50-tonne BEV truck combines best of two worlds

The new Sandvik TH550B 50-tonne battery-electric truck combines the best of two worlds: Sandvik’s half-century of experience designing and manufacturing equipment for the underground mining industry, and the innovative Artisan battery packs and electric drivelines. This combination of proven solutions and third-generation BEV (battery-electric vehicle) technology is a game changer for any site in pursuit of a more sustainable and highly productive fleet.

Rethink the machine, keep the same mine

Sandvik TH550B combines proven solutions and third-generation BEV technology. The truck has been designed to best utilize the innovative technology of its Artisan battery pack and electric driveline, enabling full leverage of the possibilities that the battery technology brings. Based on the philosophy of rethinking the equipment rather than the mine, the truck is simple to implement in any underground hard rock operation where a 50-tonne truck is required. Infrastructure needs are minimal, with no requirement for overhead cranes or other heavy handling equipment. All that is needed is a battery bay with an electric connection.

As battery equipment power is not constrained by mine ventilation limitations, the most powerful electric motors available can be utilized. The Sandvik TH550B electric drivetrain delivers 540 kW of continuous power, and 6,400 Nm of continuous torque output, allowing high acceleration and fast ramp speeds for shorter cycle times.

Fast and easy battery AutoSwap and AutoConnect

The patented self-swapping system of Sandvik TH550B, including the AutoSwap and AutoConnect functions, is designed for improved equipment availability and safety. Sandvik offers the fastest BEV pit stop on the market, taking only a few minutes. Sandvik TH550B disconnects and puts down the depleted battery, trams to pick up a new one, and automatically connects. During this quick and simple procedure, the truck operator controls the swapping without leaving the equipment cabin.

While tramming downhill, the truck uses regenerative braking to recharge the battery. For safety and reliability, the truck utilizes cutting edge battery technology, based on a  lithium-iron phosphate chemistry (LiFePO4 or LFP), a fit-for-purpose choice for underground mining.

Sandvik BEV loaders and trucks lining up

The Sandvik TH550B truck builds on its predecessor, the Artisan Z50, now tailored to include common Sandvik systems and design solutions to seamlessly fit the truck into the Sandvik product range. In addition to Sandvik TH550B, Sandvik battery-electric loader and truck offerings includes the 18-tonne LH518B loader as well as 4-tonne A4 and 10-tonne A10 from the Artisan line. Sandvik is continuing to develop additional battery-electric loaders and trucks in other size classes, including a 65-tonne battery truck in the near future.

Toro LH514BE with AutoMine merges automation, cable electrification and battery technology 

The Toro LH514BE, Sandvik’s new battery-assisted loader, is a unique combination of technology: an AutoMine compatible cable-electric loader, boosted with cutting-edge battery technology. This one-of-a-kind equipment leverages from the latest technologies.

Innovative power train technology for easy electric loader relocation and boost for ramp drive

The Toro LH514BE looks like a traditional electric loader while in operation, trailing cable connected to the mine electric grid, but the technology is not ordinary. When this loader needs to be moved to another area or to the maintenance bay, the difference is clearly visible: the power cable is disconnected from the electric grid. While the operator drives the loader to the new location, the Toro LH514BE gets its power solely from its battery. This battery-assist enables easy relocating and suitability for ramp drive.

Less heat, less CO2 – and no stops for refueling

One of the noteworthy features of the Toro LH514BE is the elimination of refueling or recharging stops. There is no diesel engine that would require fueling, and the battery does not need to be swapped because it is recharging during operation. The loader produces no exhaust emissions and significantly less heat than conventional equipment based on combustion, supporting mines in improving sustainability by reducing CO2 emissions. As a battery chemistry, the Toro LH514BE utilizes Lithium-Iron Phosphate chemistry (LiFePO4 or LFP) which is a fit-for-purpose choice for underground mining environments.

AutoMine compatible loader with built-in intelligence

The Toro LH514BE is available with Sandvik’s high-performing, robust and comprehensive automation system AutoMine. With AutoMine, a fleet of equipment can be converted into a high-performing autonomous production system, providing significant safety and productivity improvements for mine operations. The Toro LH514BE can be delivered with AutoMine, or the system can be easily retrofitted later during the loader’s lifetime.

As standard, the loader features Sandvik’s intelligent control system and a 7-in. touchscreen display, providing easy access to data. General battery health and status monitoring data as well as battery charge information is also available on the control system diagnostics. As usual in Sandvik’s large loaders, the integrated weighing system (IWS) option measures payload data and records the results to My Sandvik Digital Services Knowledge Box. The Knowledge Box transfers the data to the My Sandvik internet portal for visualization of fleet health, productivity and utilization. The OptiMine solution can also use transferred data for improving mining process efficiency.

Sandvik displays industry's largest battery-electric loader

Sandvik showcased what is considered the industry’s largest battery-electric loader at MINExpo. The 18-tonne Sandvik LH518B is the combination of Sandvik’s decades of engineering expertise and Artisan’s innovative powertrain technology and battery system proficiency.

Rethink the machine, not the mine

Launched in September 2020, the Sandvik LH518B has been designed, ground-up, entirely around the loader’s Artisan battery system and electric driveline to best utilize the possibilities that the battery technology brings. It was not enough to replace some components or redesign only a part of the equipment: by the designers rethinking the whole machine, a mine doesn’t need to rethink its infrastructure. In practice, changing the loader battery does not require any cranes or forklifts, thanks to the patented AutoSwap feature.

Unmatched productivity

The Sandvik LH518B delivers impressive capacity for its size: its design solutions allow the loader to fit in a 4.5 x 4.5 m tunnel and carry 18-tonne loads. In addition to an innovative boom and bucket system, the Sandvik LH518B features independent front and rear drivetrains, allowing high payload capacity while keeping a low overall height. For superior productivity, the Sandvik LH518B is equipped with three 2,000 Nm permanent magnet motors. With no torque converter, transmission or engine to rev up, the loader is fast and agile. There are no emission restrictions based on installed power to limit the electric motor selection, which enables the use of the most powerful motors available that are suited for the underground conditions.

Fast and easy battery AutoSwap and AutoConnect

The Sandvik LH518B is equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack. Battery swapping is fast and easy with minimal manual handling: changing the battery only takes about 6 minutes, and it can be done in a passing bay or old re-muck bay with no overhead cranes or external infrastructure needed. The new AutoConnect feature available for the first time on Sandvik LH518B is making swapping even easier and faster by automatically connecting and disconnecting the battery pack. Aside from unplugging and plugging in the charger, the operator doesn’t need to leave the cabin, which saves minutes on the swapping procedure and reduces effort and risk in the swapping process. The purely battery-powered loader reduces heat and emissions underground, helping mines reach their sustainability targets and reduce ventilation costs. The robust battery pack uses Lithium Iron Phosphate chemistry (LiFePO4) and is purpose-designed for use in underground mining.
