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 a AC500 at the same time.
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 increase productivity at site as well.
Technical SpecificationsMost 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 a 1.2 metre wide track shoes for a narrower overal width, or a 1.5 metre wide track shoes for lower ground pressures, depending on site condition.
Ease of Transportation
The carbody is the largest single unit, measuring 3.5 metres wide and weighing 36 ton. The sideways outriggers are three metres wides and can be transported with its pads attached.
The counterweight is fitted a metres 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.
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.
