Tadano has announced the introduction of its new 60 tonne, three axle AC 3.060-2, All Terrain crane. It is available to order now with deliveries expected to begin later this year in the Americas and Australia. Those units will be built in Japan alongside its current two axle domestic model.
Production of the first European units is expected to get underway in the first half of next year, with deliveries coming shortly thereafter.
The new AC 3.060-2 features a 50 metre six section main boom and is rated at 2.5 metres, at three metres radius it can handle 39.5 tonnes. Capacity on the fully extended main boom is 6.7 tonnes at a 12 metre radius.
Maximum tip height is 69 metres
An 8.5 to 16 metre bi-fold swingaway extension can be added for a maximum tip height of just under 69 metres. When offset at 40 degrees it has a capacity of up to 2.4 tonnes at a 64 metre tip height and 16 metres radius or 26 metres radius at a 60 metre height.
The crane has up 13 tonnes of counterweight, but can be rigged with 9.8, 4.2 or 3.1 tonne counterweights. Maximum single line pull is 6.7 tonnes. When rigged with three falls on a single sheave hook block it can handle 20 tonnes.
On the road with 12 tonne axle loads
The six wheel drive, all wheel steer crane can travel within 12 tonne axle loads with 4.2 tonnes of counterweight on board plus the single sheave hook block and 300kg of slings and rigging. Or 3.1 tonnes of counterweight, the full extension and 400kg of rigging. Alternatively where 16.5 tonne axle weights are permitted the crane can travel with everything on board plus half a tonne of rigging etc..
The overall width is 2.55 metres, overall height 3.71 metres, and overall length is 11.69 metres although the chassis length is just under 9.5 metres. Outrigger spread is variable between 3.0 and 6.5 metres with the ‘Flex Base’ monitoring an automatic load chart set up and IC-1 Plus crane control system with capacity radar.
Outrigger set up is independently variable
The Tadano four camera ‘Surround View’ system is optional, as are winch cameras and the e-Pack battery electric power pack for working indoors.
Masafumi Nakamura a member of the product development team at Tadano Japan said: “With our new AC 3.060-2, we have created a compact and powerful crane that can cover an extremely wide range of applications without much effort. That was our development goal – and we have definitely achieved it. This strong performance with a steep boom angle proves particularly advantageous when lifting heavy loads over obstacles.
Vertikal Comment
While this crane looks visually quite similar in many areas to the old Demag based AC 3.060-1, we understand the changes are profound. It certainly has the longest main boom with at least two metres more than its rivals, while its lattice extension is longer or as long any of the others.
In capacity terms it lacks some capacity in the close-in structural part of the load chart, which is virtually unusable, apart from when hooked up to a load test dynamometer. Throughout the rest of the load chart, it performs very well.
The Grove GMK3060L can carry a bit more counterweight within 12 tonne axle loads, but the new Tadano strikes a good balance between this and the Liebherr LTM 1060-3.1.
Producing the first units in Japan is an interesting move, with a very weak yen to dollar exchange rate it makes sense financially, while whether we like it or not, Japanese production lines typically tend to turn out a better built product.
Perhaps Tadano is starting production in Japan first in the hope that it can then transfer all the build quality and mentality to its German plant next year.
In summary this looks like a winner.
