EFFICIENT TRANSPORTATION
Automatic self-assembly, automatic levelling and compact dimensions ensure efficient assembly and transport.
The GTC-2000 is optimized for transport. The base crane is transported to the site on a low-bed truck, the crane components separately on several standard trucks. This means that separate driving permits are not required in most cases. This also means that the GTC-2000 can get to the worksite faster – and get to work on lifts that would not be feasible otherwise.
OPTIMAL WEIGHT DISTRIBUTION
The 51.8 tons base crane has compact dimensions. These dimensions − 10 feet wide, 10 feet high − make it easy to transport. In addition, it is possible to reduce the weight of the base crane from 51.8 to 46.3 tons. The crane components are carried on standard trucks, independent of the base crane. The separately transported components include: both crawler carriers, 2 central ballast elements, and the counterweights with base plate. Thus, the maximum dead weight of around 165 tons can be optimally distributed. And thanks to the flexible transport concept, separate driving permits are unnecessary in most cases. The 16.4-foot jib can also be folded to the main boom making transport even easier.
The 47 t base crane has compact dimensions. These dimensions − 3 meters wide, 3 meters high − make it easy to transport. In addition, it is possible to reduce the weight of the base crane from 47 t to 42 t . The crane components are carried on standard trucks, independent of the base crane. The separately transported components include: both crawler carriers, 2 central ballast elements, and the counterweights with base plate. Thus, the maximum dead weight of around 150 t can be optimally distributed. And thanks to the flexible transport concept, separate driving permits are unnecessary in most cases. The 5-meter jib can also be folded to the main boom making transport even easier.

POWERFUL DRIVE TRAIN
Performing well in rough terrain is a core quality of excellent crawler cranes. This requires three things: high traction force, robust track design and extreme maneuverability. The GTC-2000 combines all three – and adds significant ground clearance, excavator-like driving characteristics, extremely flexible track widths and high lifting capacities on uneven ground.
SETS NEW STANDARDS
Thanks to its powerful drive, including a 230 kW MTU EU Stage V engine, the GTC-2000 has exceptional traction force: 1450 kN, clearly outperforming the competition.
No less impressive are the other values, including gradeability of up to 50 percent and a maximum travel speed
of 2.1 km/h (1.3 mph).
IMMEDIATE TRACK WIDTH ADJUSTMENT
If the terrain changes, the crane operator can change the track width – immediately, easily, flexibly. The track widths can be adapted to the requirements of the terrain – continuously variable – as easily while driving as when stationary. In addition, the track widths can be adjusted symmetrically or asymmetrically.
PEAK PERFORMANCE
172 US tons lifting capacity, 196.9 ft main boom and a wide selection of boom extensions.
156 tons lifting capacity, 60 m main boom and a wide selection of boom extensions.
Main boom length: 196.9 feet. The GTC-2000 has the longest reach in its class. But that’s not all: The extensions of 16.4 ft – 75.5 ft enable a system length of up to 272.3 ft and can be offset – either mechanically with offset angles of 0°, 18° and 36°, or hydraulically – even under load – from 0° to 36° (stepless). Extremely practical for work on site: With the jib luffed down and the main boom retracted, nothing stops the crane from driving under structures like bridges, for example.

FLEXIBLE COUNTERWEIGHT
No matter what loads need to be lifted or moved and how strong the main booms are: There is no way around a balanced concept for central ballast and counterweight stack. Especially if the setup is reliable and a misconfiguration is immediately detected.
CENTRAL BALLAST
The crane operator can assemble the two 7.5-tonne (8.3 tons) central ballasts for the carrier from the cab using the crane or, optionally, entirely by remote. As per the poka-yoke principle – which avoids the incorrect installation of individual parts through their geometric properties and dimensions – the two central ballasts are mechanically designed so as to prevent mix-up during setup. A sensor confirms the installation
COUNTERWEIGHT STACK
The two options also apply to setting up the counterweight stacks on the central ballast: the crane operator takes this into his own hands with the crane, or controls the process via remote control. In any case, there is no additional work at height. Because the operator or the riggers do not have to secure the counterweights on the superstructure. The counterweights are mechanically locked on the crane superstructure using automatic hydraulic cylinders. This connection enables the reliable, robust operation of the GTC-2000, even in rough terrain. The counterweight of 45 t (49.6 tons) is stacked with the help of slings – in one lift or in a total of 5 lifts. The amount of counterweight is automatically measured to ensure this process also runs without errors.
