round up
We have already covered the Bauma
introductions in detail. Here though is some
information and images of a number of late
breaking products.
Spierings City Boy
Spierings new City Boy - SK397-AT3 -
mobile self erecting tower crane is
still under construction as the team
race against the clock to complete
it. We now have a much better
indication of what it will look like
and a few more details on its
capabilities. Not only is this new
three axle single cab crane more
compact than anything that has
gone before, but it also features a
radical Eco Drive system, using a
lithium-ion battery pack for both
drive and crane functions, with a
smaller diesel engine to help power
the electric motor and recharge the
batteries. AC mains
power is also
possible.
The Spierings
City Boy
The single cab sits at the front of
the crane for road travel and once
moved into the crane position can
also ascend the tower in order to
provide a classic tower crane view
of the job site. The 400kW (540hp)
compact electric motor directly
drives the front axles. A frequency
controller converts accelerator
pedal operation into a continuously
variable acceleration of the chassis
from 0 to 80 km/h. The same
electric motor serves as a
regenerative electric brake when
slowing, generating power that is
passed back into the batteries.
The diesel engine, when used, runs
at a constant speed, powering a
generator that converts the energy
to electrical power to power the
drive motors or keep the batteries
topped up. An auxiliary hydraulic
motor powers the rear axle to
provide extra traction when
required on site. The crane can
also travel with the cab in the crane
position. The three section tower
fully extends before the jib is
unfolded to provide 30
metres height under
the horizontal jib.
The jib also luffs
to 45 degrees to
provide a
maximum tip
height of
55 metres. Maximum
capacity at full height and
maximum radius of 36 metres is
2,000 kg.

In addition to an
ultra heavy-duty
luffing jib tower
crane - the WT 2405L e.tronic -
Wilbert is unveiling a completely
new and more mainstream 170
tonne/metre luffing jib crane. The
WT 175L e.tronic has up to 36
metres jib and maximum single
item assembly weight of just 1.5
tonnes. The crane also features a
short four metre counter jib
making it ideal for city sites.
Raimondi MRT294
Raimondi Cranes will show its 16
tonne capacity topless MRT294
tower crane with 76 metre jib. The
crane includes a new deluxe cab
with seven inch touch screen for
better control and incorporates an
anti-collision system.

Bluelift's
new
C22/11
Platform Basket 22.10
We now have a picture of Platform
Basket's new 22 mete 22:10 with
up to 10 metres outreach and
variable outrigger positioning.
Bluelift C22/11
The 22 metre, Bluelift C22/11
weighs just 3,000kg and offers a
maximum outreach of 11 metres
with a 200 kg capacity. The 110
degree articulating jib and 160
degree platform rotation add to its
versatility. Closed dimensions are
900 mm wide, 1.98 metres high
and 5.2 metres long, but this can
be reduced to 4.5 metres with the
basket removed.
Standard features include
extendable tracks, radio remote
controls and three position outrigger
settings. The unit is Honda powered
with AC power motor for indoor use.
