Test Overview Fuel Consumption and Production The WA500-7 was found to use less fuel in both V-Cycle and Load and Carry applications than the CAT 980K. However, due to CAT’s bucket shape and quick acceleration, the 980K was able to achieve higher production values than the WA500-7. Overall fuel efficiency was equal between the two machines. Regeneration • The WA500-7 uses mainly passive regeneration with no impact to performance. Active

regeneration happens automatically and does not interfere with machine operation. • The CAT 980K has a slightly different T4 interim solution than Komatsu. The C13

ACERT engine uses the “CAT Regeneration System” which uses a flame to achieve regeneration. The CAT system is automatic, like the Komatsu.

• Refer to Marketing News KMN2012003 “Face Off 2012 Tier 4 Engine Review” for additional regeneration information.

V-Cycle Loading

Test Details Machines were tested under similar conditions while V-Shape loading. The same material, set up and distances were used. Fuel consumption was measured and material was weighed during each test. Both machines were tested in both E and P-Modes. The CAT 980K consumes up to 8% more fuel than the WA500-7.

V-‐Shape ExplanationLoading

• The WA500-7 optimizes fuel consumption with Komatsu Smart Loader Logic (KSLL) giving it better fuel consumption than the 980K.

• The 980K has faster travel speed settings and quicker acceleration (overall and in each gear).

• The CAT bucket is designed to optimize productivity with less spillage. • The quick cycle time and optimized bucket means that the 980K has superior productivity

than the WA500-7. • Overall fuel efficiency is nearly the same on both machines.



Case Study – Fuel Savings The WA500-7 employs KSLL to automatically reduce fuel consumption when torque is not needed.

While operating in E-Mode, the WA500-7 consumes 13.9 gallons for the 980K’s 15.0 gallons. While this may not seem like a significant difference, over the course of a year, this can result in $8,800 difference in fuel cost. Likewise, a $4,800 savings can be found while operating in P-Mode. The WA500-7 in E-Mode can save over $13,000 a year when compared to the 980K operating in P-Mode.

Demo Tips and Takeaways Below is a quick guide for demo tips. For a complete guide, reference the Komatsu Marketing News KMN2013012 “New Dash 7 Midsize Wheel Loader Demo Tips.”

Setting Explanation BenefitPower = for maximum power such as needed for demos

Power mode provides top machine performance

Economy = for fuel savings or for light applications

Economy mode reduces fuel use in light duty applications

H = High engine RPM shift points => Hills

L = Low engine RPM shift poits => Level ground

Manual = manual shifting

On = automatically engage Torque converter.

Off = lock up engages as conditions allow

On = for load and carry applications

On will provide smooth ride in rough terrain

Off = for V-‐Shape Loading Off is best used during leveling

Electronically Controlled Suspension System (ECSS)

Conclusions

• CAT has increased the torque on the 980K compared to the 980H resulting in good acceleration.

• This combined with good work equipment speed and fast steering speed results in better productivity than the WA500-7.

• The 980K is offered only with joy-stick steering. o While smooth and efficient response at low speeds, it was found to be overly

sensitive at high speeds. • Overall fuel consumption of the WA500-7 is better than the 980K.

o However, fuel efficiency is about equal between the two machines. • The WA500-7 has superior creature comforts.

o The WA500-7 is more comfortable and quiet than the 980K while inside the cab.

o The 980K is extremely loud outside. o The WA500-7 has a better rear view camera and monitor with greater

resolution. • The 980K had a feeling of imbalance when moving heavy loads. This is due to a

greater load on the front axle from our weight study. • Komatsu offers both a steering wheel and joy stick steering (JSS) to allow for

flexibility in different applications.
