UNDERGROUND LOAD & HAUL RCT is providing innovative LHD automation solutions at Independence Group (IGO)’s Jaguar operation Tramming versatility From new battery electric offerings to versatile automation packages, there is all to play for in the underground load and haul market, reports Paul Moore hile often the launch of the largest equipment gets the most interest, in reality the market for the more compact equipment is much bigger in terms of overall numbers of machines. Caterpillar recently introduced the new Cat ® AD22 articulated truck, a new size that joins its proven lineup of rugged machines designed for underground hard rock mining. “While this newest addition to our underground truck product line is the smallest truck we offer, it’s designed to deliver the performance and durability of its larger counterparts — and a greater payload than our competitors’ trucks in the same size class.” Developed in response to the trend of mines going deeper underground to access narrower, more targeted ore bodies, the AD22 is described as a robust, dependable truck capable of manoeuvering in smaller mines. The AD22 offers a 22 t payload in a compact package. “Its small operating envelope and agile characteristics, including an acute articulation angle and W decreased outside turning radius, enhance productivity in these specific applications. And its wide body design makes loading faster and easier.” The AD22 takes advantage of Caterpillar ergonomic designs to create controls and instrumentation that help operators perform efficiently. An easy-to-read full colour LCD screen displays machine status. The truck is available with an open operator compartment or an optional enclosed cab. The enclosed cab was specifically designed to help deep-mine operators keep their employees cool and breathing filtered, conditioned air. On the other end of the temperature spectrum, the AD22 can be equipped to handle Arctic conditions. Both cab options are ROPS/FOPS certified. An oscillating hitch helps absorb haul road irregularities.
