Demag CC2800-1 NT

The Demag CC 2800-1 NT is a specialized variant of the CC 2800-1, specifically designed for narrow track (NT) applications. This crane features a robust design ideal for challenging environments like wind farms, where narrow paths and space constraints are common. The CC 2800-1 NT combines the power and versatility of its parent model with specific modifications to enable easier transport and maneuverability on narrow roads. The crane’s 600-tonne lifting capacity, paired with Terex’s Quadro crawler drive system, provides superior traction and control even on uneven terrains.

The crane’s narrow-track configuration includes a 3.8 m track width for the car body and outrigger pads designed to offer enhanced stability during operations. The front and rear outriggers, measuring 5 m x 1.4 m, and sideways outriggers, 3 m x 2.4 m, can be folded hydraulically to facilitate traveling. These features allow the crane to operate efficiently in tight spaces without compromising on load-handling ability.

The crane boasts excellent transport flexibility, with transport weights for individual components optimized to be under 39 tonnes. Its Superlift attachment and adjustable Superlift radius allow the crane to manage heavy loads and maintain stability across various lifting conditions. The CC 2800-1 NT also integrates the advanced Demag IC-1 crane control system, providing intuitive touchscreen-based controls, fault diagnostics, and real-time load monitoring.

In terms of performance, the maximum load moment is 6,140 tm, enabling the CC 2800-1 NT to lift up to 600 tonnes with ease, particularly when used with its Superlift system. Additional safety features include limit switches, load indicators, and hydraulic boom backstops to ensure safe crane operations. The narrow-track crane retains the flexibility to use either the 1,500 mm standard crawler pads or the optional 1,200 mm wide crawler pads for additional stability based on the job requirements.

This crane was first introduced to the market as part of Terex Demag’s strategy to cater to the growing demand for wind turbine installations and other projects requiring high lifting capacities in tight spaces. Its engineering and design allow operators to safely and efficiently erect large components in narrow, restricted environments, maintaining high lifting capacities and excellent mobility .

Ease of Transportation

The car body is the largest single unit, measuring 3.5 metres wide and weighing 36 ton. The sideways outriggers are three metres wide and can be transported with its pads attached.

The counterweight is fitted a metre lower than on a standard crane to keep the centre of gravity as low as possible to maximise lateral stability.

The unit can travel with boom configurations of up to 114 metres, with up to 2.4 degrees of lateral tilt approved by the manufacturer.

The CC 2800-1 NT can self-erect itself, with 102 metres of SH/LH SGLmax S7 boom and 12 metres luffing fly jib without an assist crane. Some other features include a low centre of gravity and low ground pressure. The superstructure of NT version is the same as the CC 2800-1 so it can still be converted into a standard crane.

Milestones

Brazil-based IMPSA Wind took delivery of the first CC2800-1 NT in Brazil on 2010

The crane was handed over to José Eduardo Teixeira de Carvalho Filho. They specialized in development and manufacture of the 1.5 to 2.1 MW wind turbines.
