UNDERGROUND LOAD & HAUL and specifications to Russia standards, organised the technological process: in-house production of the structural frame, arms and dippers, assembly of body parts, installation of components, start-up and commissioning of machines. Our next step will be the localisation of the production of lithium-ion batteries and the expansion of the product line with other types of underground equipment.” The first serial vehicles have already passed factory tests, according to ARMZ, and were sent to the uranium mines of PIMCU, PJSC in April 2020. In 2021, the ARGO LHD 140B will enter the Russia market and will then gradually become available in other countries within the customs union, it said. Fambition LHDs making waves in Chile and Peru China’s Qingdao Fambition Heavy Machinery Ltd, often referred to just as Fambition, has been one of the best known names among the country’s underground mining equipment OEMs for some years, but the company really took a step forward late last year when it delivered four 10 t (4 m 3 bucket) class FL10V LHDs to Codelco in Chile. Two of these machines have gone to work in the El Teniente Division underground copper mine and the other two at the Salvador Division underground copper mine. They arrived in October and November of 2019 and are the first Chinese LHDs to be used by Codelco. The FL10V is an LHD using FAMBITION™ technology that is designed for large scale underground metallic mine production, requiring a minimum drift width of 4.2 m. All key components are international wellknown brands including an DEUTZ engine, Kessler drivetrain, Dana converter drives and Parker hydraulic system which uses load sensing variable piston pump for higher efficiency and lower energy consumption. It applies CAN-bus technology with an onboard display to show real time operating parameters with self-diagnostics and troubleshooting. Peru-based Chao Zhang who heads up Americas sales for the company told IM that Fambition was chosen against other manufacturers, including other Chinese manufacturers, as it could offer the size class needed that matched the performance of the traditional major manufacturers but at a more competitive price and at the same time properly supported on the ground. Fambition has set up a new warehouse and office in Rancagua and has a team of ten people in the country including full time technicians at the mine. El Teniente's Maintenance Superintendent, Hernán Figueroa, pointed out at the handover ceremony of the first two machines that Codelco is very interested in generating business with China, as at the end of the day China is also the main client for its copper metal. From a machine point of view he said Codelco made this purchase because it believes that “they are quite competitive from the technical and economic point of view in our tasks. We have good expectations. The components are of good quality, the engine, the transmission, the axle, and we believe that it can be a reliable machine and that it can give a good result.” b Rodrigo Quiroz, Superintendent of Mine Engineering said: “This equipment on average is 20% cheaper in investment and what we want to prove is the added lower cost of maintenance and operation, where thanks to the agreements and commitments made we expect attractive results.” He also wants progress in terms of technology from Fambition going forward. “The arrival of the Chinese LHDs is the first step in a path that in the future should focus on electrical technology. It is part of a range of initiatives to move there and we have asked Fambition that if you want to continue with us you must push automation and electromobility. Thus, these machines in the future will be electric and autonomous, operated from Rancagua or from an office outside of the underground mine.” And a final note is that Fambition is not limited to Chile in the region, it has also recently set up an office in Lima, Peru in late 2019 with its own support team. Fambition has already had some LHD sales in Peru and says it looks forward to further building relationships with customers in the country as well as in the wider Americas region. IM China’s Alpha developing new remote control LHD It is estimated that there are now at least ten OEM agnostic companies in China offering levels of automation of underground load and haul equipment from teleremote up to full automation. One of them is Alpha Industrial Intelligence Holding Co Ltd, a Chengdu-headquartered group with an additional location in Kunming plus a base in Sydney, Australia. As an example of its projects, as early as 2011 it deployed a line of sight teleremote system at the Caijiaying gold and zinc mine on two SINOME ACY-3L LHDs. The mine used backstoping blasting starting with a slot raise at one end of the stope, and retreating blasting at both ends. For safety reasons, a significant part of the ore remained in the most distant part of the blasted areas could not be removed, which was resolved with this solution. Moving to the present, Alpha now offers autonomous solutions across all machine brands but also told IM that it is also developing its own TLHD-WJ-2D diesel LHD, which it says adopts the most advanced manufacturing standards. It has two operation modes of vehicle local control and remote control, which are flexible and optional to ensure operation safety in dangerous areas. Through the built-in sensor, the operation status data of the LHD is also uploaded to the Alpha Cloud Intelligent Maintenance cloud to enable data fault diagnosis and predictive maintenance of the LHD. The LHD is being assembled at the Techgart Tianjin factory (Techgart is a shareholder of Alpha) and it is expected to be launched in July 2020. It is powered by a reliable Deutz engine and the bucket was produced with full machine automatic welding and is made of NM500 wear-resistant steel in the high wear parts, extending the service life. The gearbox has four gears for forward and reverse operation, which can efficiently adjust the power requirements. Various sensors are installed on the equipment to monitor the running status in real time. An LCD screen on the remote transmitter can display signals and feedback with error alerts as well. Sensors follow engine parameters: oil pressure, engine temperature, engine speed; hydraulic parameters: hydraulic oil pressure, brake pressure, hydraulic oil; as well as fuel tank level, travel time, engine operating status, braking state etc. Fambition delivered four 10 t (4 m 3 bucket) class FL10V LHDs to Codelco in Chile in late 2019 Alpha's new TLHD-WJ-2D diesel LHD offers remote control and IoT condition monitoring 18 International Mining | JUNE 2020
