Elevated time between overhauls, efficient discount of gas consumption and prices in addition to financial savings in carbon emissions; topped by unbeatable aftersales assist. Rolls-Royce says this was the results of a repowering of haul vans at certainly one of Yancoal’s open-cut coal mines in Australia’s Hunter Valley with state-of-the-art mtu engine options by Penske Australia. It provides that the outcomes have been so convincing that haul vans working at two extra Yancoal mines are actually being repowered by Penske Australia with mtu engines.
The undertaking started at certainly one of Yancoal’s mine websites within the Hunter Valley area of Australia, Mount Thorley Warkworth (MTW), which offered particular challenges for the haul vans used on web site. For each tonne of coal, round six tonnes of waste should be eliminated, and the gradients of as much as 10% imply that the vans should run at full rpm for a median of 1 third of the time so as to retrieve the coal.
The client beforehand had standard 2,500 bhp engines powering the haul vans that had come to the top of their life and wanted changing. The choice was made to repower the fleet of Komatsu 830Es with 2,500 bhp 16-cylinder mtu Sequence 4000 engines by way of distributor Penske Australia. Penske Australia backs the mtu know-how with an knowledgeable crew of engineers and factory-trained technicians designing, putting in, and commissioning repower options.
Rolls-Royce states: “The outcomes overwhelmingly satisfied the operators: the initially estimated 25,000 hours of engine life have been elevated to 36,000 hours. It is a profit that Yancoal is now extending throughout two extra mines, with a complete fleet of 75 vans being repowered throughout the Yancoal fleet.”
Shut cooperation between Penske Australia and Yancoal, and complete monitoring of the mtu engine revealed additional advantages: along with the longer time between overhauls, leading to decrease bills, the mtu engines at MTW mine additionally consumed round 6.8% much less gas than the earlier standard engine whereas sustaining the identical efficiency, accompanied by equal emission financial savings.
At two different mines, Yarrabee mine in Central Queensland and Moolarben in New South Wales, Yancoal operates fleets corresponding to the one at Mount Thorley Warkworth Mine. After a profitable tender course of, Yancoal and Penske Australia developed a plan to carry the reliability and efficiency of the mtu engine to the 19 Komatsu 830E vans at Yarrabee in addition to to the 17 Komatsu 830E and 5 Komatsu 930E vans at Moolarben.

By mid-2022, 46 Komatsu 830E/930E vans had been repowered and have been working with an mtu Sequence 4000 engine throughout the three Yancoal mines. The preliminary repower undertaking at MTW was launched in 2018 with a complete of 75 repowers anticipated to be delivered throughout the three mine websites by 2025.
The repowers of the 930Es was an vital milestone was additionally a part of the plan. As they accumulate service hours, they are going to be monitored in comparable element because the preliminary 830E truck repowers have been to precisely assess and validate the enterprise case value advantages for Yancoal partnering with Penske Australia and powering their mining vans with an mtu 16V 4000 C01 engine.
Rools-Royce concludes: “Engineered and constructed particularly for mining, the mtu Sequence 4000 is broadly considered the business’s ultimate engine for high-horsepower purposes, on account of its superior sturdiness, gas economic system and low complete value of possession. In an effort to meet this customary, even after the primary lifetime of an engine, we offer absolutely customised repowering options for each doable requirement and any utility. We obtain this by way of over 25 years of expertise with the engine sequence, which is by now in its fifth and most superior technology.”
It provides that the effectivity of its repowering course of ends in typical gear outage of 1 week or much less, with many gear operators having saved sufficient in gas, upkeep and restore prices to return their repower funding earlier than the primary overhaul.
