Leading Chinese underground LHD and truck OEM Qingdao Fambition Heavy Machinery will have a significant presence at the forthcoming BAUMA China event in Shanghai, being held 23-27 November – and this includes two new models, the diesel powered 22 t class FL225 and 15 t battery electric FL15B.
Beginning with the FL15B, Fambition states: “The electrification of underground mines is not only a change in power structure, but also a transformation in how equipment is operated. Charging efficiency, continuous operation time, energy consumption, and the underground working environment are all factors that mines need to consider when selecting electrified equipment. Better aligning charging time with operation cycles is a crucial part of electrification in underground mines.”
It says from charging efficiency to single haul speed and performance, the FL15B offers an electrified load and haul option tailored to the continuous operational needs of underground mines. It can operate for 7-8 hours on a single charge, with a 50 minute charging time and 6.3 m3 bucket capacity (SAE).
Fambition: “In underground mines, the power form of equipment not only affects energy usage but is also closely related to ventilation needs, maintenance management, and the working environment. Compared with traditional internal combustion underground loaders, battery underground loaders have different operational characteristics during use.”
Energy use is electrically driven, reducing dependence on diesel fuel, and providing a new solution for optimising the mine’s energy structure. Throughout underground operations, there is no diesel engine exhaust emissions, reducing the pressure for underground exhaust gas treatment and lowering the load on the ventilation system for handling diesel exhaust. The electrified power system eliminates the complicated maintenance of diesel engines and supporting components, offering better options for equipment operation and maintenance management.
The electric drive system also effectively reduces operational noise, and when paired with an ergonomic cab, it creates a more comfortable working environment for underground operators.
Moving on to the 22 t FL225 – Fambition says: “In underground mines, high-intensity material transfer places higher demands on equipment transport capacity, operational efficiency, and adaptability to working conditions. Limited drift space, complex transport routes, and continuous operational demands mean that equipment selection must consider not only rated loads but also comprehensive performance under actual working conditions.”
It says the FL225’s 22-t rated load capacity meets the demands of large capacity and high-intensity transportation in underground mines. It has a top speed of 27.9 km/h and can handle grades of up to 23%, with the bucket having a capacity of up to 10.7 m3.
The OEM concludes: “For underground mines, the overall performance of equipment not only affects single haul capacity but is also closely related to operational safety, continuous operational efficiency, and equipment reliability. The FL225 is designed to meet the operational needs of underground mines, seeking a reasonable match between equipment performance and practical applications, providing more options for high-intensity material transfer operations.”
