KOBELCO Construction Machinery USA, a crawler excavator manufacturer, has just introduced its enhanced SK500LC-10 model.
This excavator delivers a bucket digging force of 57,500-lbs and achieves 10% increase in work volume.
Equipped with an increased torque setting, the SK500 supplies 11% more digging volume than its predecessor.
Much of this boost in efficiency comes from a new hydraulic regeneration system which further minimizes energy loss.
The robust 114,000-lb SK500 is powered by a 369-hp Tier IV Final HINO engine, allowing it to easily tackle tough applications and remain highly fuel efficient.
A high-pressure common rail fuel injection system and variable-geometry turbocharger reduces particulate matter, while a large EGR cooler decreases NOx emissions by 80% to provide low operation emissions.
The KOBELCO SK500 also incorporates a new hydraulic drive to optimize the cooling fan rotation speed and deliver ultra-quiet operation.
