Doosan’s new Stage IIIB-compliant DX300LC-3 and DX340LC-3 crawler excavators are said to offer 6% to 17% higher productivity, along with fuel saving and reduced costs. The 30 and 35tonne machines have a new ROPS and OPG-certified pressurised cab. A heated air suspension seat and a new cab suspension cut vibration by 20% and reduce the sound level in the cab to 71d(B)A.
