material to be transported, the operator cab comprising:
- a cab frame defining an interior chamber positioned laterally relative to the bed and the drive mechanism, the cab frame defining an opening;
a front window assembly including a pane, a latch, and a pane seal, the front window assembly removably coupled to the cab frame such that, when the latch is in a closed position, the pane covers the opening and encloses the interior chamber and the pane seal is positioned between the pane and the cab frame, and when the latch is in an open position, the front window assembly is separated from the cab frame to permit egress from the interior chamber; and
a pressurization system for providing a positive pressure in the interior chamber relative to the surrounding environment, the pressurization system including a blower and a motor for driving the blower, the blower being in fluid communication with the interior chamber.

Abstract
An operator'"'"'s cab for a shuttle car including a cab frame, a window assembly, and a pressurization system. The cab frame defines an interior chamber and an opening. The window assembly includes a pane and a pane seal. The pane is coupled to the cab frame such that the pane covers the opening and encloses the interior chamber. The pane seal is positioned between the pane and the cab frame. The pressurization system provides a positive pressure in the interior chamber relative to the surrounding environment. The pressurization system includes a blower and a motor for driving the blower. The blower is in fluid communication with the interior chamber.
