SHOW GUIDE
CONEXPO
TOWER CRANES
LIEBHERR, GOLD LOT 2155
, will show two
tower cranes at its huge stand, including
a 542 HC-L 18/36 Litronic with a large
luffing jib and a capacity of 79,366
pounds, or 36 metric tons. For situations
where several cranes need to be set close
together, the luffing gear can be optimized
according to lifting capacity to allow
shorter adjusting times. Infinitely variable
frequency drives are standard on the 542
HC-L. The entry-level model 542 HC-L
18/36 Litronic includes a 110 kW FC
hoist unit, 110 kW FC luffing gear with
secondary brake, plus two 11 kW FC
slewing gear units.
From its flat-top tower crane range
Liebherr is showing its 380 EC-B 16
Litronic. Maximum radius for the 16
metric ton crane is 246 feet and it can lift
7,496 pounds at the end of the jib.
Easy transport was a primary
consideration in the design of the crane,
which has a distinctive appearance and
four-chord counter jib. The compact
superstructure with full jib can be loaded
onto only five trucks, according to
Liebherr. In addition, it is designed so
that the dimensions of each individual
part meet the requirements of container
transport for easy loading onto ships.
The whole EC-B head, including the IC
slewing ring support and full jib, will
fit inside a series of 40-foot shipping
containers.
Spanish tower crane company
LINDEN
COMANSA, GOLD LOT 2181
, and its
subsidiary Linden Comansa America,
will show several new developments in
its tower crane line. Product highlights
include the new LCL 165 luffer, which
completes the five model LCL series. It
is available in 17,640- and 26,450-pound
capacity versions. Also completing a
range is the new 21LC 660 flat top tower
crane in the LC2100 series. Four versions
are available, with 18, 24, 36 and 48
metric ton capacities. This model has the
manufacturer’s longest jib at 84 meters.
Largest in the range is the LC3000 series.
A pair of models, the 30LC1100 and
the 30LC1450, are available in in three
versions, with capacities of 32, 48 and 64
metric tons. Two steps down the product
range is the LC1600 series of three flat-
top tower cranes. The 16LC185 comes in
three versions, with 8, 10 and 12 metric
ton capacities. The 16LCL220 and the
16LC260 are available in 10 and 12 metric
ton versions.
New from Linden Comansa is its
PowerLift control system that allows an
improvement of the load chart by up to 10
percent at reduced speed. It is a standard
feature on all the company’s flat-top
models. On show will be the turntable,
cabin, hoisting machinery and trolley/
hook assembly of the 21LC 660, which
will be powered and can be operated by
prospective customers.
The
POTAIN, GOLD LOT 2137
, tower crane
brand will be represented by a new luffing
jib tower crane and what Manitowoc
claims as the world’s largest self-erecting
crane. The MR 418 luffer is the first
unit in a range under development with
more units coming later in the year. All
will have frequency converter drives.
Application includes power station or
super high-rise (656 feet and taller)
building construction.
The MR 418 lifts 24 metric tons with a
maximum jib length of 60 meters. It can
be fitted with the 201 kW (270 hp) 270
LVF 120 hoist winch (designated 320 LVF
120 in North America) with up to 830
meters of rope. For greater productivity
the maximum line speed is 254 meters per
minute. Mounting the luffing mechanism
and the hoist inside the counter jib
reduces the amount of space the crane
needs on site and simplifies assembly,
according to Potain.
Alexandre Chanteclair, Potain product
manager for top slewing tower cranes,
The Linden
Comansa 21LC
660 flat top tower
crane turntable,
cabin and hoisting
machinery and
trolley/hood
assembly will
be available for
demonstration.
The Potain MR 418
is a compact crane
that is quick to
assemble and offers
fast lifting speeds.
The two tower cranes on display at the
Liebherr stand include the 542 HC-L 18/36
Litronic and the 380 EC-B 16 Litronic.
