Demag CC 1500

The Demag CC 1500 is a high-capacity crawler crane designed to handle challenging lifting operations with a rated capacity of 300 tons. The crane’s design incorporates a 3-section carrier, including the carbody and two crawler side frames, providing excellent stability and mobility on-site. The crawlers are powered independently by hydraulic motors, allowing for precision control and smooth maneuvering, even in difficult terrain. The hydraulic pin connections between the crawlers and carbody make assembly and disassembly easy for transportation.

The crane’s superstructure is built from torsion-resistant fine-grain structural steel and includes a powerful DaimlerChrysler OM 501 LA diesel engine, generating 260 kW (353 hp) at 2000 rpm. The engine complies with EURO II/EPA standards, providing reliable and efficient power for lifting operations. The pump distribution gearbox includes five variable displacement axial piston pumps, enabling precise control over the crane’s functions.

The CC 1500 features a wide range of boom configurations, including SH, SH/LH, SW, LF, and SSL, which offer different lengths and capabilities depending on the specific application. The main boom can be extended from 18 to 102 meters in various configurations, with additional fly jibs available for increased height and reach. The crane’s boom and jib components are made from high-strength lattice-type tubular chord structures, ensuring durability and flexibility. For instance, the SH/LH configuration allows for a boom length of 42 to 102 meters, while the SW version includes a luffing jib option, reaching up to 72 meters.

The crane is equipped with two rope drums as standard—one for the hoist and one for the boom lift—each powered by hydraulic motors with closed planetary gear units. This ensures reliable hoisting performance, with spring-applied multi-disc brakes and hydraulic braking for secure load management. Additionally, the crane’s slewing unit operates through a hydraulic motor for smooth, controlled rotations.

The CC 1500’s cab is designed for operator comfort and safety, featuring large safety-glazed windows, full instrumentation, and heating. The cab can be tilted for better visibility and can be removed for transportation, minimizing width. The crane’s control system includes an electronic proportional valve pilot-control, allowing operators to monitor and adjust crane movements with precision. Safety features include electronic load indicators, limit switches for hoist and boom movements, and an anemometer for wind monitoring.

Optional equipment includes an additional rope drum for a second hoist, auxiliary winches, and additional counterweights to enhance the crane’s performance in larger or more demanding projects. The crane’s counterweight can be expanded up to 120 tons, ensuring stability during heavy lifts.

Overall, the Demag CC 1500 is a robust, flexible crawler crane that combines powerful lifting capabilities with advanced engineering, making it ideal for use in construction, infrastructure development, and heavy industrial projects.

Milestones

Franz Bracht taken delivery of Europe’s first CC1500 in 2003. – The CC1500 went straight to work on its first job after being handed over to Franz Bracht at the INTERMAT exhibition in May 2003. The 275-tonne crawler is being used to lift precast concrete components weighing up to 75 tonnes each, as part of the construction of a new UPS cargo centre at Cologne airport. In order to avoid interference with the airport radar, the crane is rigged with 36m main boom and maximum 120 tonnes of counterweight and 20 tonnes of central ballast. In addition, to overcome the height restriction, a specially designed attachment is used to allow the concrete piles to get as close to the boom head as possible.
