Low friction sheave bracket

A sheave bracket for directing a trailing cable of a mining vehicle, the vehicle including a cable management system, the bracket comprising:

• a lower plate;
• an upper plate spaced from and extending generally parallel to the lower plate;
• and
• a horizontal roller coupled to and extending generally parallel to the lower plate, the horizontal roller being positioned between the upper and lower plates and being arranged to elevate the cable above the lower plate;
• wherein the lower plate defines an aperture configured to allow material flow therethrough.

An electrically powered mining vehicle comprising:

• a frame supported for movement over the surface;
• an electric motor coupled to the frame for providing power to the vehicle;
• a cable electrically coupled to the motor for supplying power to the motor;
• a cable management system coupled to the frame and arranged to receive and payout the cable as the vehicle moves over the surface;
• and
• a sheave bracket coupled to the frame and arranged to direct the cable into the cable management system, the bracket including
• a lower plate arranged generally horizontal,
• an upper plate spaced from and arranged generally parallel to the lower plate, the upper and lower plates defining an inlet and an outlet, the outlet being located closer to the cable management system than the inlet,
• a plurality of vertical rollers coupled to and extending between the lower plate and the upper plate, the vertical rollers being arranged to guide the cable into the cable management system,
• a first horizontal roller coupled to the lower plate proximate the inlet and arranged to elevate the cable above the lower plate, and
• a second horizontal roller coupled to the lower plate proximate the outlet.
