With 30 years experience in offshore materials handling, the J D Neuhaus company announce a new generation of purpose designed monorail air hoists. The new EH25 hoist in this range has a lift capacity of 25 tonnes and can be supplied with either air or hydraulic control of the lift and travel movements, as well as optional remote electrical or radio controls. The product fulfils all the requirements for safe and effective BOP handling, whether for vessel, offshore or land based operations. With an Ex rating for operation in explosive atmospheres, the hoist is also ideally suited for applications in other hazardous conditions typically as found in the chemical or cement manufacturing industries.
Standard features include optimised air flow guidance and reduced noise levels with up to 25% less air consumption due to a new energy saving valve. Adjustable beam width mounting and 3 metre lift is provided, together with an offshore corrosion protection package. Overload adjustment is from 90 to 125%, with a 5:1 hoist safety factor and 3.1 certification on load carrying parts. The new design utilises less components, with lube-free operation and a low maintenance level achieved from the new generation of brake motors. The product also complies with standards API 7K, ABS, ANSI B30, NORSOK and DNV approval programs. It is also subject to the JDN unique parts marking system for component traceability.
Optional features that can be provided include overload protection and a load monitoring system. Particularly suited for shipboard applications is a rack and pinion drive for horizontally travel movements, together with an articulated trolley for limited side pulling operations.
Hoist manufacture is subject to Quality Management System according to ISO 9001 and Environmental Management System according to ISO 14001 by the TUV Rheinland. A worldwide servicing operation can also be supplied if required.
