Mining contractors can save nearly 50% of the time previously spent changing tires and this time savings translates into less downtime for tire maintenance and more operational time for each haul truck. The ACT wheel also enhances safety and reduces service technician fatigue. Service technicians no longer need to handle the outside wheel, which can weigh thousands of pounds. In addition, the ACT wheel reduces the use of heavy impact wrenches that were required in the past to torque and retorque 50 to 60 wheel nuts when removing a wheel and tire assembly.
