Liebherr has unveiled a new six axle 400 tonne All Terrain crane this morning at its Customer Days in Berg near Ehingen, Germany.
The new 400t LTM 1400-6.1
the LTM 1400-6.1 will replace the popular 350 tonne LTM 1350-6.1 and will feature a similar six section 70 metre boom to the LTM1350, including Y-Guy Superlift system, but with major improvements including a simpler single lift set up and a hydraulic quick coupling system that closes automatically when the boom is lowered between the two Y-frames. The electrical connection is established with one final movement, allowing it to go into operation in just a few minutes.
Jibs & extensions
Various lattice extensions and jibs are available, starting with the manual or hydraulically luffing 45.5 metre extension that takes the maximum tip height to around 120 metres and can offset by up to 40 degrees. An 80.5 metre luffing jib, takes the maximum tip height to around 140 metres.

Single engine concept
Unlike the 350, the LTM 1400 is single engine model, it also features VarioBase outrigger set up with load charts automatically calculated for outriggers fully retracted, with free extension positions up to 50 percent extended, then 75 percent and fully extended. A new VarioBallast adjustable counterweight system extends the tailswing from a compact 5.6 metres out to 7.7 metres for maximum capacities. The basic counterweight is 100 tonnes, with an additional 40 tonnes available. The counterweight slabs are the same as fitted to other large Liebherr All Terrain cranes.

For road travel the crane has an overall length of 17.8 metres and can meet 12 tonne axle loads with the full boom and a hook block on board. On site or where 16.5 tonne axle loads are permitted it can carry the boom, 10 tonnes of ballast, a hook block and Y-guying system on board.
Checking the chassis cab
Other features include driver assistance for road travel including a ‘Blind Spot Information System’ which warns the driver when someone is in the vehicle's blind spot, particularly when turning, while a moving-off information system provides a visual and acoustic warning if someone is in front of the crane, while monitoring the areas around the crane while it is moving.
