Sandvik Mining and Rock Solutions has merged three of its established technologies into one loader with the Toro™ LH514BE. This loader is an AutoMine® compatible cable-electric loader, boosted with battery technology.
The Toro LH514BE, which IM first talked about in 2020, looks like a traditional electric loader while in operation, with a trailing cable connected to the mine electric grid, but the technology is not “ordinary”, Sandvik says.
“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,” the company explains. “While the operator drives the loader to the new location, Toro LH514BE gets its power solely from its battery. This battery-assist enables easy relocating and suitability for ramp drive.”
One of the noteworthy features of the new loader is the elimination of refuelling or recharging stops. There is no diesel engine that would require fuelling, 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, Sandvik says. As a battery chemistry, the Toro LH514BE uses lithium-iron phosphate chemistry, which, the company says, is a fit-for-purpose choice for underground mining environments.
The Toro LH514BE is available with Sandvik’s automation system AutoMine, which allows a fleet of equipment to be converted into an 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 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 visualisation of fleet health, productivity and utilisation. The OptiMine® solution can also use transferred data for improving mining process efficiency.
