UNDERGROUND LOAD & HAUL manufacturer of battery powered underground mining equipment, and the core technology includes battery packs, electric motors, power electronics, software and control systems. The majority of battery loaders and trucks operating currently underground are powered by Artisan Vehicles technology.” He adds on the integration: “Today, Artisan Vehicles is a business unit within Sandvik Load and Haul division. The integration is in full speed at the moment, and more information about the way forward will be communicated later on. We will have both battery electric and cable tethered equipment in our offering also in the future, as alternatives for diesel powered load and haul equipment.” On the market for larger underground To expand its existing “intelligent” offering, Sandvik recently introduced its second i-series loader, the Sandvik LH621i machines, Scrivens said the focus of Sandvik is to increase the utilisation of the equipment to achieve higher productivity rather than just increasing the carry capacity of the machine. “For loaders and trucks, the existing tunnel size is the biggest limiting factor to increase the overall machine capacity. However, the use of Sandvik AutoMine increases the operating time of the loader or truck. Operation can continue quickly after blasting or during shift changes when normally manual operation has stopped. This increase the operating time of the loader or truck and overall productivity of the mine. But the mining customers are typically using the highest possible size and capacity machines for the tunnel size, and optimising the amount of individual equipment to increase the capital efficiency. Geology can also be a limiting factor regarding the bigger tunnel sizes.” To expand its existing “intelligent” offering, Sandvik recently introduced its second i-series loader, the Sandvik LH621i. “The LH621i is the loader of choice for rapid mine development and large-scale underground production, according to the company, and is a matching pair with the previously introduced 63-t payload Sandvik TH663i truck. The Sandvik LH621i sets the industry standard in the 21-t underground loader range.” It has been built on technology inherited from the Sandvik LH621, and now enters the market How focused are your reviews? .com Due diligence equipped with further improved features, according to the company. “With superior hydraulic power for fast bucket filling and drivetrain power for high ramp speeds, the Sandvik LH621i is designed to quickly clear tunnel headings for rapid advance rates,” Sandvik said. “Engineered with operator and maintenance personnel safety in mind, the rugged loader offers long component lifetimes and low costs per tonne.” The Sandvik LH621i features the latest Sandvik 16 International Mining | JUNE 2019
