KOBELCO SK260SR LC-3 CRAWLER EXCAVATOR

Technical Description

The Kobelco SK260SR LC-3 is a heavy-duty hydraulic excavator engineered for high performance and durability in challenging construction environments. It operates with a robust 157 hp (117 kW) direct injection engine featuring a 312.7 cu in displacement and a max torque of 472.1 lbs-ft at 2000 rpm. The excavator has an operating weight of approximately 130,734 lbs and incorporates fuel-saving technologies along with an iNDr cooling system for enhanced efficiency. The undercarriage includes 51 shoes per side, an 8.5 ft track gauge, and delivers a drawbar pull of 54,600 lbs with a max travel speed of 3.5 mph and a gradeability of 70%. Three boom/stick configurations provide versatility: Option 1 offers arm crowd force (ISO) up to 27,201.9 lbs, bucket digging force up to 32,147.7 lbs, max digging depth of 20.1 ft, and max reach along ground of 30.1 ft. Option 2 reduces arm crowd force to 22,930.6 lbs but extends digging depth to 21.9 ft and max reach on ground to 31.9 ft. Option 3 further optimizes reach with a max digging depth of 23.1 ft, max reach on ground of 33 ft, but lowers arm crowd force to 21,491.8 lbs. Maximum cutting height ranges from 35.6 ft to 37.2 ft depending on the configuration. The hydraulic system delivers 116.3 gpm at a relief valve pressure of 4,970 psi with a fluid capacity of 60.8 gallons. The excavator features a compact tail swing radius of 6.2 ft, a minimum swing radius as low as 6.4 ft, and ground clearance of 17.9 in, optimizing maneuverability on confined job sites. Overall dimensions include a top cab height of 10.5 ft and an upper structure width of 9.1 ft. This combination of power, reach, and compact design makes the SK260SR LC-3 well-suited for diverse excavation tasks requiring strength and agility.
