Sandvik LH621i advanced underground loader

Toro™ LH621i is an intelligent and efficient 21 tonne underground loader, belonging to Sandvik Toro™ family.

Safer. Stronger. Smarter.

The Toro™ LH621i loader is engineered for rapid mine development and large-scale underground production. With superior hydraulic power for fast bucket filling and drivetrain power for high ramp speeds, this loader can quickly clear tunnel headings for rapid advance rates. Long-life components, specifically developed for the rough underground environment, contribute to low cost per tonne.

Designed with operator and maintenance safety in mind, the rugged loader is equipped with a quiet, spacious and ergonomic cabin. Smart placement of key service areas as well as multiple digital solutions offer easy maintenance access.
The Toro™ LH621i loader fuel efficient 352kW Tier 2 Volvo engine delivers powerful thrust for fast bucket filling and high speed tramming for high productivity.

When ultra-low Sulphur fuel is available, Sandvik offers Stage V and Tier 4f low emission engine options. The Stage V engine meets the relevant European emission regulations whereas the Tier 4f delivers significantly reduced MSHA and CANMET ventilation rates - still maintaining loader performance and fuel efficiency.

Toro™ LH621i features multiple smart solutions such as Sandvik Intelligent Control System, My Sandvik Digital Services Knowledge Box™ on-board hardware and AutoMine® readiness as standard. The Integrated Weighing System (IWS) is optionally available for measuring payload in the bucket as well as the number of buckets filled during a shift.

Toro™ LH621i is a matching pair with the Toro™ TH663i truck for three-pass loading.
