According to International Cranes, crane manufacturer Terex-Demag in Germany will launch a new 400 tonne capacity crawler crane, the CC 2400-1. The new crane is being developed out of the Terex CC 2200’s crawler chassis and will have a completely new boom system, Terex-Demag said. The maximum load moment of the “world” crane, designed for all markets, will be at 5150 tonne-metres.
The features of the new crawler include a variable superlift radius, variable main boom offset in SW (heavy main boom and luffing fly jib) and SWSL (SW with superlift) configurations, and the touchscreen IC-1 control system. The superlift radius can be adjusted from 9 to 15 m. In SWSL configuration the main boom length is between 36 and 96 m and fly jib length is from 24 to 84 m. In SSL/LSL configuration the maximum main boom length is 126 m. In main boom-only SSL configuration it is 96 m. With superlift at 15 m radius the preliminary load chart shows a maximum lifting radius of 80 m. With 160 tonnes of counterweight and central ballast, the Terex CC 2400-1 crawler crane will lift 42 tonnes through 360 degrees. On a 54 m main boom, at a radius of 34 m, the load chart shows a maximum load of 140 tonnes. The maximum lifting capacity of 400 tonnes in SSL configuration is achieved out to 12 m on a 42 m main boom.
The complete crane, including 100 tonnes of counterweight, 24 m of boom, and hook block, weighs 233 tonnes. For the transport, the superstructure with three winches, hydraulic A-frame, carbody and self-assembly equipment weighs 59.6 tonnes. Each crawler is 23.4 tonnes, 10.25 m long and 1.3 m wide. The company’s previous 400 tonne crawler crane was the Demag CC 2400 that was last produced in the early 1990s. Deliveries of the new Terex CC 2400-1 are due to start early in 2006.
