Doosan Bobcat EMEA has launched the DX160LC-5 HT and DX180LC-5 HT Stage IV compliant high track crawler excavators.

They complement the company’s standard configuration DX140LC-5 14 tonne and DX180LC-5 18 tonne mid-range excavators. Doosan says that the DX160LC-5 HT excavator combines the upper structure from the DX140LC-5 14tonne model with an 18 tonne class high track undercarriage system, increasing the ground clearance from 410 mm in the DX140LC-5 to 615 mm.

Similarly, the DX180LC-5 HT is an enhanced version of the DX180LC-5, incorporating a reinforced structure and a re-engineered, high-performance braking system. This machine, too, offers the same ground clearance of 615 mm, compared to 460 mm in the DX180LC-5.

They are part of Doosan’s new generation LC-5 range of machines meeting the latest Stage IV emissions regulations. Both are powered by the Perkins 1204F engine, which combines reduced fuel consumption with the power and torque of larger engines with a smaller displacement. The P1204F engine provides 81.6kW in the DX160 and nearly 95kW in the DX180 at 2000 rpm.

The Perkins engine also uses an electronically controlled, high-pressure common-rail fuel system (2000 bar) – which reduces particulate matter emissions from the cylinder – and a wastegate turbocharger.
