APEX

Longer life, less weight, all performance. Confidence in every descent.

APEX is the smarter upgrade for mining fleets that demand consistent braking under extreme duty cycles. Purpose-built with a radial grid resistor system, APEX delivers cooler operating temperatures, sustained braking availability, and superior durability. The result: lighter weight, quieter operation, easier maintenance, and less strain on the deck all while reducing life-cycle costs.

Why APEX? By keeping grid resistors cooler and more stable than OEM designs, APEX ensures braking systems stay in their optimal range to deliver the confidence of consistent, sustained performance on every haul.
