Succeeding the CC 2800-1 model, the new Demag CC 2800-2 lattice boom crawler crane is just as versatile. It is suitable for infrastructure projects, including road and bridge construction, as well as for erecting wind turbines and refinery works.
According to Terex Cranes, several components of the CC 2800-2, such as the luffing jib or the middle main boom inserts, can also be used with the CC 2800-1. This enables customers to order the new CC 2800-2 only with the required components and therefore reducing the corresponding capital investment.
The basic unit of the CC 2800-2, on the other hand, was adapted to that of the CC 3800-1 and its strong drivetrain was included as well.
The CC 2800-2 offers a maximum lifting capacity of 600 t and maximum load moment of 7,712 tm. The length of its main boom is 102 m; in the Superlift LSL configuration, its boom length extends to 138 m, which can be once again increased with a luffing jib and the Superlift SWSL to a system length of 192 m. The main boom combined with the lightweight, rigid 12-m LH + LF extension reaches a length of 114 m, and with the Superlift system plus the mentioned extension, a total length of 153 m is possible.
The new CC 2800-2 is also designed for simple and efficient transport. For example, the A-frame and auxiliary hoist can be removed for transport and the SL mast, like that of the CC 3800-1, now consists of three (previously four) separate parts. The base crane, with a height of 3.195 m, weighs 77.1 t.
With the A-frame removed, the weight of the base crane is reduced to 62.6 t. The two frames used for the counterweight plates, instead of the conventional and significantly heavier base plates, also contribute to weight optimisation at 10 t each. The weight of the tracks was likewise optimised compared to the CC 2800-1. With the standard drive and 1.5 m track shoes, the total transport weight is 37.8 t; with the Quadro drive it is 41.5 t.
Moreover, the Demag CC 2800-2 is equipped with features that support the safe use of the crane. These include the ESTA-award-winning fall protection system for working at height, plus wide catwalks and platforms that ease walking access for inspecting and maintaining components of the crane.
The CC 3800-1 crane’s cabin is used in the new CC 2800-2. With a width of 1.55 m, an ergonomic and functional design that enables continuous fatigue-free work, standard air-conditioning and a CD-radio unit, the cab features excellent comfort. To ensure an efficient operation, the crane is also equipped with the IC-1 control system with two displays as well as two additional monitors that provide the operator with a continuous view of the hoists during operation.
For high efficiency on the jobsite, Demag offers the CC 2800-2 with all technical refinements. These include the Vario SL system for continuous, flexible adjustment of the Superlift radius from 11.5 to 15.5 m and the use of Split Tray.
The Split Tray allows for rapidly ‘disconnecting’ counterweight that is no longer required after the erection of the main boom, saving considerable time on the jobsite. The interchangeability of the counterweights among all Demag and Terex lattice boom crawler cranes in the 300-t-capacity classes and above also reduces costs for the crane owner.
The range of accessories of the new Demag CC 2800-2 is rounded off by the familiar Demag Superlift counterweight wagon, which facilitates moving the crane with the complete SL counterweight as well as the hydraulic telescoping connector for the adjustment of the Superlift radius from 13 to 17 m. Last but not least, the crane is also prepared for conversion to a narrower chassis with the Narrow Track Kit.
