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. www.liebherr.com

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. www.boschrexroth.com
