Bell ADTs benefitting from EU Stage V MTU Engines from Rolls-Royce

Bell Equipment, the articulated dump truck (ADT) specialist, recently received the first six Series 1000 – 1500 MTU engines from Rolls-Royce that meet the new EU Stage V emission standard, the engine specialist said.

The engines cover a power range from 170-430 kW.

The order had been preceded by a test phase of several years under the most adverse operating conditions in order to ensure the trucks would be guaranteed a reliable, cost-effective upgrade, according to Rolls-Royce. To this end, MTU’s off-road engine series were optimised to comply with the emission standard and a new exhaust aftertreatment system introduced.

In preparation for the more stringent emission requirements, Rolls-Royce had made two Stage V prototypes available to Bell for field trials in 2016 – a 260 kW MTU 6R 1000 engine and a 430 kW 6R 1500 were successfully tested in the hot, dusty climate of South Africa and for the tough conditions encountered at extreme altitudes of up to 3,000 m.

Bell and Rolls-Royce with the MTU brand have been working together closely since the 1990s, with Rolls-Royce not only the supplier of more than 1,000 MTU engines a year, but also the technology partner in all emission-related design and construction decisions – including the upgrading of the ADTs.

Stefan Rudert, Head of Sales and Application Engineering for Construction & Agriculture at MTU, said: “During the field trials, we accumulated an enormous amount of experience that goes way beyond any simulation on a test bench, since the real-life interplay between the engine and the vehicle affects the behaviour. Data obtained during the field tests, which we collected from sensors mounted on the engines was subsequently used in the configuration of the components.”

The new Stage V engines, which Bell will successively upgrade to, besides MTU’s current SCR exhaust technology, also include a diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF), with all components installed in a compact one-box solution behind the driver’s cab, according to the company.

“Another positive aspect of the new emissions technology is that it reduces fuel consumption,” the company said. “To prepare for the upgrade to the new emission regulation, Rolls-Royce had around 100 MTU engines undergoing trials with various vehicle manufacturers.

“In total, over 110,000 operating hours were accumulated as a result, with individual engines running non-stop for more than 4,000 hours. Since the trials had started at an early stage, the MTU engines were certified in accordance with the EU Stage V regulations by mid-2018, marketable and ready for series production.”

Doosan ups the distribution ante in North America

Doosan’s Infracore North America division has opened a new 100,000 ft² (9,290 m²) parts distribution centre serving its dealers and Doosan customers in the US and Canada.

Strategically located, the new parts distribution centre allows Doosan Infracore North America to provide both dealers and customers with better service options, deeper inventory and faster parts delivery, the company said.

The centre is located adjacent to the Doosan Infracore North America headquarters in Suwanee, Georgia, some 48 km northeast of Atlanta.

Edward Song, CEO, Doosan Infracore North America, said: “Doosan is committed to being a top-five construction equipment brand in North America and this new parts distribution centre illustrates our promise to support our dealers and our customers with parts availability and prompt delivery.” He said the company can “significantly reduce” shipping costs and can provide less than two-day delivery on a majority of its genuine parts delivered from the warehouse.

The facility, managed by leading contract logistics firm DHL Supply Chain, is designed for Doosan parts distribution and shipping. It will stock around 40,000 stock keeping units that can be shipped to service Doosan construction equipment throughout the US and Canada.

The parts distribution centre will house a majority of Doosan parts, with only some low-volume parts needing to come from Doosan manufacturing facilities around the globe, the company said.
Doosan supplies a variety of equipment to the mining sector including excavators and ADTs.

Terex TA400 ADTs stand up to Indonesia coal mine test

Ten Terex TA400 articulated haul trucks have been proving their worth removing overburden from a coal mine in East Kalimantan, Indonesia.

The trucks are being used by local mine owner PT Tambang Berkat Karunia for a five-year project in Batuah.

“We have the machines working for up to 18 hours a day, removing overburden and transporting it across the soft terrain,” said Bhisma Dian Resnadi, Operation Manager for PT Berkarya Abadi Selalu, a subsidiary of TBK tasked with undertaking the work.

The Terex Trucks TA400 is perfectly suited to perform in large-scale construction projects, quarries and mine sites, according to Terex. With a maximum payload of 38 t, TBK’s 10 TA400s can collectively haul 380 t, which is equivalent to the weight of around 70 Asian elephants.

“With the ground being so soft at the Batuah mine, we needed trucks that could perform in challenging conditions – and TBK’s TA400 haulers enable us to do just that,” Bhisma said. “Some of our operators had never used a TA400 before. They’ve said that they are very impressed with the performance features – especially the engine – as well as how advanced the technology is.”

Established in 2018, TBK is still relatively new to the industry. It purchased the Terex Trucks haulers from PT United Equipment Indonesia, the official Terex Trucks dealer in Indonesia since 2009.

Bhisma said: “We decided to go with Terex Trucks machines because they are known for being strong and reliable. Price factored into our decision, too. Given the quality of the TA400, the cost is very reasonable. As the project progresses, we might decide to purchase additional Terex Trucks haulers.”

The TA400 is powered by a six-cylinder Scania DC13 engine that is both fuel efficient and delivers low cost of operation, Terex says. It also comes fitted with a modulating transmission retarder, teamed with an efficient exhaust brake and fully enclosed oil-cooled multi-disc brakes, resulting in optimum control and increased safety.

In addition to this, all three axles are in permanent (6 x 6) all-wheel drive, which enables the TA400 to achieve great traction with minimal driveline impact and wheel spin. This results in reduced tyre wear.

To ensure servicing the TA400 is quick and easy, it comes with ground level test points and a fully tilting cab, as well as an electronically raised hood, which also results in reduced downtime.
