NARROW VEIN & LOW PROFILE MINING
DUX Machinery ’ s narrow-vein mining equipment is in demand : the company is in the process of building three DT-26N dump trucks ( left ), while it has recently dispatched a P1-DBB14 boom truck ( right )
In addition to traditional fossil diesel fuel , the Stage V engine can use paraffinic diesel fuels , meeting the requirements of EN 15940 , which reduces emissions of CO , CO 2 , HC , NO x and diesel particulates . Further , these engines can also use biofuel blends ( such as FAME ) meeting requirements of EN 590 .
DUX machines in demand
A little bit bigger but still in the same market , DUX Machinery is in the process of completing
MEI Conferences
the build of three DT-26N dump trucks equipped with Cummins QSM11 engines able to supply 298 kW of power at 2,100 rpm for customers .

This 26-t payload truck has a bucket capacity of 11.4 cu . m ( heaped ), a length of 9.45 m and a
width of 2.29 m , making it the perfect fit for medium-high throughput narrow-vein operations .
It also comes equipped , as standard , with Bridgestone 18.00R25 , 2-star , E-4 VELS tubeless radial ( or equivalent ) tyres , a four-wheel POSI- STOP totally enclosed multi-disc , liquid-cooled , spring-applied hydraulically-released service / emergency parking brake , with its own independent circulating cooling system and accumulator back-up . It also has an automatic brake applicator that applies the brake in case of engine failure or pressure drop in the torque converter .
In terms of steering , it can rely on articulated frame hydraulic power steering with pilot monostick control . This comes alongside two double-acting steering cylinders with built-in cushion valves .
The DT-26N is equipped with articulated heavy-duty frames made to withstand the high impact and torsional stress associated with
mining applications , DUX says . The clean shell dump body is made from impact , wear-resistant alloy steel plates that substantially prolong service life , according to the company . It also allows for a 65 ° dumping angle .
DUX also recently shipped a P1-DBB14 boom truck , which shares the same platform ( engine , axles , transmission ) as the company ’ s DT-12 dump truck .
This aerial self-levelling boom truck can navigate narrow galleries with length and width dimensions of 9.1 m and 1.98 m , respectively . At the same time , it can reach the high levels operations require , with a boom extension able to support 454 kg up to heights of 9.3 m .
In the basket , operators have access to the full boom controls ( except stabilisers ). It also has two 180 ° pivot saddle devices on the basket for handling short and long pipes .
DUX said : “[ The ] spacious operator compartment is ergonomically designed for maximum visibility and bidirectional tramming , [ meaning the ] operator can safely control and monitor machine functions at a glance .”
Also , with centralised service points and a modular design , the P1-DBB14 offers easy service access and fast component exchange , according to the company . All of this is supported by service and parts back-up on a worldwide basis .
Reshaping a niche mining technique
Another company focused on the narrow-vein market that has recently been making headway with battery-electric drive options is Resemin .
The Peru-based company has made plans to offer all of its fleet with battery power , following the launch of its battery-powered jumbo , the Troidon 55-EV . This battery-equipped electric powered face drilling rig is designed for face drilling up to 39 sq . m . It is equipped with a single 75 kW electric motor for traction and drilling , and
