SLOWDOWN; AVOID AREA Notify appropriate personnel of a severe hot spot on the haul road. Avoid this spot on the next cycle or reduce truck speed by approximately 15 km/h (10 mph) near this area. The major components of the machine may feel excessive stress at this location. Avoid these locations, when possible.The RAC warnings should be made into a Key Performance Indicator (KPI) for the truck operators and the mine's haul road maintenance crew. The Key Performance Indicators allow the customer to establish a baseline in lowering the overall operating cost of the machine. Because the RAC events are displayed via the VIMS message center, the operator is now informed when the truck is exposed to excessive forces. The RAC module alerts operators to take corrective action until the haul road can be repaired. Operators benefit from less fatigue by avoiding bad spots in the haul road.
