Tadano has announced that it will launch a longer boomed version of its five axle 250 tonne AC 5.250-2 at Bauma. The new crane - the AC 5.250L-2 - will have a 79 metre eight section main boom, compared to the seven section 70 metre boom on the current 250. The 5.8 to 30 metre lattice extensions take the maximum tip height to 112 metres.
The new model was announced at the pre-Bauma press event yesterday and is said to be largely the same as the regular model, but with the longer boom. That probably oversimplifies it a little, but we have yet to see the full specification sheets. In terms of road travel, it is much the same as the standard model.

In spite of the extra boom section, the new crane can still meet 12 tonne axle loads with the 10 x 6 drive and 16:00 wheels, outriggers, 32 tonne extension brackets, a Vario hook block, and 250kg of gear onboard.
Where 16.5 tonne axle loads are permitted with a total weight of 82.5 tonnes, the AC 5.250L-2 can even be driven on public roads with a 10 x 8 drive, outriggers, a 12 metre extension, 500kg of rigging, a 32 hook block and also 20 tonnes of counterweight.
Project manager Peter Kleinhans said: “Our AC 5.250L-2 is also top of the class when it comes to load moment at 736 tonne/metres. This high load moment is achieved at a radius of seven metres, on a 13.5 metre main boom and a 105.2 tonne load. In addition, we offer an optional heavy lift attachment for loads up to 138.7 tonnes on the short boom with additional sheaves. And thanks to the standard IC-1 Plus crane control system, the possible radius can be increased considerably in certain areas of the slewing angle.”
The company will also unveil a new 1,250 lattice crawler at Bauma, in fact the crane is already being assembled as the show's CCTV cameras show:

Great to see the 1250t Crawler at last.
