MINING Now Available in India EQUIPMENT High-End SolutionsBhavani Balakrishna ccording to a study by Mckinsey and CII, the Earth Moving and Construction Equipment industry in India is poised for exponential growth with a potential to grow to US$12-13 billion by 2015. The key sub-segment within earthmoving equipment is excavators which accounts for over half the market followed by backhoes with 26 per cent and loaders with 5 per cent. This calls for a significant need for bigger capacity earth-moving machines with higher productivity machines having longer uptimes. Below are few brands of high-end mining equipment available in India across different categories of mining equipment.

The engine's high torque at low rpm gives the L120F outstanding rimpull and low fuel consumption. Volvos patented lift arm system TP-linkage combines high breakout torque with very good parallel movement. JCB's 456ZX wheel loader boasts an air-to-air intercooled low-emission engine with electronically controlled fuelinjection system. This delivers high torque at a low engine RPM, enabling the operator to fill the bucket faster. The 456 is fitted with standard torque proportioning axles that keep the machine moving even in difficult conditions. Heavy duty three ram geometry provides high breakout forces with excellent loading characteristics. The pin, bush and sealing design on all pivot points provide extended maintenance intervals. Caterpillar provides a complete range of wheel loaders suitable for mining. These include the following. Volvo's wheel loader, L120F's technical specifications are given below. L120F Engine ...

ISO 9249, SAE J1349 net, kW (hp) Tires Breakout force, kN Static tipping load at full turn, kg Bucket capacity, m3 Log grapples, m2 Specifications Volvo D7E LA E3 28,3 (1700) 180 (245) 179 (243) 23.5 R25, 750/65 R25 164,0* 12 140* 2,6-9,5 1,1-2,4 Operating weight, t 19,0-21,0 * Bucket: 3,4 m3 straight with bolt-on edges, Tires: 23.5 R25 L2, standard boom. Due to the bucket design and the TP-linkage, the bucket fill factor for Volvo's L120F is often more than 100% when compared to the SAE volume. The system utilizes variable displacement piston pumps to circulate oil only when and where needed. This saves fuel and conserves engine power for greater penetration when loading the bucket and going uphill. It also gives faster cycle times in load and carry operations.
