Doosan Portable Power at Intermat 2015
The Doosan Portable Power display at the
Intermat 2015 Exhibition will include a
number of important new products being
launched at the show. They include rede-
signed and Stage IIIA compliant G40-IIIA
and G60-IIIA generators, alongside several
new portable compressors including the
Stage IIIA compliant 7/53, Stage IV compli-
ant 12/154 and 12/254 and 7/125-10/110
Stage IIIB Dual Mode models.
Providing 40 kVA and 60 kVA prime pow-
er, respectively, the G40-IIIA and G60-II-
IA models are part of the new platform of
generators from Doosan and share a com-
mon design with the G80-IIIA to G200-IIIA
models launched over the last two years.
The Yanmar-powered G40-IIIA and John
Deere-powered G60-IIIA generators will
both be available with electronic speed
regulation (optional on the G60-IIIA model)
providing, in addition to stability and better
load take-over capabilities, a flexible dual
frequency 50/60Hz working mode (optional
for both models).
Like all Doosan generators, the new
G40-IIIA and G60-IIIA models offer robust-
ness and reliability, high performance and a
wide choice of features to meet the needs
of every rental and temporary power appli-
cation. The output performance stability of
the generators is ensured by an optimised
powertrain featuring a combination of the
new Stage IIIA engines and Leroy Somer
AREP alternators.
The new 7/53 portable compressor is a
36 kW Stage IIIA compliant replacement for
the 7/51 model and has been redesigned
to allow Doosan to keep this model in the
Stage IIIA category, avoiding the need to
transition to meet Stage IIIB regulations.
The new features on the 7/53 portable
compressor include forklift slots and a new
bunded base option.
The 7/53 compressor has an intuitive,
simple key-start sequence, ideal for rental
companies because of the reduced risk of
machine abuse by untrained operators. The
user-friendly control panel offers an open
layout of instruments and warning indica-
tors. A folding lift bail reduces the risk of
theft by keeping the lifting eye within the
compressor enclosure. A built-in toolbox
compartment offers ample storage space.
New Bobcat Telescopic
Handlers at Intermat 2015
Linden Comansa launches in February
2015 her new 21LC335 flat-top tower
crane, which is part of the LC2100 se-
ries. This new tower crane is the result of
the review of the 21LC290, a model that
Linden Comansa produced with success
since 2002, and which will be replaced by
the 21LC335. Both cranes feature similar
characteristics in terms of range (up to
74 m - 242.8 ft), maximum freestanding
height (64.5 m - 212.9 ft) and versions
depending on the maximum load capacity
(12 and 18 t - 26,450 and 39,680 lb).
The changes made as a result of this
review have led to an important increase
of load capacity with maximum reach-
es under 70 m (229.7 ft). For example,
the 21LC290 18t with a 50 m jib (164
ft) can load 5,300 kg (11,680 lb) at the
end of the jib, while the new 21LC335
18t with same jib length loads up to
6,600 kg (14,550 lb), almost 25% more.
With this same 50 m jib configuration,
the 21LC290 moved the maximum load of
18 tons (39,680 lb) up to 16.3 m (53.5 ft),
while the 21LC335 moves the maximum
load up to 19.6 m (64.3 ft), 20% more.
The tower sections of the 21LC335 are
the S25, the same as the 21LC290, and
the jib and counterjib sections are also the
same as its predecessor. There have been
modifications only on the cat head and the
upper turntable, allowing customers who
would like to convert their 21LC290 into
a 21LC335 to do it by replacing these two
elements and modifying the configuration
of the counterweights. These changes
have also allowed to simplify and shorten
the assembly sequence of the 21LC335 in
comparison to the 21LC290.
The 21LC335 crane comes standard with
a Effi-Plus high speed hoist mechanism that
reaches speeds of up to 150 m (492 ft) per
minute, although there are other optional
engines that can reach 228 m (748 ft) per
minute. Like the rest of Linden Comansa’s
flat-top cranes, this new model includes the
PowerLift system, that allows to improve the
load diagram up to 10% with reduced speeds.
