MINING TRUCKS about 10 % improved trolley performance.
In addition, the then LANDCROS will offer a retrofit kit for diesel electric AC-5 trucks. What about a launch customer for the commercial truck? Kitic:“ There has been huge interest and momentum over the last six months- we want to make sure we choose the right customer but also make sure we are able to manage and supply the demand that’ s coming through at the moment. We’ ve had a lot of discussions about potential fleet replacement as well as customers wanting a retrofit kit. Crucially we’ re not talking about what may happen, we have already validated the technology- we’ ve got confidence in the life of this battery and commercially, the truck is viable and practical with today’ s technology.”
It makes sense that the commercial battery electric truck will be based on the AC-5 truck given a series of improvements that it incorporates – currently the EH4000AC-5 has been launched already( 242 t payload – 21 t higher than the EH4000AC-3) with the EH3500AC-5 and EH5000AC-5 to come.
Looking at the diesel electric differences and benefits, the AC-5 delivers stronger uphill performance than the AC-3. A highcapacity grid box and refined brake system support stable retarding during loaded downhill runs, maintaining consistent deceleration across long hauls. Compared
with the AC-3, it improves speed both uphill and downhill, reducing total cycle time. Even in tough terrain, the AC-5 ensures reliable speed and control- boosting haul productivity. The brake performance was enhanced by changing the hydraulic brakes from front dry brakes to wet brakes and enhancing the performance of the retarder auxiliary brakes. As a result, they demonstrate stable braking force even in harsh mining environments.
The AC-5’ s high-rigidity frame is engineered through advanced stress analysis to maintain stability under heavy payloads. Enhanced structural durability and optimised control systems ensure safe, efficient hauling. Compared with the AC-3, the AC-5 supports higher payloads without sacrificing speed or control- delivering maximum productivity across the haul cycle.
The AC-5 also enhances fuel efficiency without changing the engine. An adaptive twin-fan cooling system delivers just the right amount of cooling when needed- reducing unnecessary energy use. Selectable work modes help tailor performance to site conditions, optimising fuel consumption. This balance of power and efficiency maximises haulage per litre of fuel. The AC-5 trucks are also equipped with a new feature that allows operators to select from three different driving modes( High Power Mode, Power Mode, and Eco Mode) according

to the site environment. Operators can select Eco Mode when they wish to reduce fuel consumption or High Power Mode to maximise driving performance for efficient operation..
