Komatsu has released details of its latest heavy-duty demolition excavator – the 60-tonnes PC490HRD-11 model, designed with what their distributor in Ireland, McHale Plant Sales says is a ‘best in class’ working height.
Strong enough to lift a 2t demolition tool to a height of 32m, a 3.34t tool to 28m, or a 5t tool up to 17.4m, its operating weight ranges from 55.2t to 73.4t driven by a Komatsu EU Stage V-compliant engine delivering 270 kW / 362 HP at 1.900rpm, with minimal environmental impact.
Mindful of ecological concerns that govern the awarding of contracts – especially in low emission zones and urban projects – John O’Brien, sales director with McHale Plant Sales, sees the PC490HRD-11 as a machine that ‘will allow customers demonstrate their environmental credentials and participate in more tenders thereby future-proofing their investment’.
Highly versatile in a number of key respects, it features Komatsu’s own-designed boom change system. Oversized quick connectors for the hydraulic lines minimise back pressure and oil heating without restricting oil flow. Hydraulically powered pins, mounted inside the main boom structure, reduce damage risk. Its working range indication system means the machine can be operated to maximum effect through a full 360 degrees without compromising safety. Optional is a camera system located at the arm end that can display views of the working area to help avoid equipment damage.
Other elements amongst its array of features are a full colour cab screen displaying machine limits so operator keeps control at all times, KomVision surround view system, LED working lamps and a neutral gear detection system to help prevent unintended movement of the machine. As with all heavy-duty Komatsu machines, KOMTRAX telematics and Komatsu CARE maintenance support packages apply.
