The crane systems manufactured by material handling specialists J D Neuhaus are designed for taxing operating conditions, and have a proven track record throughout worldwide installations. Industry applications include oil and gas exploration and processing locations, both on and offshore, where explosion-proof operating conditions are paramount. Utilising an impressive range of compliance standards ensures that the JDN equipment is also suitable for safe operation in a wide range of industrial and commercial activities, meeting the relevant safety standards where appropriate. Examples include, APi 7K, Ansi B30.16, ABs, dnv Approval Programs, norsok; tensile strength 2.5, dynamic factor 1.33; safety factor 5:1 acc to Ansi B30.16.

These JDN handling products are fully supported by a worldwide servicing operation providing product supply, installation, maintenance and service/repair services with traceability through the JDN unique parts marking system.

Typical standard crane systems currently available include: overhead cranes with single or double girder design; underhung cranes including low headroom design; jib cranes; cranes with in-line mechanically linked synchronised hoists; cranes with parallel operating hoists; crane capacities up to 100 tonnes; crane operation spans up to 36 metres. All products are suitable for both indoor or outdoor installations with optional power supplies for compressed air or hydraulics.

The J D Neuhaus cranes and hoists are resistant to dust, humidity and aggressive atmospheres as standard, operating within a temperature range of -20°C to +70°C. They provide 100% duty ratings with no downtime and only minimal maintenance requirements. Overload protection and fail-safe braking are incorporated with emergency-stop safety features. Special limit switch arrangements for end-travel, anti-collision and protected zone status can also be incorporated as required.

Both standard and custom built crane designs can be supplied with crane kits, to fully accommodate customers’ design and build requirements. Component kits complete with pneumatic or hydraulic drives can be supplied to crane manufacturers for overhead travelling cranes up to 10 tonnes capacity. The customer simply provides the main girder with JDN supplying all the necessary components for building a crane to their chosen design. Along with hoist and trolleys, JDN provide end carriages with drives, energy feed systems and appropriate safety accessories.

JDN crane systems have been utilised in many general engineering operations ranging from typical heavy duty operations like power plants, refineries, sawmills, foundries, shipyards to even explosives and pyrotechnics manufacture. The Ex classifications applicable to the JDN products according to EC Directive on Hazardous Locations 2014/34/EU are EX II 2 GD IIA T4 / II 3 GD IIB T4.
