Min­ing con­trac­tor Downer Min­ing has re­cently added a Lieb­herr R 9800 BH min­ing ex­ca­va­tor to its op­er­a­tion at Queens­land’s BMA Goonyella mine.

The mon­ster Lieb­herr R 9800 BH joins Downer’s fleet of four R 9800 BH ex­ca­va­tors and four

R 9400 ex­ca­va­tors. The enor­mous shov­els are be­ing used in both coal and iron ore ap­pli­ca­tions.

The big Lieb­herr R 9800 BH has an op­er­at­ing weight of around 810 tonnes with the face shovel at­tach­ment, or 800 tonnes in back­hoe mode.

Downer Min­ing has been in op­er­a­tion for more than 90 years and pro­vides min­ing ser­vices at all stages of the min­ing life­cy­cle. One of the group’s cur­rent projects is the op­er­a­tion of the Goonyella River­side Mine in QLD’s Bowen Basin.

The R 9800 BH ex­ca­va­tor is a se­ri­ous min­ing ma­chine de­signed for large-scale op­er­a­tions.

The Lieb­herr is pow­ered by two US Tier In­terim/ EU Stage IIIB Cum­mins QSK 60 en­gines ca­pa­ble of push­ing out an as­ton­ish­ing 2984kW.

Both the face shovel and back­hoe at­tach­ments can hold up to 42 cu­bic me­tres of ma­te­rial at a rated weight of 1.8 tonnes per cu­bic me­tre, for a to­tal of 75.6 tonnes of ma­te­rial per pass.

The gi­ant dig­ger sits atop a heavy-duty un­der­car­riage that fea­tures au­to­matic track ten­sion­ing and an ex­ter­nal travel drive.

The R 9800 BH’s cab is in­su­lated against sound and vi­bra­tions and has a body-con­toured pneu­matic seat that can be ad­justed to the op­er­a­tor’s weight. The ex­ca­va­tor’s joy­stick levers are fully integrated into the arm­rest, which can also be ad­justed to match the seat po­si­tion.
