Australian-based Northern Stevedor-
ing Services (NSS) placed an order for a
Liebherr mobile harbor crane, type LHM
420, to operate on Berth 3 and 4 in the
Port of Townsville, Queensland. The op-
erations of the stevedoring company span
all of regional Queensland’s major port
facilities, providing the full range of ste-
vedoring and logistics solutions. The new
crane is the third LHM crane for NSS,
which has been operating an LHM 550
and an LHM 1300.
The crane comes with double support-
ing pads and software to assist in meet-
ing the quay limitations, along with Lieb-
herr’s Cycoptronic anti-sway system and
a twinlift spreader. The LHM 420 is also
fi tted to operate with the Rotabox system
for dust-free high-value mineral handling.

For Damen Shipyards, Bosch Rexroth
developed and engineered both the hy-
draulic and electrical systems for the
winches of a new tugboat.
The Damen ASD Tug 3212 is a newly
designed tugboat for assistance activities
at offshore LNG and oil terminals and
open sea loading stations for the mining
industry. The tug has 85 t Bollard Pull, a
speed of 14 knots and two deck-mounted
winches: one at the bow and one at the
stern.
The winches are directly driven by
the second-largest motor from the Häg-
glunds CB series. This compact and low-
speed hydraulic motor features a low
mass moment of inertia, high torque and
minimal servicing needs.
The complete project comprised the
pump sets, manifold blocks, motors,
system controller, control cabinets and
operator panels. Because Bosch Rexroth
developed all the hydraulic and electri-
cal systems needed – where they used
proven components and technologies –
the fi nal solutions have a very compact
design.
