Kobelco CKE600G

Built for dependable performance and versatility, the Kobelco CKE600G crawler crane offers a maximum lifting capacity of 60 tons at a 3-meter working radius, with a crane boom length that extends from 9.1 meters to 51.8 meters. The welded lattice boom design, constructed of high-tensile tubular steel with pin connections, ensures durability and ease of assembly or transport. For additional reach and flexibility, the crane supports fixed jib combinations of up to 39.6 meters plus 18.3 meters, accommodating diverse site requirements.

The crane is powered by a HINO J08E-UV turbocharged, water-cooled six-cylinder diesel engine producing 213 kW at 2,100 rpm and a peak torque of 1,017 Nm at 1,600 rpm. Complying with European Stage IIIB and US EPA Interim Tier 4 standards, the engine is designed for efficient fuel use and reduced emissions. Three variable displacement piston pumps in the hydraulic system provide smooth, precise control for hoisting, swing, and travel functions, with maximum system pressures of 31.9 MPa. The hydraulic reservoir holds 440 liters, while the fuel tank capacity is 400 liters, allowing for extended operation between refueling.

The crane’s load hoisting system includes front and rear winches grooved for 22 mm wire rope, offering rated single-line pulls of 78.5 kN and maximum line speeds of 120 m/min, supporting rope lengths of 180 meters on the main and 130 meters on the auxiliary drum. Wet-type multiple disc brakes and external drum ratchets provide additional safety and secure load handling. The boom hoist system, also hydraulically driven, operates at speeds ranging from 2 to 70 m/min using 16 mm rope.

Swing operations are powered by dual hydraulic motors driving planetary reducers, enabling 360-degree continuous rotation at 4.5 rpm. Multiple-disc spring-set, hydraulically released brakes ensure stable swing control and safe operation during transport with a manual four-position swing lock system.

Crawler assemblies are hydraulically extendable, featuring 925 mm wide shoes and sealed track rollers for reduced maintenance and improved durability. The crane achieves travel speeds of 2.3 km/h (high) and 1.5 km/h (low), with a maximum gradeability of 40%. Operating weight is approximately 46.1 tons including a 13-ton counterweight, and ground pressure is maintained at 63.1 kPa for stable operation.

The operator cab is fully enclosed and equipped with safety glass, air conditioning, ergonomic controls, and enhanced visibility, delivering comfort and precision for the operator in demanding work conditions. Additional features include robust steel-welded carbody construction, external boom backstops, and optional self-removal devices for counterweights and crawlers, improving transport and rigging efficiency.

The Kobelco CKE600G combines solid lifting power, flexible boom and jib configurations, and advanced hydraulic control, making it a reliable choice for infrastructure, industrial, and general construction lifting applications.
