AutoMine ® Lite provides extra productive hours each day by allowing the continued operation of the loader or truck during blast clearance times. Additionally, equipment utilization is increased as operators can hand over between shifts much faster without the need to locate and travel to the equipment. Another advantage of AutoMine ® Lite is that it significantly extends the lifetime of equipment, available later this year.

Caterpillar recently announced the availability of a highly efficient diesel exhaust particulate filter( DPF), a Wall Flow Filter, for its larger LHDs and largest truck. The Wall Flow Filter removes more than 98 % of particulates in the exhaust stream, as compared to the Flow Through Filter, which removes more than 50 %.
The new filter adds another level of

emissions control to the Cat Ventilation Reduction Package, which employs specialised hardware and software to govern the combustion process and reduce emissions and fuel consumption. The Flow Through Filter and Wall Flow Filter offer aftertreatment options and create a system that is scalable to meet the needs of the mining operation. All of the options can be retrofit. Both aftertreatment filter packages require the use of ultra low sulphur diesel fuel and low ash engine oil, but none of the options require the use of diesel exhaust fluid( DEF). Caterpillar suggests contacting the regional Cat dealer for specific recommendations.
The new R1700 also delivers significant technology enhancements. It is equipped with multiple subsystems for fast technology implementation. The Cat MineStar Command system enables operators to work from a remote location and enables the LHD to drive and dump autonomously. Remote machine health monitoring, payload monitoring and other technology options are also available.
For the entire LHD line, Caterpillar is now offering Bolt On Half Arrow GET for bucket edges. The system is designed for high abrasion applications where weld on GET experience high wear rates. With a proven and reliable retention system, the bolt on GET offer more wear material than standard weld on GET, and the bolt on design enables fast and easy removal and replacement. Longer life and faster replacement means less downtime.
The Cat Bolt On Half Arrow GET enhance productivity in additional ways. The segments are designed to minimise carrying weight while keeping the bucket protected, and despite additional wear material, the low profile front edge eases pile penetration and promotes fast bucket loading.
