While matching the dimensions of the Cat R1700G, the new loader has an increased payload of 15t, 20% more than the predecessor.

According to Caterpillar, a recent head-to-head study and multiple field trials show that the machine leverages its payload advantage to deliver faster truck loading and more productive load-and-carry operations, while also using less fuel per hour.

"The R1700 gains cycle-time advantages through fast bucket loading due to high breakout forces and a new traction control system that limits tyre slip when the bucket enters the pile," the manufacturer said.

"The result is fast loading, good bucket fill factors and reduced tyre wear. Excellent machine balance and a new electrohydraulic braking system aid load-and-carry cycles."
Fuel efficiency can be enhanced with the on-demand adjustment of the machine's cooling fan and hydraulic system.

The 6-cylinder Cat C13 engine is turbocharged and air-to-air aftercooled, and it produces 269kW in standard configuration and 257kW in EU Stage V compliant form.

The engine is available in three different emissions configurations: Cat Ventilation Reduction, US EPA Tier 3/EU Stage IIIA, and EU Stage V. This means the loader can be tailored to the ventilation needs of the mine.

Optional Autodig on the loader can help new operators be productive the first day and reduces fatigue for experienced operators.

MineStar Command for underground, on the other hand, offers a selection of control technologies, including line-of-sight remote control, teleremote control from a distant operator station, semi-autonomous operation, and fully autonomous operation.
