Sandvik has introduced the LH621i intelligent loader for large-scale underground production and mine development.

To expand its existing intelligent offering, Sandvik has added the second i-series loader to its range.

The LH621i, designed for rapid mine development, is matched with the previously introduced Sandvik TH663i truck, considering the designed payload capacities of the two machines.

Sandvik LH621i is the latest addition to the 21-tonne underground loader range. It has been built on the technology inherited from its predecessor, Sandvik LH621, and enters the market equipped with improved features.

With superior hydraulic power for fast bucket filling and drivetrain power for high ramp speeds, Sandvik LH621i is designed to quickly clear tunnel headings for rapid advance rates, according to the original equipment manufacturer (OEM).

Engineered with operator and maintenance personnel safety in mind, the rugged loader offers long component lifetimes and low costs per tonne.

Sandvik 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 as a retrofit in just a couple of days.

To improve comfort and productivity in manual operation, significant improvements have been made to the operator’s compartment. Sandvik LH621i features a more spacious and ergonomic cabin with increased visibility and a seven-inch touch-screen colour display, among others.

In the engine compartment, a fuel efficient 352kW Stage 2 / Tier 2 engine delivers powerful thrust for fast bucket filling and high-speed tramming for high productivity.

A more powerful 375kW Tier 4f / Stage 4 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, minimising brake and transmission overheating and brake wear.

The Shark Ground Engaging Tools (GET) are also available on a wide range of bucket sizes, optimised for loader productivity and extended bucket service life.

“The new Sandvik LH621i competes in a space of its own. This new 21-tonne 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 Mining and Rock Technology product line manager, large loaders Olli Karlsson says.

Sandvik’s i-series loader and truck family now forms a full house of intelligent equipment with two loaders and three trucks: Sandvik LH517i, Sandvik LH621i, Sandvik TH545i, Sandvik TH551i and Sandvik TH663i.
