Caterpillar announces new mining motor grader

surfaces in any direction without the need for complicated configurations. Whatever the orientation of the scanner, integrated levelling automatically corrects scans before processing. New functionality on the tablet con- troller allows users to import mine CAD strings and surfaces to view together with scans. This facilitates real time comparison between the scans and allows users to compare this directly to the mine plan or geological models while underground. “Operations which choose Maptek laser scanners for one particular survey applica- tion quickly find many more uses across their different engineering and plan- ning disciplines,” said Mine Measurement Product Manager for Maptek, James Howarth. “Customers have called the tech- nology a game changer for improving site efficiency and enhancing integration of sur- vey with mine planning.” Maptek, tel (+27 11) 750-9660, e-mail: info@maptek.co.za than on the 24M. Maintenance intervals for the transmission, hydraulic filter and engine air filter, as well as service life for the transmission and rear axle fluids have been doubled, which significantly reduces service time and costs. The Cat 24 features 15 strategically located tie-off points to protect service technicians when performing certain ser- vice operations. The machine is Fire Suppression Ready, which allows for easy mounting and accommodation of most fire suppression systems. Additionally, a fire suppression system is available from the factory as an option. The automatic power shift transmis- sion uses the Cat Advanced Electronic Control Strategy (APECS) for smooth shifting, extended component life and improved operator comfort. Two electro- hydraulic joysticks reduce hand and wrist movements by up to 78 per cent over con- ventional lever controls, further improving operator comfort and productivity. The Cat 24 is MineStar™ ready and the machine comes standard with Cat VIMS™ and Product Link™ Elite, which delivers advanced machine operation reporting through VisionLink®.

XR3 and long range LR3, which came onto the market in 2017. The R3 series is 30 % smaller and 25 % lighter, with 2,5 times faster data acquisition than the earlier I-Site 8000 scanners. Survey teams can work faster and smarter, with confidence that accurate, current topographic and vol- umetric data is guiding mine planning and geotechnical investigations, says Maptek. The SR3 laser scanner weighs only 9,6 kg and is accurate to 4 mm. Surveyors will be able to measure stopes, drives and tunnels with ease. High resolution laser scans collect detailed data for geological and geotech- nical face mapping. High fidelity imagery captured underground at the same time as scanning provides context and support for analysis and communication. A scan window of -40 deg to 90 deg ver- tically and 360 deg horizontally captures all decreases rolling resistance and reduces premature tyre failure. The new motor grader features opti- mised weight balance and 15 per cent more low-end torque compared to the Cat 24M. These features improve trac- tion and help maintain consistent ground speed, especially when carrying a large load on the moldboard, working on grade or turning under load. An 11 per cent increase in machine weight provides additional blade down pressure and tractive force to increase blading performance, and Consistent Power-to-the-Ground controls engine power levels to offset cooling fan losses, allowing the motor grader to deliver opti- mum performance at all times. The Cat C27 engine with ACERT™ tech- nology delivers reliable performance and prolongs target rebuild life by 33 per cent over the C18 engine. The new 533-mm, six-speed planetary transmission and improved rear axle bevel gear and final drive extend lower power train service life by up to 33 per cent, substantially lowering service costs. The Cat 24 features a modular design that reduces downtime associated with the removal and installation of main compo- nents. For example, the transmission can now be removed up to 70 per cent faster

Building on the strong heritage of the M Series Motor Graders, the new Cat® 24 Motor Grader is said to deliver high per- formance construction and maintenance of mine roads to improve mining truck efficiency. The 24 Motor Grader is equipped with a 7,3-m wide moldboard and is applica- tion matched for medium to large mines running trucks with payloads of over 180 tonnes. An innovative, modular design means components can be removed and installed quicker and easier – in some cases, up to 70 per cent faster when com- pared to the 24M. Standard Cat GRADE with Cross Slope improves operator productivity and haul road quality, which lowers truck tyre wear, The new Cat® 24 Motor Grader is said to deliver high per- formance construction and maintenance of mine roads to improve mining truck efficiency.

New SR3 underground laser scanner fromMaptek Maptek has introduced the Maptek I-Site SR3 600-metre range laser scanner, which it believes is destined to become the mine measurement standard for underground operations. The SR3 follows the extra-long range
