A drive assembly for a mining vehicle includes a frame, a housing coupled to the frame, and a motor positioned in the housing. The motor includes a motor frame with a first axial end and a second axial end opposite the first axial end. The drive assembly also includes a transmission that is positioned at least partially within the frame. The transmission is coupled to the motor frame at the first axial end. The drive assembly further includes a support assembly that couples the second axial end of the motor frame to the housing.

Crawler drive system

A drill rig includes a base, a drill tower coupled to and extending from the base, a drill pipe coupled to and supported by the drill tower, an air compressor coupled to the base, a prime mover coupled to the air compressor, and a fluid coupling disposed between and coupled to both the prime mover and the air compressor.

Fluid coupling drive system for a drill rig air compressor

A mobile mining machine includes a base with a deck and a counterweight box, a hoist drum supported on the deck, a motor drivably coupled to the hoist drum, a main transformer configured to supply power to the motor, an auxiliary transformer, and an electrical room coupled to the base. The main transformer and the auxiliary transformer are positioned inside the electrical room, and the electrical room contains at least one unguarded electrical connection.

Medium voltage room for a mining shovel

A leveling system for supporting a drill assembly includes at least one hydraulic actuator and a manifold coupled to the actuator. The hydraulic actuator supports the cab relative to a support surface, and includes a first end coupled to the cab and a second end that is extendable away from the first end. The manifold is coupled to the actuator and includes a directional flow control valve, a regenerative flow valve, and at least one counterbalance valve for controlling the extension of the actuator. The counterbalance valve is in direct fluid communication with the actuator.

Leveling system

A seat module for an industrial machine. The industrial machine includes a base, a body, and a cab module supporting the seat module. The seat module includes a seat, a control panel mounted on the seat, one or more monitors attached to the control panel, and a plurality of controls positioned on the control panel. The seat module also includes a controller having a processor and connected to the control panel. The controller is configured to receive information from the plurality of controls and to control the operation of the industrial machine based on the received information.
