Case Studies

(Released in March, 2016)


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.

Powerful Engine

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.

Fuel Efficiency

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.

Enhanced Durability

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.

Simplified Maintenance

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.

Large Operator's Cabin

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.

Full Maintenance Contract

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. As a result, Sushee Infra is able to remain focused on excavation targets while Tata Hitachi's team of engineers ensures maximum machine availability.


ConSite is an automated data report service specifically designed for Hitachi construction machines with satellite system access. It leverages operational data relayed through the satellite to create an individual machine monthly report which is sent to the customer and the dealer along with alarm notifications. The alarm notifications are sent as they occur so that customers can identify operational issues with their machines in a timely manner.

More about the success of this project is mentioned in the next section of the case study. It showcases how Tata Hitachi has helped Sushee Infra make the most out of the razor thin margin it works on.
