New Demag CC 2800-2 crawler crane at bauma 2019
When a manufacturer replaces a successful model with its successor, customer expectations are extraordinarily high. This is also true of the new Demag® CC 2800-2 lattice boom crawler crane, which is continuing the legacy of its enormously successful predecessor Demag CC 2800-1. The manufacturer’s concept: continuing to develop proven products and further improving performance with innovative technical solutions.
Like its predecessor, the new Demag CC 2800-2 is extremely versatile: it can be used for infrastructure projects in road and bridge construction as well as erecting wind turbines, and puts in a fine performance in refineries too. Thus, it fully lives up to the reputation of the Demag CC 2800-1 – but the new kid on the block does everything even better than its predecessor, as its transportability was optimized and its handling surpasses that of the older model. Particularly interesting for owners of Demag CC 2800-1 cranes: several components such as the luffing jib or the middle main boom inserts can be used with the successor as well. 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, on the other hand, was adapted to that of the CC 3800-1 and its strong drivetrain was included as well.
With regard to the performance and the technical specifications, the CC 2800-2 is at the top of its class: Its maximum lifting capacity is 600 tonnes and its maximum load moment is 7,712 tonne-meters. The length of its main boom is 102 meters; in the Superlift LSL configuration, its boom length extends to 138 meters, which can be once again increased with a luffing jib and the Superlift SWSL to a system length of 192 meters. The main boom combined with the lightweight, rigid 12-meter LH + LF extension allows for a length of 114 meters, and with the Superlift system plus the mentioned extension, a total length of 153 meters is possible.
Optimized transport and handling
The new CC 2800-2 crane was consistently 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 meters, weighs 77.1 tonnes. With the A-frame removed, the weight of the base crane is reduced to 62.6 tonnes. The two frames used for the counterweight plates, instead of the conventional and significantly heavier base plates, also contribute to weight optimization at ten tonnes each. The weight of the tracks was likewise optimized compared to the CC 2800-1. With the standard drive and 1.5 meter track shoes, the total transport weight is 37.8 tons; with the Quadro drive it is 41.5 tons.
With fall protection system for safe work at height
Like all Demag cranes, the new Demag CC 2800-2 crane is equipped with features which support the safe use of the crane. These include the ESTA-award-winning fall protection system, an excellent feature for working at height. Other features include 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 model. With a width of 1.55 meters, an ergonomic and functional design that enables continuous fatigue-free work, standard air-conditioning and a CD-radio unit, it offers excellent comfort. To ensure a high level of 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.
Comprehensive range of accessories
To achieve a high degree of efficiency on the construction site, Demag offers the CC 2800-2 crane with all technical refinements. These include the Vario SL system for continuous, flexible adjustment of the Superlift radius from 11.5 to 15.5 meters and the use of the Split Tray. The Split Tray in particular, which allows for rapidly “disconnecting” counterweight that is no longer required after the erection of the main boom, saves considerable time on the construction site. The interchangeability of the counterweights among all Demag and Terex lattice boom crawler cranes of the capacity classes 300 tonnes 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 meters. Last but not least, the crane is also prepared for conversion to a narrower chassis with the Narrow Track Kit.
