New Cat® AD45 underground truck

Global Mining Review,

The new Cat® AD45 Underground Mining Truck is available in emission standard-meeting configurations. With a payload of 45 t, the new truck is a three-pass match to the Cat R1700 underground loader.

The new AD45 has improved speed on grade of its predecessor, the AD45B, and it has the same dimensional envelope even when configured for minimal exhaust emissions.

The AD45 is powered by the Cat C18 engine. The 6-cylinder engine is turbocharged and air-to-air aftercooled, and produces 439 kW in standard configuration and 447 kW in EU Stage V compliant form.

Using the proven company’s clean emissions module to limit both particulate matter and NOx to near zero, the AD45 is certified to meet EU Stage V (equivalent to US EPA Tier 4) and is approved by CANMET for use in underground mines. The module uses selective catalytic reduction with diesel exhaust fluid injection and a diesel particulate filter. The engine and emissions module are proven in millions of hours of operation. The Stage V compliant engine configuration is also available to repower AD45B models currently in the field.

Two additional emissions packages are available for the AD45. One has emissions equivalent to Stage IIIA and Tier 3. The second is Caterpillar’s ventilation reduction system, which incorporates modified engine hardware and software as well as the optional use of a flow through diesel particulate filter for improved underground air quality.

The company’s mechanical drive power train and power shift transmission provide control on steep grades, in poor underfoot conditions and on haul roads and drives with high rolling resistance. The company’s seven-speed planetary power shift transmission is matched with the direct-injection C18 engine to deliver constant power over a range of operating speeds.
