A braking system for a lift truck (100, 100A) performs all service braking using truck traction drive motors (202, 204). Mechanical, spring applied, electrically released brakes (218, 220) are coupled to wheels (210, 212) on opposite sides of the truck with the mechanical brakes applying unequal braking forces to the wheels. The mechanical brakes perform park braking and, in the event an electrical system problem arises, backup braking as well that can be modulated by an operator of the truck regardless of the operating condition of the truck. |
