CRAWLER CRANES Ӏ SECTOR REPORT
j the batteries. It is therefore
zero-emission and fossil-fuel free (assuming your electricity source is sustainable).
The machine not only
helps save the planet, it is also quieter than its diesel-powered counterparts and operates with less vibration. Electric motors have the added benefit of greatly reducing service requirements:
Tadano’s
renamed GTC-2000 telecrawler
maintenance procedures such as engine oil changes are completely eliminated. Also on show at Bauma will be a smaller electric crawler, of 6t capacity, the CC 1485 from Maeda. It is powered by an electric drive made by Deutz; Maeda have produced electric spider-cranes before now, but this is their first cooperation with Deutz. The German company is a pioneer of carbon-neutral drive systems for off-highway applications and is steadily expanding its range. The CC 1485 is a small teleboom pick- and-carry with a 360-volt drive powered by a 40 kW lithium-ion battery. Full production is expected to begin in 2023. Tadano produces both teleboom and lattice boom crawler cranes, in several different capacities. Over the years the nomenclature and model numbers of these has become somewhat idiosyncratic; units produced in the US bore names different to those of identical units produced elsewhere. Last autumn (2021) Tadano moved to rectify this for its latticeboom crawlers; this summer it has announced similar harmonisation for its telebooms. Models sold on the American market will keep their existing names and numbering; those sold elsewhere will change to the US nomenclature. Thus the Tadano GTC-350EX will be called the GTC-350; the GTC-500EX becomes the GTC-500, and the GTC-600EX will become GTC- 700. The changes will come into effect later this year, though the company’s newest model, the 156 tonne capacity GTC-1800EX telescopic boom crawler, which was introduced in November 2020 and is built in Zweibrücken gets its new name with immediate effect. It is now, officially, the GTC-2000. Tadano explain this exception as based on an upgrading of

the crane to the 200-tonne class: “Customers kept telling us that their experience in the field showed that in several configurations, the GTC-1800EX had a performance potential that far exceeded its [180t] class,” said product manager Vincent Stenger. “Therefore, we are renaming the model to the GTC-2000 for all markets to better align the name with the crane’s lifting capacities.” For existing GTC-1800EX models in the field, Tadano will offer customers a kit to upgrade these cranes to the GTC-2000. The upgrade does not require any structural changes, but it does require a software change, with new load charts for a fixed position with no slew, and one for up to 180 degrees slew. It also includes new crane documentation, manuals, decals and nameplate. Tadano plans to exhibit the GTC-2000 telescopic boom crawler crane at Bauma 2022 this October. One frequent application for
the GTC-1800EX, or the GTC- 2000, (or even the Demag TTC 160 as the machine was actually originally named back in 2019 when it was first designed and produced by Demag before that company merged with Tadano), is on windfarms. Crawlers generally are in high demand for this ever- growing application. The reasons are not hard to find. High capacity and high boom and under-the- hook heights comes near the top of the list, with manoeverability not far behind. For example, wind power is an application that Sany suggest for its largest telecrawler, the SCC1300TB. Introduced in June 2020, the 130t-capacity machine has a 60 metre boom in six sections with an 18.1 metre fixed jib; its maximum load moment is 4,800 kN-m. Pick and carry capability, says Sany, is 50 per cent higher than comparable
