What’s New at Bauma 2016 Preview - 1
New 21LC450 20t and 25t
When assessing the modifications to be implemented
in the 21LC400 18 t model, the R&D team of Linden
Comansa saw the opportunity to greatly improve this
The result is a new model, the 21LC450 crane with
20 and 25-te versions, versus the previous 12 and
18-tonne 21LC400 crane.
To achieve such an obvious improvement, not only
have the hoist cable and trolley/hook assembly been
modified, but the slewing part of the 21LC400 has also
been replaced (turntable, slewing ring and cat-head)
with a newly designed unit, which is common to the
slewing part of the 21LC550 25 t.
This means, not only is the crane strengthened, but
modularity and interchangeability of elements between
the new 21LC550 25t and 21LC450 are also facilitated.
In addition, most jib, counter-jib and tower sections
of the 21LC450 are identical to those of the 21LC400,
which allows companies that own both models to swap
sections as needed.
Increased Load Capacity
When compared with the 21LC400 18t, the 21LC450
20 t has a maximum load capacity of 2 t more than its
predecessor, also with an improved load chart.
For example, with its 50 m range, the 21LC450 can
load up to 10 t on the tip, while the maximum load ca-
pacity of the 21LC400 was less than 9 t.
The maximum load capacity is increased in the
21LC450 25 t by 7 t, when compared with the 21LC400.
This crane has a tip load capacity of 2,600 kg (2,860 kg
with PowerLift, which comes as standard) and can load
up to 25 t, up to a reach of 20.6 m and with a 40 m
The 21LC550 with a 12 t maximum load capacity has
also been retired from the catalogue, as currently Linden
Comansa offers better alternatives to the market.

Atlas Copco New FlexiROC
T20 R (Mk II)Atlas Copco Surface and Exploration Drilling Division
has introduced a major upgrade to the FlexiROC T20R
that was introduced three years ago. Because of the
success of the former model, the major upgrade will
probably be on the Atlas Copco stand at Bauma 2016.
The company says that the Mark II model has been
redesigned from the ground up to introduce features
requested by customers.
As the Product Manager Marcus Leü says:
"In response to requests from our customers
around the world, upgrades have now been
made making the new FlexiROC T20 R the best
drill rig in its class of compact, radio remote
controlled drill rigs."
A great deal of effort has been put in to make good
use of the commonality between parts. This results in
the use of well proven technology and quality compo-
nents. For the customer this translates to a reliable drill
rig with maximized uptime.
A completely new rig control system that consists of
electrical and hydraulic components as well as the Radio
Remote Control (RRC) has been installed.
By using well proven technology from drill rigs such
as FlexiROC T25 R & T30 R, functionality and quality are
Other examples of upgrades are; new cylinder feed
(BMH 2000) in three different lengths, new reinforced
drill steel support, new hose routing with three bulk-
heads, new front facing feed holder and better service
More Power for Increased
The FlexiROC T20 R (MkII) has now been equipped with
the COP 1435 rock drill. It has almost 30% higher impact
energy and 30% higher rotation torque than the previous
With an impact power of 14 kW together with smooth
cylinder feed action, the drilling performance has in-
creased by up to 40%.
The Drill rig is for hole diameters of 38 - 64 mm in
trenching or foundation drilling and underground service
operations. It is powered by am 82 kW Cummins engine
A boom reach of 3,500 mm through a 90° radius
allows for more holes to be frilled with fewer set-ups.
The rig can perform 360° drilling in all directions giving
it exceptional versatility.
