Kobelco's SK500LC weighs 111,800 pounds and has a bucket capacity of 2.48 cubic
yards. It features a 345-horsepower HINO engine. The machine is said to have top-
class digging forces, with a maximum bucket crowding force (with power boost) of
57,500 pounds. ECO mode controls the engine and hydraulic pressure to reduce fuel
consumption. Three modes — H (heavy workload), S (balanced workload), and ECO
(light workout and fuel savings) — are available. The manufacturer says the excavator
offers straight travel, which allows it to lift the rated lift chart while walking, to enhance
productivity and safety.
