We want to help our customers achieve their sustainability goals by offering products that are designed with a range of environmental features that can reduce CO2 emissions, while maintaining productivity. One such feature is:
What is EH Tuning Package?
EH Tuning Package (EHTP) is a software-based program designed to optimize Hitachi Construction Machinery trucks to suit their work conditions in order to consume less fuel and subsequently, reduce the customer's fuel costs too. We know that not all mine sites are the same, with diverse environmental conditions such as surfaces, gradients and climate combining to influence the performance of each machine. By reducing fuel costs through EHTP, we can help customers maintain a low life cycle cost (LCC), with almost no impact on productivity.
What are the benefits?
By monitoring on site activity of each Hitachi Construction Machinery dump truck with the EHTP, we can customize how each customer’s truck functions in order to help manage their fleet in any mining operation, leading to fuel savings and a lower cost per tonne (which contributes to lower LCCs).The fleet’s AC Drive System can be tuned in order to work more efficiently with the actual gradients, surfaces, length of haul road and other conditions on site, reducing fuel consumption by up to 10%*,without sacrificing driving performance. EHTP can also provide the customer with other benefits including reduced carbon emissions and reduced ambient and cab noise by up to 2dB.
How does it work?
We can identify the right performance levels for the customer’s fleet through comprehensive monitoring of selected components.
- Testing of EHTP is conducted on the mine site on one fleet truck
- Downtime is minimal with each testing cycle only 10 minutes in duration
- Testing results are then analyzed and presented to the customer and together, Hitachi Construction Machinery and the customer can determine the best tuning pattern for their operation
- The AC Drive System is then tuned to optimize engine output, speed and travel torque to benefit the customer.
In just one day, Hitachi Construction Machinery can install the optimized EHTP software on an entire truck fleet and the fuel savings can begin. EHTP is available on the following models (original Cummins or MTU engine must be installed):
- EH3500AC-3
- EH4000AC-3
- EH5000AC-3
- EH3500ACII
- EH4000ACII
