The new Tadano GTC-1800EX telescopic crawler provides unbeatable versatility.
The new GTC-1800EX tele crawler is an industry Leader Telescopic Crawler Crane in its class says Tadano. This is due to its ability to work on a 0°-4° incline without any limitation on positioning or compromise on lifting capacity due to optimised chart capacity calculations though our AC-1PLUS System.
The GTC-1800EX closes the gap between the 130 and 220-tonne capacity classes and has an actual lifting capacity of 156 tonnes and a maximum load moment of 590 meter-tonnes.
It has a track width that can be adjusted as necessary in both symmetrical and asymmetrical configurations so that it can be used for applications in which space is at a premium, such as bridge construction projects.
The tracks are available with one or 1.2 metre track pads and can be extended from 3.5 to six metres to the track centres. The overall track width with standard track pads runs from 4.82 to 7.32 metres. The tracks can be extended asymmetrically, to any position, with the crane’s intelligent control system based on the Demag control system IC-1 Plus, automatically calculating the load chart for the actual track width/configuration, slope and slew angle. The crane can pick & carry its full load chart.
Maximum counterweight is 45 tonnes on the superstructure and 15 tonnes on the carbody, while its maximum operating weight is just under 150 tonnes. The crane also has load charts for working on slopes of up to four degrees, at which it can handle 34 tonnes at a 12 metre radius with 30 metres of boom.
It is also perfect for construction work, where it is not only able to move and telescope components, but also luff down and retract the boom and then travel underneath roof structures to get to where it needs to be. In addition, the crane is also able to bring its strengths to bear as an assist crane, as well as when carrying out wind turbine pre-assembly work.
The load charts for its 60-meter-long main boom are excellent even when lifting on inclines of up to 4°.
The crane nomenclature suggests a 180 tonne rating with a maximum capacity of 156t at three metres. However, it has a maximum load moment of 590 metre/tonnes, which equates to a theoretical capacity of 180 tonnes at 3.2 metres, while the rest of the load chart is equivalent to a 160 to 180 tonne crane.
The crane has a six section 60 metre boom on which a five to 23 metre hydraulic luffing extension can be added with a luffing range from zero – in line with the boom – to an offset of 36 degrees. Intermediate lengths are 11 and 17 metres. Maximum tip height is 85 metres.
Tadano claim that the traction is best in class, with a true gradeability of 50 percent, with a maximum travel speed of 2.3kph and a ground clearance is 420mm. The transport width and height of the base crane are both three metres, while the heaviest transport unit weighs 47 tonnes. This can be reduced however to 42 tonnes by removing the extension beams used to adjust the track width. The two crawler units weigh 18.5 tonnes each, with one metre track shoes.
The crane can easily self-erect with jacks to lift it clear of a trailer and form a base from which to unload and install the tracks, with a standard counterweight installation system. In addition, most of the hydraulic couplings are quick connect, while the majority of the installation can be carried out form the operator’s cab which also tilts by up to 16 degrees. Plenty of steps and wide over the track walkways make this a great crane for access to the cab and the machinery compartment.
Power comes from a six cylinder Stage V/Tier 4 Final Mercedes engine. The crane has two operating modes with include an Eco mode at 1,500rpm – which optimises fuel consumption – and Power Boost mode with the engine at 1,800rpm. In this mode it provides a noticeable power increase allowing full simultaneous operation of functions at high power or speed. The two hoists are technically identical, with 245 metres wire rope stowage, and a 13.9 tonnes single line pull.
Integrated AC-1PLUS System to increase efficiency
The IC-1 Plus control system adds value to your crane by further increasing its flexibility, enabling it to perform more jobs. Live determination of the crane capacities, depending on the slewing angle of the superstructure and the capacity radar, allow multiple asymmetric outrigger setups for work in confined spaces – especially when lifting over the outriggers.
Transport costs are reduced, since you can use less counterweight compared with 360° capacities. Based on the field-proven IC-1 control system, standard on all Zweibrücken-made cranes, the system offers efficient and intuitive touchscreen operation and stores all load charts.
