Now that Demag is part of the Tadano Group the 156t telecrawler originally shown at Bauma 2019 is being relaunched as the Tadano GTC-1800EX telescopic boom crawler crane.
Tadano said that there are good reasons for including the telescopic boom crawler crane under the Tadano brand: Tadano has a long tradition with these products and a very strong line of telecrawlers. “Our goal is to become ‘One Tadano’. With the first telecrawler produced in Germany and branded by Tadano, this vision is now becoming a reality,” said Ingo Nöske, director product management, crawler cranes.
He added that this will strengthen cooperation between German and American colleagues in the Tadano Group in the future. The GTC-1800EX telecrawler has the Demag IC-1 Plus control as well as the IC-1 Remote telematics system technology. “With the integration of the GTC-1800EX into the Tadano brand, we’re bringing the lone warrior into the family, so to speak,” said Nöske.
The crane closes the gap between the 130t and 220t classes with an actual lifting capacity of 156t and a maximum load moment of 590mt. It has a track width that can be adjusted 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. “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,” Tadano added.
The crane can be used assist crane, as well as to carry out wind turbine pre-assembly work. It can lift a full 34t at a radius of 12m when working on an incline of 4° with the main boom at a length of 30m.
The main boom length of 60 meters can be increased further if necessary with lengths of 5m, 11m, 17m, and 23m which can be mechanically and hydraulically offset are available, giving a maximum system length of up to 83m.
The crane has different track widths with three standard positions of 3.5m, 4.75m and 6m, as well as the continuously variable track widths, which can also be used in an asymmetrical configuration. The tracks can be adjusted both when stopped and when traveling while the control system monitors the relevant parameters to ensure the crane remains within an allowable configuration.
The transport width and height of the base crane are three meters each and the heaviest transport unit weighs 47t. However this weight can be reduced to 42t by removing the extension beams used to adjust the track width. The two crawler units have a gross weight of approximately 18.5t each when equipped with one-meter track shoes; the two central ballast units weigh 7.5t each; and the counterweights, including the base plate, weigh 45t. The maximum operating weight of the crane is just under 150t.
The GTC-1800-EX crane is driven by an MTU 6-cylinder engine with an output of 230kW and a torque of 1,300Nm. This engine complies with EU Stage V specifications, as well as with Tier 4 Final specifications for the US market. At 1,500 rpm the diesel engine will run in an ECO mode that optimises fuel consumption, while at a speed of 1,800 rpm, it will have a Power Boost function available.
The primary and auxiliary hoists are technically identical, with both featuring a 245m, 26mm wire rope with a high line pull of 13.9t. The wire rope’s high line pull makes it possible to lift heavy loads with low reeving, saving time during setup and re-reeving.
