NHL driving ahead new know-how mining vans in China with international market potential

Posted by Paul Moore on twenty ninth June 2024

At The Electrical Mine 2024, Internal Mongolia North Hauler Joint Inventory Co Ltd (NHL)’s Guojun Dong, its VP of Finance & Head of Worldwide Division, gave a deep dive into the Baotou-based mining truck main’s progress with new vitality hauler options. He co-presented with Roy Zou, Group Vice President – Worldwide Division at accomplice Alta Know-how, which manufactures traction management programs and supplies electrical management programs and infrastructure for a lot of of those new mining truck options; constructing on its extensive expertise within the excessive velocity rail business.

Dong went into some element on NHL’s fairly exceptional progress to date in supplying battery electrical, hybrid and hydrogen mining vans in China – arguably when it comes to what it has really achieved it’s additional forward than every other OEM in these future know-how rollouts. That that is taking place in China is probably comprehensible given the huge market measurement – over 1,200 open pit mines in China alone. Plus it’s also being pushed by the ever better authorities concentrate on greener mining.

“Here’s what we now have completed and what we now have deliberate for the brand new vitality. You possibly can see to this point we have already got the 50 ton, 65 ton, 100 ton and 130 ton electrical vans which have already been delivered to prospects.” These are the TR50E, TR56E, TR100E and TR130E. He added that NHL sees the market as having a requirement for the TR200E and TR240E vans and that these tasks are into account. In the present day NHL works primarily with CATL for battery provide, utilizing lithium iron phosphate chemistry, plus works primarily with Cummins on engines and Wabtec with electrical wheel motors.

Trying again on its electrical mining truck expertise from a timeline viewpoint, this dates all the way in which again to 2013 and its supply of six NTE330T trolley help diesel vans to Swakop Uranium’s Husab mine in Namibia, that are nonetheless working as we speak. Its TR50E battery truck was developed again in 2015 and as we speak round 100 of those are working with buyer Conch Cement at its limestone mining operations with one other 50 at different buyer websites. NHL additionally constructed a TR65E battery truck in 2022 and the TR100E in 2023 of which 50 have now been equipped together with many items to Conch Cement. The NTH35 hybrid truck was in-built 2018. Greater than 15 NTE130E battery vans have now additionally been equipped to the market and it’ll produce the NTE150E by end-2024. Battery trolley choices are additionally beneath improvement.

The expertise within the cement business with the TR100E lately has been very constructive – reaching over 110,000 t/y of manufacturing with every truck working over 16 hours operation per day and doing over 55 journeys per day. Static charging takes lower than 50 minutes.

Then he moved on to hybrid vans. Curiously it began with a really small mannequin, the NTH35, in 2018 to show out the know-how however has adopted this up with the ultraclass NTH260 which was developed in shut partnership with Cummins and was not too long ago delivered to the client Baogang Group’s Baiyun iron mine, for trial operation. The companions are additionally properly superior with an NTH100E mannequin.

He mentioned the NTH260 (payload 236 t) with its ‘battery help drive’ brings gasoline financial savings of as much as 20% so lowers gasoline value by over US$210,000 per 12 months. Plus it means diminished upkeep prices, prolonged overhaul cycle and improved operational effectivity. Carbon discount is as much as 20% so a reduce of over 540 t per 12 months.

Subsequent up hydrogen vans – FCEVs. Final 12 months a 136 t class (150 ton) NTH150 was delivered to Huolinhe coal mine. IM understands that it has been performing properly – although working hours are lower than 1,000 – the problem with hydrogen vans is similar as elsewhere on the planet – associated to infrastructure. There’s no low cost resolution of compressed hydrogen storage at website and supply for now, the price of a neighborhood resolution is excessive, so extra progress can be made when the price of compressed hydrogen is low sufficient for the operation. It is usually not but sure whether or not the Chinese language market will shift in direction of simply battery electrical or additionally hydrogen and as such the OEMs – like NHL but additionally quantity two XCMG – are hedging their bets and providing each choices.

Dong emphasised that prospects within the Chinese language market need a totally inexperienced ‘package deal’ resolution and confirmed an fascinating ecosystem graphic exhibiting inexperienced energy era then energy equipped to charging stations and onto battery vans then another of inexperienced energy to hydrogen manufacturing by electrolysis of water, hydrogenation after which provide to hydrogen vans.

On the subject of autonomy, NHL along with companions like TAGE Idriver has delivered greater than 260 autonomous vans to greater than 20 open pit mining websites with a 100% repurchase fee. This contains Julong Copper, a part of Zijin Mining, at over 5,455 m altitude.

A last be aware on the long run – by the tip of 2024 NHL is trying to have prepared an autonomous, 136 t (150 ton) class cabless truck – the AT150 Good Battery Truck. It should have 4 wheel steering, double A-arm nitrogen suspension, V2V communication, and could have twin powertrain choices – a battery pack or a diesel engine. Prospects in China are eager to trial the most recent applied sciences and choices so there isn’t any scarcity of mines desirous to trial the brand new prototype.
