Liebherr said the order for four T 264 240t/265t trucks will increase MacKellar's fleet at Anglo American's Dawson open-cut metallurgical coal mine to nine - five more were ordered in early 2020.
"The T 264 provides efficient products for our clients by offering a true 240 metric tonne payload, and superior speed on grade," Mackellar Group noted in a statement.
The four new T 264, which will join the working fleet in early 2021, were manufactured in Liebherr Newport News facility in Virginia USA, but will complete pre-assembly in Mackay before travelling inland to Dawson Mine for final commissioning.
