Komatsu has introduced a new Tier 4 Interim/Stage IIIB wheeled excavator in the shape of the PW160-10 that it claims offers a fuel consumption that has been reduced by up to 8% against the model it supersedes. Weighing in at 17 to 18.5 tonnes depending on configuration, Komatsu claims that the PW160-10 offers faster cycle times with a heavier counterweight, excellent stability and an "over the side" lifting capacity improved by 8%. Power comes from a Komatsu SAA4D107E-2 engine with a net output of 110 kW (148hp) at 2.000 rpm.
The integrated design of the new Komatsu Diesel Oxidation Catalyst (KDOC) allows this simple system to remove soot using 100% “true passive regeneration”, without the need for a Diesel Particulate Filter (DPF). The KDOC is designed for long life and has no scheduled replacement interval.
Engine management was improved on the PW160-10 and the hydraulic system updated with a new main control valve (cartridge type). Easier to replace and with hardened internal parts, this hydraulic valve simplifies maintenance with an increased component life time.
According to Sebastian Zienau, product manager for wheeled excavators: “Thanks to industry-leading characteristics, such as its superior lifting capacity, outstanding stability and upgraded driving performance, the productivity of the PW160-10 can equal that of a higher class machine. The operator works in a perfectly safe environment and gets more done, faster, at a lower cost with total peace of mind.”
