mining . GHH is able to support customers in various low profile mining operations with machines for both production and development ends covering stope heights from 1.7 to 2.4 m high . The hard rock offering has variants of aircooled and water-cooled engine packages to suit various global customer needs , with strong commonality and modularity across the low profile LHD fleet to be able to support customers with reduced parts holding due to common parts across products .
In a drive to constantly improve and develop its products GHH says it has also worked on enhancing its already well proven , true 8 t low profile LHD , the SLP-8 . The LHD has recently gone through improvements to enhance performance and assist customers in achieving higher productivity and reduced operating costs like the implementation of a swing cooler for ease of maintenance and reduced downtime and off the shelf harness availability to also reduce downtime . “ With the best in class payload , the SLP-8 is tailor made to be robust , reliable and durable with long frame lifetime of over 20,000 engine hours without issue . The CE Certified SLP- 8 has a Deutz TCD 2013 Stage 3 engine 179 kW with optional DPF available to reduce DPM and CO2 .”
The ROPs / FOPs operator compartment is ergonomically designed with optimised visibility , including a camera system for improved visibility

if needed and an easy to use 7 in touch screen . The new brake pedal design and aircon blower are just a few of the extras focused on operator safety and comfort . The SLP-8 has best in class ground clearance for harsh underground mining conditions , with a cooling system designed for greater than 53 ° C ambient and 20.5x25 tyres to negotiate inclined up dip loading , with improved traction and longer tyre life for improved performance and reduced operating costs . From a safety perspective the machine comes with accumulator discharge so there is no stored hydraulic pressure on the machine .
The SLP-8 comes with Wi-Fi connectivity , including full machine condition monitoring , bucket weighing for productivity monitoring with bucket tips , electric brake wear sensors and a proven certified controller for underground mining .
Looking at the road to automation , GHH , and its partners Nerospec SK and K + S , have recently concluded on site implementation of a fully autonomous single loader , the SLP-14H , in a room and pillar operation , where the LHD not only avoids recognised obstacles without any further consultation of humans , but it also executes a fully autonomous complex loading
The new R2900 XE offers an impressive reduction in tyre wear , which Caterpillar attributes to the new traction control system design
strategy , which has not been heard of before .
It adds : “ Other than in narrow vein applications , where positioning of the loader is straight forward , the attack strategy in broader room and pillar applications is critical to achieve a complete and efficient loading cycle , which the developed system does . After successful mucking , the loader will navigate to the dumping location and approach it without use of any optical technology , which is susceptible to dust . Once dumping is completed the machine will continue the work cycle and return to the mucking location or switch to the next location , depending on what work sequence has been given by the leaving shift team .”
The GHH loader and truck range is all available with a PDS Level 9 interface as well as automation-ready and available with GHH inSiTE , its digital analytics solution , which can be customised to support specific customer and application needs .
Evolution of the Cat R2900 XE
Caterpillar gave MINExpo 2021 attendees a taste of what was to come for the future of underground load-haul-dump ( LHD ) loaders with the new diesel electric Cat ® R2900 XE underground LHD loader . Offering insight into the machine ’ s high-efficiency Switch Reluctance ( SR ) electric drive system and redesigned axles , the display featured the new LHD ’ s drivetrain as part of Caterpillar ’ s underground exhibit .
The Cat R2900 XE LHD is now commercially available to underground mining operations globally . It features optimised lift arm geometry and componentry plus load-sensing hydraulics to improve breakout force by 35 % over the R2900G . Accelerating from 0-24 km / h ( 0-14.9 mph ) in 6.4
