Titan Wheel Corp.’s new Accelerated Change Technology (ACT) wheel is designed to allow service technicians to change or rotate the rear tires on a haul truck in less time. The company says the system enhances safety, reduces service technician fatigue, and increases profitability by reducing tire maintenance downtime. The wheel features a two-piece lock ring that releases the tire assembly from the wheel, allowing the inner dual wheel to simply slip over the outer wheel. The ACT wheel is said to save nearly 50 percent of the time previously spent changing tires.
