AccessDirect AccessDirect is an electrical interface system that facilitates remote access to a machine’s onboard com- puter via the Internet. With AccessDirect, maintenance personnel can analyze faults from off-site locations and arrive on-site prepared to resolve issues, leading to reduced machine downtime. AccessDirect also enables factory experts to remotely access and troubleshoot faults, resulting in superior response times and reduced mean time to repair. AccuLoad AccuLoad is a data analysis system that provides real- time feedback on dipper loads. AccuLoad’s payload calculation is accomplished without mechanical sensors, eliminating the need for recalibration, which is a com- mon problem with other load weighing systems. The system can be employed to calculate material moved, to monitor overloading of trucks, or to allow operators to study their loading efficiency and shift performance. It can also log operator performance data which, when paired with MIDAS, can generate reports to help iden- tify training opportunities to increase shift production. MIDAS The MIDAS health monitoring system continues to optimize machine performance by providing, logging and analyzing data on a variety of machine variables. MIDAS comes complete with a built-in report generator that outputs data in a format that can be easily analyzed to identify opportunities to improve machine perfor- mance. When paired with AccessDirect and AccuLoad, MIDAS provides real-time monitoring of shovel opera- tion and provides users with a 3D model to watch the shovel in motion.

LatchFree™ The LatchFree Dipper System is Caterpillar’s solu- tion to customers’ number one cause of downtime — the traditional latch assembly. The LatchFree dipper eliminates the latch assembly, replacing it with a strong steel link mounted to the dipper back, away from mate- rial flow. The system enhances safety by reducing the number of maintenance events required to maintain the system and increases reliability by reducing unplanned downtime. The LatchFree Dipper System comes com- plete with a comprehensive training program to ensure customers achieve maximum system benefits, and is currently under a controlled release. FastFil™ Dipper Design The unique FastFil dipper provides customers with faster and fuller dipper loads where the application per- mits. Its trapezoidal shape accommodates the natural configuration of the load, eliminating voids that occur with box-shaped dippers for improved fill factors. The trapezoidal shape also optimizes dipper size and weight for improved maneuverability and faster swing times. Additionally, an adjustable pitch brace allows rake angle changes to improve bank penetration, eliminate bulldozing, and improve productivity. Combined, the FastFil features maximize the fill factor. Operator Assist — Enhanced Motion Control The operator assist — enhanced motion control sys- tem eliminates or reduces the occurrence of crowd over-speeds, crowd impacts, hoist stalls, boom jack- ing, and swinging while engaged in the bank. This is accomplished by intelligently controlling how motions are allowed to operate under certain conditions. The reduced system stress and equal or better cycle times improve shovel performance and cost per ton. This soft- ware is standard on all 7495 Series electric rope shovels.
