The Cat® R1700 Loader

Flagship LHD for Underground Mining

More Powerful - Stage V  Capable - Increased Payload  

A clean-sheet redesign, the R1700 loader leverages engineering talent from across Caterpillar to bring new levels of productivity, operator comfort, and service convenience to our customers. The R1700 is Stage V emissions capable and technology-enabled direct from the factory, carries 20% more material with each pass, and is highly aggressive in the pile. It is also a very quiet and well-balanced machine.

Our new traction control system drastically limits tire slip going into the pile, which resulted in our field trial test mines seeing a significant cost savings on tires. Also, its Autodig helps new operators be productive the first day and reduces fatigue for your experienced teams. Plus, we’ve designed in safety features like operator presence and door latch monitoring for their added protection.

All new levels of power and performance for the R1700 loader start with the engine. Where the R1700G made good use of the power from the C11, this new machine and its performance goals demanded more – so we moved up in size to the C13 ACERT™. The C13 ACERT is a heavy-duty performer with an in-line, 6-cylinder configuration that is turbo-charged and air-to-air aftercooled.

Aftertreatment for the Stage V engine configuration is chassis mounted for convenience and includes a Diesel Emission Fluid (DEF) tank sized to match the 12-hour capacity of the fuel tank. Regeneration can be set to automatic – the operator is informed when regeneration is happening, and the machine takes care of the process while continuing to operate.

Longer Life, Less Replacement Time

Complementing the new R1700 is a new bucket design and a new family of Ground Engaging Tools that bolt on. Our Bolt-On Half-Arrow (BOHA) line conveniently eliminates welding underground, limits waste material, and in some cases, can provide extended life in abrasive, hard material.
