Demag CC2800-1 NT

As part of Demag’s plans to strengthen its position in the crawler market, they have introduced the CC2800-1 NT, a narrow track version of Demag CC2800-1 in 2006. With a chassis width of five metres, the crane was tailored especially for erecting of turbines at wind farms or sites that have restricted access. During the customer day, eight orders were placed with the first crane to be delivered already on shipment to Finland while the second unit, the crane at the event was due for shipment to Canada purchased by Guay Inc of Quebec, whom also ordered an AC500 at the same time.

Product Description

 

Taking into consideration for the windmill components erection in the mountainous areas, Terex has designed a narrow track version for the 600-tonne CC2800-1, the CC2800-1 NT. It is designed to travel down narrow roads, especially for windmill erection. Terex introduced a special car body to which the crawlers are connected. The side outriggers can be folded up so that when moving between locations and there are obstacles, the outriggers can be lifted up to reduce the crawler’s width. The articulated outrigger can be folded beside the crane to reduce the transport width significantly to 5.2m, travelling through in confined workspaces.

The narrow track chassis enables the crane to be moved, fully rigged, from one windmill to the next along the roads that are five metres wide. With the elimination of dismantling, transportation, and subsequent re-erection, it not only saves time but increases productivity at the site as well.

Most of the specifications of CC2800-1 NT is similar to CC2800-1, except with the addition of the Narrow Track Kit. The kit can be used either with 1.2-metre wide track shoes for a narrower overall width, or a 1.5-metre wide track shoes for lower ground pressures, depending on site condition.

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.
