displacement piles andTurbojet piles.
The SR-45 and SR-75 feature an integrated re-design of
the mast, rotary, kelly and parallelogram. This helps with the
forward weight balance of the machine, providing enhanced
stability, greater crowd and extraction force, and increaseddepth
capability.
The SR-75 also offers a low-headroommast for that type of
drilling, while the SR-45 has bottom feed system technology
for drilling in areas that are seismically active or have unstable
ground conditions.
Alsonew to the Soilmec line-up, the SM-17 is amultipurpose
drilling rig suitable for micro drilling and anchoring.The SM-
17 isfittedwith adouble rotarymechanism,which allows casing
and the drill string to be advanced independently.

German manufacturer Liebherr has seen its new LB 44-510
rotary drilling rig go into operation on the construction of a
particle accelerator inDarmstadt, Germany.
Launched at the Bauma 2013 exhibiton, the LB 44-510 is
the latest development in Liebherr’s range of deep foundation
products. With a torque of 510 kNm, Liebherr claims it is
the largest and most powerful rotary drilling rig currently in
operation inGermany.
In kelly drilling applications, it is configured for drilling
diameters of up to 3m and depths of up to 92m.The drilling
rig weighs some 170 tonnes and is powered by a V8 diesel
engine offering 505 kW (677 hp) and complying with the IIIB
andTier 4 Interim emissions standards.
Two LB 44-510 rotary drilling rigs are being used on the
construction of the Facility for Antiproton and Ion Research
(FAIR) international particle accelerator. The drilling rigs are
there to stabilise the subsurface with cast-in-place drilled piles.
The jobwill see 1400piles,measuring between40m and62m,
set in the ground.
Meanwhile, Liebherr’s deep foundation equipment is being
put to work inCanada, with an LRH 100 piling rig laying the
foundation for a new bridge in the province ofQuebec.
The piling rig was equipped with the large H 85/6 hydraulic
hammer to install 120 piles with a diameter of 450 mm and
total lengths of up to 36m.
The LRH 100 is equipped with a powerful and emission-
optimized270kWLiebherrdiesel engineandcanbe transported
in one piece with the hammermounted. Compact in design, as
the smallestmodel in the Liebherr range of pure piling rigs, and
with a 3m transport width, the unit can be transported quickly
and cost-effectively.
