India is at the center stage of growth and development. As one of the world's fastest growing economies, India's energy needs have risen steeply. Coal is the most important indigenous energy resource. It remains the dominant fuel for power generation and finds use in many industrial applications including steel and cement. Even though India is one of the top producers of coal in the world, it still imports coal to meet growing domestic consumption. India has a strong focus on reducing its reliance on energy imports and is making significant investments to boost energy infrastructure.
The excavation and processing of coal is executed by mining companies hired by Coal India Limited (CIL), the state owned coal mining corporate, and its subsidiaries. Sushee Infra & Mining Limited is one of the key organizations engaged in over burden removal across mining sites in India. Through consistent performance improvement, Sushee Infra has earned for itself the reputation of bagging repeat government orders.
However, with growth have come a few challenges. Sushee Infra is under immense pressure to enhance the pace of over burden removal and simultaneously bring down the costs. Sushee Infra joined hands with its long standing partner Tata Hitachi by providing state-of-the-art construction equipment for over burden removal at the coal mines of Sathupalli. Tata Hitachi is a prominent player in the construction equipment industry in India. Tata Hitachi's vision of empowering people and the communities reverberates with Sushee Infra's vision of nation building and making India self-reliant.
In order to ensure lower cost of production and faster execution, Tata Hitachi has provided Sushee Infra its latest range of hydraulic excavators, the ZAXIS 470HGI series. In a short span of time, the GI series has become a preferred choice of miners across continents. These hydraulic excavators are powerful, deliver high production with impressive fuel economy, offer swift front movements, are easy to operate and durable as well. All these factors contribute to the low running costs of ZAXIS GI series hydraulic excavators.
Some of the key features of the ZAXIS 470H GI series hydraulic excavators deployed at the Sathupalli coal mines are:
ZAXIS 470H GI series hydraulic excavators are delivering exceptional results under varying soil conditions at the coal mines of Sathupalli.
This case study will further divulge details about the major challenges encountered by Sushee Infra at the coal mines of Sathupalli and how the company harnessed immense capabilities of ZAXIS 470H to meet stiff cost and project timelines and simultaneously retained profitability.
With the growth in the coal industry, competition in the form of new mining companies has started pouring in from all directions. This is accompanied by ever mounting pressure to increase production, while significantly bringing down the cost incurred. All these factors have led to a situation where a mining company is pressed hard to find new technologies and excavation techniques which are not just cost-effective but also strengthen the bottom line.
Sushee Infra & Mining Limited, better known as Sushee Infra, one of the leaders in the mining industry, also encountered similar challenges at the coal mines of Sathupalli. Sushee Infra leveraged its industry expertise to evaluate the key factors which, if addressed, would help achieve the targets while still remaining profitable.
Every coal mining project relies heavily on construction machinery for over burden removal, especially the hydraulic excavators provided by the Original Equipment Manufacturer (OEM). At the coal mines, the hydraulic excavators work in a 24X7 environment under gruelling conditions. These machines can prove to be the determining factor for the success of a project.
Sushee Infra was evaluating different options in the hydraulic excavator's market and assessed all the options against the following parameters:
With challenges laid out, it was time for Tata Hitachi to come up with a well-crafted solution that would precisely meet the requirements.
Tata Hitachi is at the forefront of construction equipment industry in India. Over the years, Tata Hitachi has expanded and created a robust, diversified product portfolio which boasts of state-of-the-art technology, unmatched quality and strong adherence to compliances.
Sushee Infra, a highly-valued customer of Tata Hitachi, required hydraulic excavators which would be highly efficient, perform in varying soil conditions, require least maintenance and showcase unmatched durability. Tata Hitachi's latest in the line of hydraulic excavators - the ZAXIS 470H GI series - matched all these requirements. A fleet of ZAXIS 470H hydraulic excavators was therefore deployed at the coal mines of Sathupalli for over burden removal.
Here is how the GI series has helped Sushee Infra overcome the cost and time challenges and still remain profitable.
ZAXIS 470H GI series hydraulic excavators are powered by a 315 HP engine. This powerful engine makes the machine capable of achieving higher production in tight job schedules. Moreover, this engine has a proven track record of showing impressive durability at countless mining sites around the world.
HIOS-III (Human Intelligence Operating System) is the latest hydraulic technology offering from Hitachi across the globe. The improved hydraulic control system not just ensures swifter front operations, but when coupled with the fuel-thrifty diesel engine, it helps deliver significant fuel savings as well.
Fuel economy is further enhanced by the two operating modes viz., PWR (Power) and Eco modes provided in the ZAXIS 470H. PWR and ECO modes ensure high production at low fuel consumption. When operated in ECO mode, the excavator reduces the fuel consumption further without compromising the digging force of the excavator.
ZAXIS 470H features a heavy duty undercarriage for demanding Indian conditions, a larger pin diameter and reinforcements on front attachments - arm and boom. All these features result in enhanced durability and make ZAXIS 470H one of the most durable hydraulic excavators in its class.
GI series hydraulic excavators are a fine example of meticulous engineering. The inspection points are concentrated on the wall around the engine. A walkway has been provided in center of the upper structure for easy access to the engine and inspection points. This ensures easy maintenance of the engine oil filter, pilot filter, drain filter and water separator. Moreover, the service intervals are long enough to keep the maintenance costs low.
The operator's cabin on ZAXIS GI Series has been designed with special focus on operator's comfort, safety and ergonomics. The FOPS (Falling Objects Protection System) cabin is robust and complies to ISO 3449 Level-I and Level-II.
Tata Hitachi has provided a Full Maintenance Contract (FMC) to Sushee Infra. It goes beyond 25000 Hrs of machine operation. The FMC ensures high availability of machines which is very important to attain the production timelines. As part of FMC, Tata Hitachi maintains a dedicated spare parts warehouse on site and also provides experts including engineers and technicians to take good care in case a machine breaks down.
