Kobelco CKS1100

The Kobelco CKS1100 crawler crane, rated at 110 tons capacity, is designed to deliver reliable performance across a broad range of applications. It features a maximum crane boom length of 70.1 meters, with the ability to combine a 61-meter boom and 21.3-meter fixed jib, providing excellent flexibility and reach. Powering the crane is a HINO J08E-VM turbocharged, water-cooled diesel engine producing 213 kW at 2,100 rpm, with a maximum torque of 1,017 Nm at 1,600 rpm. The hydraulic system uses four variable displacement piston pumps supplying smooth, infinitely variable control to all winches, swing, and propel functions, with a maximum system pressure of 31.9 MPa for hoisting and propel systems.

The load hoist system includes front and rear drums, each grooved for 26 mm wire rope, with rated line pull of 108 kN and maximum line speed of 120 m/min on the first drum layer, ensuring efficient load handling. The swing system delivers a rotation speed of 3.2 rpm through planetary reducers and includes multiple-disc parking brakes. The crawler undercarriage offers retractable tracks and strong traction, with a maximum travel speed of 1.4 km/h and a gradeability of 40%. The operating weight of the crane is approximately 102 tons, including 34.6 tons of counterweight, ensuring solid stability even during heavy lifts.

Operator comfort and control are enhanced through a fully enclosed cab fitted with safety glass, air conditioning, and ergonomic seats. Advanced hydraulic and electronic control systems provide precise operation, while a self-removal device for counterweights and crawlers improves transport and rigging efficiency. The Kobelco CKS1100 embodies Kobelco’s commitment to safety, durability, and advanced engineering for demanding lifting tasks in construction, infrastructure, and heavy industry.
