Further expanding its intelligent line of equipment, Sandvik announced its second i-series loader, Sandvik LH621i. The company said it is the loader of choice for rapid mine development and large-scale underground production. The new high-capacity loader matches well with the previously introduced Sandvik TH663i truck.

“The new Sandvik LH621i competes in a space of its own,” said Olli Karlsson, product line manager, large loaders, Sandvik Mining and Rock Technology. “This new 21-ton capacity loader truly represents a new breed of productivity and emphasizes Sandvik’s capability to develop robust and efficient underground load and haul equipment.”

Sandvik said the LH621i has been built on proven technology inherited from its market leading predecessor, the Sandvik LH621. The new machine now enters the market equipped with further improved features, such as improved hydraulic power for fast bucket filling and the drivetrain power needed for high ramp speeds. The loader is designed to quickly clear headings for rapid advance rates.

The LH621i features the latest Sandvik Intelligent Control System and My Sandvik Digital Services Knowledge Box on-board hardware as standard. The equipment has been designed automation ready, which makes the unit flexible, enabling Sandvik’s AutoMine installation also as a retrofit just in a couple of days. To improve comfort and productivity in manual operation, significant improvements have been made to the operator’s compartment, as the Sandvik LH621i features a new more spacious and ergonomic cabin with increased visibility and a 7-in. touch-screen color display, among others.

In the engine compartment, a fuel efficient 352kW Stage II/Tier 2 engine delivers thrust for fast bucket filling and high-speed tramming. A new, more powerful 375kW Tier 4f/Stage IV low emission engine option is available with the use of Ultra Low Sulphur Diesel Fuel. The diesel engine brake in the Stage IV/Tier 4f engine provides better control of vehicle speed downhill, minimizing brake and transmission overheating and brake wear. Further, Shark ground engaging tools are available on a wide range of bucket sizes.
