JD Neuhaus focuses on safety with its latest product.
hoists. With this feature JDN complies with the leading standards like NORSOK, specifying an emergency device for the safe lowering of loads in the event of a cut in the main power supply. Te new device supplements an existing fail-safe disc brake, which is activated in the immediate event of a mains power failure, ensuring that suspended loads are held safely and securely at their above-floor level until mains power is again made available. JDN monorail hoists with liſt capacities from 25 to
60tonnes can now be equipped with the latest safety development. This comprises an additional separate pressurised air reservoir tank (maintained at a mains air pressure of normally 6bar), with a purpose built hand controller incorporating two additional push buttons. Te controller provides positive two-handed lowering control, while eliminating the potential for unintended load movement. One button switches between normal and emergency lowering operations. Te second button activates the integrated safety brake enabling the safe, controlled lowering of a deadweight load. Te air reservoir, which is protected by a check valve, is topped-up during normal hoist operations, and contains sufficient air supply to complete a controlled lowering of suspended load in the event of a loss of mains air pressure.

Ancillary equipment Cargotec gets
onboard with MOL MOL’s latest generation of ‘eco-friendly’ efficient PCTC’s will have MacGregor roro access outfits from Cargotec installed onboard, making them the world’s first car carriers to have all of their roro equipment electrically-driven. Cargotec’s growing electric-drive roro reference
portfolio now includes the first vessel to have all-electrically-driven roro access equipment entering service. Te 4000 unit pure car truck carrier (PCTC), Iris Ace, is owned and operated by Japanese company, Mitsui O.S.K. Lines Ltd (MOL) and features an electrically- driven MacGregor stern quarter ramp/door, side ramps and two movable ramps from Cargotec.

MacGregor electrically-driven stern quarter ramp on Cattleya Ace NB 3643; Shin-Kurushima Toyohashi shipyard.
Iris Ace was delivered from Japanese shipbuilder,
Shin-Kurushima Toyohashi Shipbuilding Co Ltd earlier in 2011 and was followed into operation by a pair of 6400unit PCCs, Cattleya Ace and Carnation Ace, from the same builder. Each of these two ships features an electrically-driven MacGregor stern quarter ramp/door, a centre ramp/door and six movable ramps. All equipment is operated by electric winches and actuators, eliminating the use of hydraulic oil in the operating system. Last year Cargotec and the Shin-Kurushima Dockyard
group also signed further agreements for four pure car carriers (PCCs) to be fitted with fully electrically-driven roro access equipment
