BATTERY AND ELECTRIC VEHICLES
process equipment such as explosives charging, spraying, lifting and installations; and the L-series is engineered for heavier transport and material handling tasks.
While the XS-, M-, and L-series platforms are purpose-built to address different payload capacities and operational requirements, each platform serves as the common foundation across its respective series offering of applications. This enables multiple application configurations built on shared components and systems, delivering flexibility while supporting efficient maintenance and streamlined fleet management, Normet says.
Medium-section niche
RESEMIN, the Lima-based manufacturer of underground drilling equipment, has unveiled its latest innovation in the BEV space: the e-TROIDON 55. Developed in Peru, this compact jumbo is specifically designed for medium-section mining, featuring a narrow 1.85 m width and a highperformance HC95 21 kW drifter. components. At the heart of the jumbo is a NMC battery system with an installed capacity of 77.7 kWh. Engineered to comply with rigorous international safety protocols and standards, the battery pack is designed for high-demand cycles, featuring a 1C charge rate and a 2C discharge rate.
To maximise availability, RESEMIN has integrated three on-board battery chargers. This configuration optimises energy management throughout the operational cycle, ensuring that once the operator finishes a face, the unit is fully prepared for immediate transit to the next work area, significantly minimising idle time, the company says.
Following successful field trials at a Peruvian mine – where it demonstrated reliable results in both tramming and drilling – the jumbo is now ready for global deployment.
Engineered to handle the unique geographic challenges of high-altitude mining, the unit operates efficiently at up to 4,500 metres above sea level. Furthermore, all components are rated for extreme conditions, with a functional temperature range from-30 ° C to 45 ° C. This makes it a versatile solution for underground operations in diverse climates, from the Andean peaks to extreme thermal environments.
Currently, the company is working on further upgrades to the platform and plans to deploy the machine to additional international locations. These upcoming trials will focus on refining energy efficiency and charging capacity to meet the evolving needs of the zero-emission mining sector.
Scaling up with strength
Talking of niches, Aramine has eyes on breaking out of its narrow-vein fortes, with an expanding battery-electric offering being a big part of that.
The company, which celebrated its 50th anniversary last year, started its BEV journey in 2016 with the incorporation of the L140B miniLoader, which has gone on to sell more than 45 units. This was soon followed by the 4.6 t-payload L440B truck. The second of these trucks was delivered to Grecian Magnesite last year as part of a plan to help its Koutzi mine, which already had a L140B in operation, reach its circa-50,000 t / y design capacity of pre-concentrated magnesite.
Marc Melkonian, co-President in charge of the Equipment Division, told IM that there has been significant international demand for this BEV platform.
“ The first L440B delivery went to Canada with NORCAT, followed by a second machine delivered in Greece,” he said.“ The positive results from this first installation in Greece have already led to a new order in the country.”
The next L440B will also be delivered to Greece, where it will be commissioned at a new underground mining project for a different customer, according to Melkonian. Following this, another unit is scheduled for South America and a further delivery is then planned again for Europe.
“ This sequence illustrates the strong international interest in the L440B and reflects the growing momentum behind battery-electric solutions for underground mining operations,” he added.
Reflecting on this BEV success, Aramine is thinking bigger and broader when it comes to its next vehicles.
“ The first step toward larger machines builds directly on the proven platform of the L440B,” Melkonian explained.“ By integrating larger axles, wheels and a bigger bucket, the machine evolves into the L640B, offering a payload capacity of 6.2 t. In addition, replacing the loader frame with a dump frame allows the platform to become a 13-t payload battery-electric mine truck, perfectly matched to operate alongside the L440B loader.”
The e-TROIDON 55 is built around highefficiency permanent magnet electric motors, each dedicated to a specific function to maximise operational output, Resemin says
The machine is built around highefficiency permanent magnet electric motors, each dedicated to a specific function to maximise operational output. A 133 kW motor powers the tramming system, while a separate 100 kW motor is dedicated exclusively to drilling. To ensure reliability in any environment, an advanced thermal management system uses a glycol-water mixture to maintain optimal operating temperatures for all critical electronic
The L440B has registered strong international interest, according to Marc Melkonian International Mining | APRIL 2025
