REPOWERING MOUNT THORLEY

LIEBHERR-AUSTRALIA MADE HISTORY AT YANCOAL'S MOUNT THORLEY WARKWORTH COAL OPERATIONS IN NOVEMBER 2024.

Just because an engine reaches the end of its life doesn't mean the whole machine has to.

At least that's what the Yancoal maintenance team decided when it contracted Liebherr-Australia to repower two R 9800 excavators at its Mount Thorley Warkworth (MTW) coal operation in the New South Wales' Hunter Valley.

Repowering in the context of mining machinery means upgrading the existing engine with a newer, more efficient one – and that's exactly what Liebherr-Australia did.

The repower involved replacing the existing engines with Liebherr's D9812 12-cylinder engines, designed specifically for the mining industry.

The project marked the first repower of Liebherr R 9800s in the world, highlighting Liebherr's engineering expertise and customer-centred care.

Liebherr began the process at its Mount Thorley facility, where the company prepared the D9812 engines for integration. Once complete, they were transported to MTW where the final phases of the repower were executed to ensure a smooth transition into operation.

A testament to teamwork

Mount Thorley service manager Ben Carlyle said the teamwork, attention to detail and care of the customer service team were crucial to the project.
