Demag CC 2400-1

The Demag CC 2400-1 is a versatile 400-ton capacity crawler crane engineered for heavy-duty lifting in large construction, energy, and industrial projects. It boasts a maximum load moment of 5,168 t·m, making it suitable for demanding lifting applications where high capacity and reach are essential.

The crane’s crawler carrier includes a 3-section structure, consisting of a carbody and two side frames, which are pin-connected for easy assembly and disassembly. The frame is built from high-strength fine-grain structural steel, ensuring durability and stability during lifting operations. The tracks are powered by independent hydraulic motors with closed planetary gear units, providing smooth control and excellent mobility on various terrains.

The CC 2400-1 is powered by a DaimlerChrysler OM 501 LA diesel engine, delivering 260 kW (353 hp) at 2000 rpm. This engine drives a powerful hydraulic system equipped with variable displacement axial piston pumps that ensure smooth and precise control of the crane’s hoisting, slewing, and boom extension functions.

The crane offers multiple boom configurations, allowing for great flexibility in its operation. The main boom can extend from 24 to 126 meters, depending on the configuration. For example, the SH configuration provides boom lengths from 24 to 84 meters, while the SH/LH version can extend up to 108 meters. The crane also supports a Superlift system, which enhances its lifting capacity and stability during heavy-duty operations. With the Superlift system in place, the SSL/LSL configuration can reach boom lengths up to 126 meters, offering extensive reach for complex projects.

In addition to its boom configurations, the CC 2400-1 features luffing jib options ranging from 18 to 84 meters, further increasing its versatility and lifting height. The crane is also equipped with electronic load indicators, hoist and boom movement limit switches, hydraulic boom backstops, and anemometers to monitor wind speed, ensuring safe operation in all conditions.

The crane’s cab is designed for operator comfort and safety, featuring large safety-glazed windows, full instrumentation, air conditioning, and heating. The cab can be tilted for improved visibility during operations and folded for transport.

The Demag CC 2400-1 also incorporates the innovative IC-1 control system, which allows for touchscreen operation and provides real-time diagnostics and load monitoring to enhance operational efficiency. The Superlift equipment, which adds up to 240 tons of counterweight, allows for increased lifting capacities throughout its working range, making it ideal for heavy-load tasks across construction and energy sectors.

Optional equipment includes additional counterweights, Superlift configurations with variable radius adjustment, and jib extensions for more complex lifting tasks. With its strong lifting performance, advanced safety features, and flexible boom configurations, the Demag CC 2400-1 is an industry leader for large-scale lifting projects.

Variable Superlift And Boom Configurations

The superlift radius can be adjusted from 9 to 15 metres and in SWSL configuration, the main boom length is possible between 36 to 96 metres and fly jib length from 24 to 84 metres. In main boom, only SSL/LSL configuration, the maximum boom length is 126 metres. In main boom, only SSL configuration is 96 metres and where the superlift is position at 15 metres radius, the load chart shows that it can lift at a maximum radius of 80 metres, with 160 tonnes counterweight and central ballast, the CC2400-1 will lift 42 tonnes in 360 degrees.

On a 54 metres main boom, at a radius of 34 metres, the load chart shows a maximum lifting capacity of 140 tonnes. the maximum 400 tonnes lifting capacity in SSL is achieved with superlift at 12 metres radius with 42 metres main boom.

The complete machine, including its 100 tonnes of counterweight, 24m of boom and hook block weighs 233 tonnes. For transportation, the superstructure with three winches, hydraulic A-frame, car body and self-assembly equipment weights 59.6 tonnes each. Each crawler weighs 23.4 tonnes at 10.25 metres long and 1.3 metres wide.

The German manufacturer previous 400 tonner crawler crane was the Demag CC2400, last produced in the early 1990s.
