Quality products, combining reliability,
performance and longevity, for operation
in hazardous or arduous conditions

J D Neuhaus, one of Europe's foremost materials handling and lifting specialists, has established a reputation for quality products, combining reliability, performance and longevity, for operation in hazardous or arduous conditions.
 
The company's latest products include many of which have been developed to cover specialised applications within particular industries. These include the EH 25 monorail hoist which is designed to fulfil all requirements for the safe and effective handling of BOP products whether for offshore rigs, sea going vessels or land based operations. A 25 tonne lift capacity is combined with air or hydraulic operated lift and travel movements, together with optional remote electrical or radio controls. For shipbuilding or general shipyard applications the new JDN Profi 25 TI hoist provides both horizontal and oblique lifting and pulling with sensitive positioning control and rugged reliability. The EH and Profi hoists both benefit from recent design advantages in performance, low component count and energy savings with models also available with 37 and 50 tonnes lift capacities.
 
To complement these marine proven products, the company offer its Profi 6 TI air operated hoist developed for subsea operation. Other 25 tonne capacity hoists have already been successfully deployed in underwater repair operations on a large tanker vessel while still afloat.
 
Their Profi 2 TI hoist can be equipped with a low headroom trolley for overhead rail operation. This product, with a 2 tonne lift, is ideal for many industrial applications such as foundries and chemical, cement and pharmaceuticals production. Hoists with up to 100 tonnes lift capacity can be supplied from their Profi range, equipped with manual, reel chain or motorised trolleys.

For food and other light industry applications, the Mini 250 hoist will be demonstrated with a 250kg capacity. This is a handy, flexible and universally deployable air operated hoist, that can be complemented with 125, 500 and 980kg capacity versions.
 
A Profi 3 TI hoist of 3.2 tonne capacity and suitable for cryogenic operation down to -20°C will also be shown, ideal for cold store operation. These products can be either air or hydraulically operated. For operation at temperatures from -20° to -45°C, hydraulic hoists can be supplied fitted with a pre-heating device for the drives, with cryogenic hydraulic oil used for the control, traverse and lifting operations. An adapted EH 20 hydraulic monorail hoist has also been successfully tested for operation at these extreme arctic conditions.

Hoists designed for the oil and gas
industry used in FPSO mooring system

The J D Neuhaus company have a long established reputation for the design and manufacture of materials handling products. They also supply purpose designed equipment for specialised applications such as the oil and gas industry where safety and reliability are primary requisites.

For this purpose they can supply hoists, with a lift capacity range from 0.25Kg up to 100 tonnes, to API7K certification. These are high durability products rated explosion proof/spark resistant and powered by compressed air or hydraulics with corrosion resistant options also available. Customised lifting and control systems can be accommodated with load test certifications available through DNV, ABS, Lloyds and others. Typical land based or offshore equipment loads include BOP handling, FPSO (Floating Production, Storage and Offloading) vessel mooring/tensioning together with a wide range of general materials handling requirements on jack-up rigs, semi-submersibles, drill ships etc. Specialised hoist applications have also been developed for operation in low temperature 'cryogenic' conditions, together with hoists for subsea operation down to levels of 70 metres.

The FPSO vessel is used as a temporary storage unit for oil or gas from offshore production platforms before it is subsequently transported by a pipeline or oil tanker to the store depot. An integral piece of equipment on FPSO's are the hoists used to manoeuvre equipment both on and around the vessel. Subject to heavy loads and harsh environments, the JDN hoists provide an essential 'strongest link' in these material handling operations.

Bardex Corporation, headquartered in Goleta, California, was contracted to design and build the mooring system for an FPSO ordered from Elf Petroleum Nigeria, Ltd. (EPNL), a Nigerian subsidiary of French Oil company Total S.A., and contracted through Hyundai Heavy Industries (HHI). A number of overhead cranes were evaluated before Bardex concluded that JDN's hydraulic overhead crane was the best option.

Instead of procuring 16 separate chain jack tensioning systems (four per corner of the FPSO and each rated at 18 tonnes), it was determined that one unit per corner could be used and a system of four overhead cranes used to move one chain jack tensioning system for use in all four corners of the FPSO. Additionally, the specially designed mooring system included sixteen fairlead stoppers each weighing in at almost 25 tonnes.

A system like this had never been built before, and JDN was the only crane builder in the world capable of supplying it to specification and on time. It comprised a hydraulically powered overhead crane with a hoist lift capacity of 18 tonnes, designed to withstand daily ocean environmental conditions with a high atmospheric moisture content.

Established in 1745, J D Neuhaus is the acknowledged premier manufacturer of air-powered handling equipment in the world. Their products operate safely and reliably in some of the most demanding and difficult environments in the automotive, oil & gas, and mining industries, while offering unmatched quality and superior service.

Inaugural lift for 100 tonne JDN Profi TI Hoist at gas terminal

The inaugural lift for a Profi TI 100 tonne air operated hoist unit has been successfully accomplished at the St Fergus gas terminal located near Peterhead on the North East coast of Scotland.

This powerful hoist is one of the latest pieces of heavy duty lifting equipment recently added to the J D Neuhaus hire range, and is believed to be one of the largest air driven hoists available for hire in Europe. It complements an extensive range of fully Ex rated JDN hoists, with lift capacities from 250kg up to 100 tonnes, now available from the rapidly expanding hire fleet at the recently opened J D Neuhaus service centre in Aberdeen.

The important operation of lifting a furnace from a dedicated low-loader unit within the live area of the St Fergus gas terminal was undertaken by Enermech Limited, a specialist lifting company who have headquarters in Aberdeen. The St Fergus terminal processes gas from over 20 North Sea fields and is responsible for transporting offshore gas to shore, receiving the gas onshore, processing the gas to National Grid specification, delivering the gas to shippers and ensuring a balance between supply and demand.

The lift site within the terminal was in close proximity to gas pipes which carry up to 20% of the daily gas supplies required for the UK. Mobile cranes were not permitted in the live area, so a pre-manufactured lifting frame was supplied to support both the hoist and the load. After suitable positioning within the plant, the lift, transfer and positioning of the furnace was safely and successfully carried out, providing a cost effective solution to the task in hand.

Arthur Hedley, Managing Director at J D Neuhaus UK commented: "the Profi 100 TI hoist is proving to be a very desirable addition to our rental fleet which is now being utilised on a global basis and has also recently been strengthened by the addition of a further forty units, including four 50 tonne plus eight 25 tonne hoist units."

The Profi TI air operated hoists available in the hire fleet are all fitted with top suspension hooks with optional manual, reel chain and motorised trolleys available for conversion to overhead rail mountings to accommodate lateral load transfer movements. Hoists with lift capacities from 250kg up to 100 tonnes can be supplied, all Ex rated for hazardous area operation. They incorporate sensitive, infinitely variable speed controls for the precise positioning of loads and are insensitive to dust and humidity in operating temperatures from -20°C up to +70°C.
