J D Neuhaus broadens hazardous environments reach10 December 2014
J D Neuhaus has outlined its crane system offering for customers wanting products with Atex classifications EX II 2 GD IIA T4 / EX II 3 GD IIB T4.
The company also offers systems with increased spark protection also available for explosion level II C.
Standard applications for products in this space are generally found in mining, tunneling, foundries and cement plants, as well as toxic and hazardous locations.
All load lift, lower and traverse operations operate off a pneumatic air-line pressure of 85psi (6 bar), with optional hydraulic operating systems also available. This eliminates the potential hazards and dangers associated with electrically powered equipment when operating within areas of high dust or humidity.
According to the manufacturer, the JDN range covers both single and double girder overhead travelling cranes, as well as slewing jib cranes and underslung cranes that incorporate purpose designed low headroom hoist trolley designs.
The firm can supply cranes with individual hoists with load capacities up to 100 metric tonnes, as well as multiple hoist crane products operating with single or twin parallel beams, while also providing individual or synchronized hoist control systems.
''For offshore lifting operations, including on sea going vessels, cranes can be supplied with rack and pinion drive systems for safe operation even in bad weather conditions. Super-silent operation is combined with sensitive controls including an automatic safety function for load-lowering in the event of power supply failure,'' the company said.
It added: "Special purpose, fully customized cranes can also be supplied to customer specifications. For companies looking for self-build projects, JDN also supplies crane kits. These are designed for the manufacture of overhead travelling cranes and underslung cranes.
"They feature the use of a single span beam providing the hoist support and running platform. This includes both overhead travelling and underslung mountings which are supplied with crane drive motors and space saving energy chain systems for the power supplies for both long and cross travel movements."
the corrosive atmospheres of the galvanic industry have also been supplied.
According to the manufacturer, its cranes arrive insensitive to dust, humidity and aggressive atmospheres as standard, and operate within a temperature range of -20°C to +70°C.
