Aramine knows that one of the biggest issues in underground mining is the air pollution affecting people health.
To solve this issue, the company introduced its first diesel miniLoader® with an exhaust purifier several years ago but since then, the company has released a new model; an electric machine with a cable, which has already helped in reducing mine ventilation problems and cost compared to diesel machines. Marc Melkoinan, President of Aramine said: “The battery-powered machine was already in our mind but this technology was not enough reliable at the time and very expensive.”
Today, after two years of R&D, Aramine has a reliable and competitive product.
The machines were tested in customer mines before launching and are today in operation across a range of different mines.
The L140B was entirely developed and designed around a fully integrated battery system. Diesel fuel tank and filters but also hydrostatic transmission and related systems have been eliminated and a full electrical transmission has been integrated. This eases the maintenance and considerably reduces the downtimes.
As Aramine battery-powered machines are using an electric transmission, this allows adjusting the torque depending on the mine ground in order to give just enough power and avoid tires spinning. The L140B has same or even more breakout force than a Diesel machine.
The autonomy is approximately four hours depending on application and usage, which allows for the mucking of three to four faces in one shift.
The charging system is very simple as the charger is integrated into the machine and a simple plug to the wall is required. The charging system does not need a big electrical installation as the system only requires about 7kW of power (in comparison to the 45kW needed for an electrical machine with cable). An optional version features a quick disconnect battery module in order to replace easily the batteries and run the machine full time.
This new miniLoader® L140B is an optimised and advanced version of the L120B and can carry more capacity, 1.3 t. That is to say 20% more productivity per shift with the same autonomy and energy consumption.
“We really trust this battery powered innovation and customers are already seduced by the L140B proven by our order book” said Marc Melkonian, Aramine President.
