Abstract: A mining shuttle car that trams on underground roadways includes a conveyor system and an operator's compartment adjacent to the conveyor system. The operator's compartment includes a rotatable seat and a control station. The operator's seat module is coupled to one or more joysticks that control the car, and the operator's seat module and the control station are mounted on a rotatable platform so as to be rotatable as a unit between a plurality of secured positions for operating the mining shuttle car. Forward movement of the joystick control relative to the seat steers the shuttle car about a point in front of the seat, and rearward movement of the joystick control relative to the seat steers the shuttle car about a point behind the seat. Forward and rearward movement of one of the joysticks steers the mining shuttle car in the same manner regardless of the rotational position of the rotational position of the seat.

Abstract: A sheave bracket directs a trailing cable of a mining vehicle. The bracket is hingedly secured to the vehicle and includes a plate and a plurality of sheaves coupled to and extending from the plate. The sheaves are arranged to guide the cable. The sheave bracket also includes a force control mechanism movable between two positions to adjust tension in the cable. The force control mechanism dampens strain in the cable when the direction of the bracket is changed.

Abstract: An electric vehicle powered by a trailing cable, the vehicle including a cable guide for guiding cable onto a reel as the cable is paid out and taken up. The cable guide comprises a pair of adjacent, double flanged concave rollers in alignment with each other so that their respective flanges are spaced apart by only a small distance substantially less than the cable diameter so that an essentially closed circular path is defined by the concave surfaces of the adjacent rollers so that the cable can not escape the rollers, each of the rollers including a polyurethane core that is hard and slick that creates a natural bearing surface, and an outer portion made of softer polyurethane than the core that aids in gripping and guiding the cable onto the cable reel.
