"As technologies advance, we use the c o r e t e c h n o l o g y t o r e f i n e p r o d u c t s t o give [mines] a huge advantage in opera- tional costs," he said, noting that among those advantages are fuel savings, a sim- pler design for reliability, maintainability and even the lessened need for costly, laborious maintenance equipment and man-hours. "It's more time to dig and produce, [thus] higher profitability." In terms of fuel efficiency, the OEM has reported cases where customers saw a 45% reduction in consumption versus a compa- rably sized mechanical drive wheel loader. Additionally, the SR Hybrid Drive sys- t e m i s a r e g e n e r a t i v e p r o c e s s .

For loader owners, the SR Hybrid Drive can also keep engine operation at a con- sistent RPM, saving money for its owner, a n d w i t h q u i c k e r c y c l e t i m e s a n d l e s s operator fatigue, an operator can also reap the benefits of time savings. With inherently less moving parts — electric drives have no power-robbing torque converter, no three-speed trans- mission, no transfer cases, no differen- tials and no power-transferring universal joints — there is less room for compo- nent failures, and often that aids in yet another benefit: longer lifespans.

Doing More With Less: the Joy Loader Line A review of Joy's loader choices reveals a wide range of payload lift capacities as well as vast capabilities for any coalfield. The largest is the L2350, with a standard payload of 160,000 pounds of lift capacity (LC); it is also produced in a high lift and super lift version. Featuring standard lift capacities are the L1850, with a 120,000-lb LC, the 90,000-lb LC model L1350, and the L1150, with 76,000-lb LC. Joy's smallest version, the L950, has a lift capacity of f r o n t - e n d l o a d e r s c o n t i n u e d February 2016 www.coalage.com 33
