To expand its existing “intelligent” offering, Sandvik has introduced its second i-series loader, the Sandvik LH621i.

The LH621i is the loader of choice for rapid mine development and large-scale underground production, according to the company, and is a matching pair with the previously introduced 63-t payload Sandvik TH663i truck.

Sandvik said: “The Sandvik LH621i sets the industry standard in the 21-t underground loader range.”

It has been built on technology inherited from the Sandvik LH621, and now enters the market equipped with further improved features, according to the company.

“With superior hydraulic power for fast bucket filling and drivetrain power for high ramp speeds, the Sandvik LH621i is designed to quickly clear tunnel headings for rapid advance rates,” Sandvik said. “Engineered with operator and maintenance personnel safety in mind, the rugged loader offers long component lifetimes and low costs per tonne.”

The Sandvik LH621i features the latest Sandvik Intelligent Control System and My Sandvik Digital Services Knowledge Box™ on-board hardware as standard, providing product health monitoring and faster troubleshooting, according to the company.

The equipment has been designed automation ready, enabling the installation of Sandvik’s AutoMine® installation as a retrofit in just a few days. To improve comfort and productivity in manual operation, improvements have been made to the operator’s compartment, as the Sandvik LH621i features a more spacious and ergonomic cabin with increased visibility and 7 in (17.8 cm) touch-screen colour display.

“In the engine compartment, a fuel efficient 352 kW Stage II/Tier 2 engine deliveries powerful thrust for fast bucket filling and high-speed tramming for high productivity. A new, more powerful 375 kW Tier 4 Final/Stage IV low emission engine option is available with the use of ultra low sulphur diesel fuel,” the company said.

The diesel engine brake in the Stage IV/Tier 4 Final engine provides better control of vehicle speed downhill, minimising brake and transmission overheating and brake wear. Further, SHARK™ ground engaging tools are available on a wide range of bucket sizes, optimised for loader productivity and extended bucket service life.

Olli Karlsson, Product Line Manager, Large Loaders, Sandvik Mining and Rock Technology, said: “The new Sandvik LH621i competes in a space of its own. This new 21-t capacity loader truly represents a new breed of productivity and emphasises Sandvik’s capability to develop robust and efficient underground load and haul equipment.”

Sandvik’s i-series loader and truck family now includes two loaders and three trucks – the Sandvik LH517i, Sandvik LH621i, Sandvik TH545i, Sandvik TH551i and Sandvik TH663i.
