Product Description

The Kobelco CKE900G crawler crane is engineered to deliver dependable performance across a broad range of construction and industrial lifting tasks. With a rated lifting capacity of 90 tons at a 3.4-meter radius, this crane offers exceptional versatility through its boom and jib configurations. The main boom extends from 12.2 meters up to 61 meters, while the fixed jib can be combined up to 51.8 meters of boom plus an additional 18.3 meters of jib, providing impressive reach for complex lifting operations.

Under the hood, the CKE900G is powered by a HINO J08E-UV six-cylinder, turbocharged, water-cooled diesel engine, producing 213 kW at 2,100 rpm and delivering maximum torque of 1,017 Nm at 1,600 rpm. The engine meets stringent EU Stage IIIB and US EPA Interim Tier 4 emission standards, ensuring environmental compliance and fuel efficiency.

The hydraulic system employs three variable displacement piston pumps and a full-flow control system that responds instantly to operator commands. The load hoist, boom hoist, and propel systems operate at pressures up to 31.9 MPa, while swing functions are supported at 27.5 MPa. High-capacity hydraulic (440 liters) and fuel (400 liters) tanks enable extended operational periods.

The crane’s main and auxiliary winches feature large-capacity drums and 26 mm diameter wire ropes, offering rated single-line pulls of 112 kN and maximum line speeds of 120 m/min. The boom hoist drum is grooved for 16 mm rope and achieves smooth speeds ranging from 2 to 70 m/min. A robust swing system driven by dual planetary reducers provides 360-degree rotation at 4 rpm, with hydraulic multi-disc brakes ensuring safe load handling.

The undercarriage is designed for rugged performance and ease of assembly, featuring hydraulic track tensioning, sealed track rollers, and 800 mm wide shoes. It achieves a maximum travel speed of 1.73 km/h and a gradeability of 40%, distributing its 90-ton operating weight at 101 kPa ground pressure for excellent stability.

The operator cab is fully enclosed with safety glass, equipped with air conditioning, ergonomic controls, high-backed adjustable seating, and excellent visibility. Safety features include external drum ratchets, swing locks, and robust boom backstops, adhering to EN13000 standards.

Overall, the Kobelco CKE900G is built to handle demanding lifting applications with efficiency, precision, and operator comfort, making it an ideal choice for mid- to large-scale infrastructure, industrial, and general construction projects.
