operation. Transport weight is 60
tonnes, with a 12 tonne axle load
including 13.2 m boom extension
and 25 tonne hook block.
One of the biggest design
advantages of an all terrain is
flexibility, being able to drive
on public roads and off-road
on site. The 3-axle Liebherr
60 tonne LTM 1060-3.1 is also
designed to meet demands for
roadability. It has a total weight of
36 tonnes and includes 5.5 tonnes
of counterweight, 48 m telescopic
boom and 16 m folding jib; hoist
heights are up to 63 m and radii is
up to 48 m when used with folding
jib. “To offer the widest range of
driving conditions, in particular at an axle
load of 12 tonnes, a special ballast plate
configuration has been implemented in the
design,” says Beringer. “Depending on the
crane equipment and the required vehicle
payload, the ballast carried may be 3.7
tonnes, 4.3 tonnes, 4.9 tonnes or
5.5 tonnes.” For countries without the
12 tonne axle load restriction, the
LTM 1060-3.1 drives at approximately
15 tonnes per axle with maximum ballast of
12.8 tonnes.
Being able to work in small and
restricted spaces on job sites is another
factor that manufacturers are taking into
consideration. The new Grove GMK3060,
for example, has a 43 m boom on a 3-axle
carrier, and has been designed for lifting
jobs in tight locations. It is an upgraded
version of the GMK3055 and has an
additional 2 tonnes of counterweight.
A recent introduction from
manufacturer XCMG in China is the
QAY1200. The 1,200 tonne capacity
9-axle AT crane has a twin engine design
and an 8-section telescopic boom. It
has 5-axle drive and all-wheel steering.
“The QAY1200 can be widely adopted in
lifting installation operations in energy,
transportation, petrochemical and other
major projects,” a spokesperson from
XCMG says. In addition, the crane can self-
disassemble its boom and counterweight.
Also new from China is the Zoomlion
QAY260. More details will be reported
when available.
Looking ahead
Looking further ahead in the development
of all terrains, manufactures are focusing
on emissions legislation. “While this
process is continuing to demand a lot
of engineering hours, we are looking at
other new features and will bring these in
where it makes sense,” adds Astrid Hager-
Guthrie at Manitowoc. In addition, as
wind and nuclear power projects continue
to be developed, especially in China, it is
expected that in the next five years higher-
tonnage all terrain cranes will also
be developed.
