NARROW VEIN OCTOBER 2017 • E&MJ; 59 www.e-mj.com can reach 24 ft. "We sold 3224s for many years to Canadian potash mines with tight conditions," Hardman said. "We have made some improvements to this machine as well. It's a little more robust. We recon- figured the design and placed the cab in the center on the top for better visibility. The original model was a slower tramming machine. We added a power-shift trans- mission to increase the tramming speeds from 5 mph to 10 mph." Some of the mines in Mexico need a scaler with the additional height and Fletcher will show- case this at a Mexican mining conference in Guadalajara during October. Sandvik Targets the Loading Process Sandvik recently introduced a new 3-met- ric-ton (mt) capacity narrow-vein loader (LHD) that offers improved reliability and productivity and increased safety for its size class. The Sandvik LH202 loader is targeted for narrow-vein mining applications with tun- nel widths between 2 meters (m) and 2.5 m. It has been designed to help reduce dilution and improve flexibility and operator safety when working in narrow-vein operations. The LH202 is full of features to help mines maximize tons and minimize ex- traction costs. It has been engineered to optimize machine width, length and turn- ing radius. Sandvik believes the LH202 can reduce cost per ton by up to 36% thanks to its reduced operating width and larger capacity compared to other loaders in the same size class. "Due to its compact size and advanced transmission, Sandvik LH202 is both easy to drive and maneuver in confined spaces typical of narrow-vein tunnels," said Kimmo Ulvelin, product line manag- er, narrow-vein and low-profile loaders for Sandvik Mining and Rock Technology. Ashleigh Braddock, global sales and marketing support manager, product area load and haul for Sandvik Mining and Rock Technology, said an operator com- partment located in the loader's rear frame helps improve operator safety and comfort. "With this safety design, we have moved the operator further away from falling rocks during bucket loading," Braddock said. "Improved visibility and powerful LED lights help reduce colli- sion risk while ground-level daily main- tenance reduces risk of slips, trips and falls. Enhanced ergonomics in the opera- tor compartment keeps the operator more comfortable during the shift, enabling to focus on production." With sustainable operation in mind, and to enable the use of Sandvik LH202 in markets with low engine emission require- ments, the new loader will be available with either a standard Tier 2 engine or a lower-emission Tier 4 engine in the future. The new Sandvik LH202 completes a comprehensive offering of Sandvik load- ers engineered for narrow-vein opera- tions. From Sandvik LH201, our small- est loader with a payload of 1 mt and capable of operating in tunnels as narrow as 1.5 m, up to the Sandvik LH307, with a tramming capacity of 6.7 mt in tunnels that are greater than 3 m wide, we offer a narrow-vein loader with an optimized capacity and envelope for your unique operation.
