dust-laden atmospheric conditions

To withstand tough conditions such as those found in foundries, JD Neuhaus’ air-operated hoists have been designed to provide safe and reliable load handling facilities, with 100 per cent duty ratings and minimum downtimes to maintain maximum production efficiency, no matter how difficult the working conditions. The absence of any electrical or electronic equipment, combined with highly robust air-vane motors, ensures that the JDN range of hoists are suitable for operation even in potentially explosive atmospheres.

Workplace safety being paramount, the hoists also provide a high degree of lift, lower and load positioning control to ensure full compliance with prevailing working practice regulations. With individual castings varying in their size and weight from under 1kg to several tonnes, JDN hoists are currently being successfully utilised in all areas of foundry operations with varying individual hoists providing load-handling requirements from 125 kg up to 25 tonnes or more.

The Mini series of JDN hoists can be supplied for load capacities of 125, 250, 500 and 980 kg. These compact, lightweight hoists can be supplied with trolleys for overhead rail mounting to accommodate load-traversing operations, utilising manual, reel chain or motorised trolley operation. A Mini Manipulator version can also be provided where single-handed load-handling and positioning can be safely undertaken.

For heavier handling requirements the rugged JDN Profi TI product range has been widely utilised for this market. These hoists are suitable for operation in the toughest industrial situations, providing individual lift requirements from 250 kg up to a full 100 tonnes if required. Where working conditions involve a restricted working height, then low headroom trolley monorail-mounted hoists have been supplied including ultra-low headroom variations where there are serious reservations on the working space available. Big-bag handling equipment, with single or twin load hooks for use with standard or more complex cruciform lifting beam designs, can also be supplied.

For longer loads, twin monorail mounted hoists can be used in tandem and connected with tie bars, or for longer loads twin hoists mounted on overhead rails can be supplied. All hoists are provided with rugged pendant controllers for all the lift, lower and load traverse movements, including precise load positioning, with a built-in emergency air shut-off valve also incorporated.

All the JDN products are insensitive to humidity, dust and temperatures within a range of -20°C to +70°C (mini +50°C). They operate on a compressed air supply of 6 bar with a low maintenance instant starting vane motor. A fail-safe disc brake holds loads in the event of air supply failure, with anti-climb and anti-drop devices incorporated as well as overload protection where specified. The products, except the Mini series (Ex II 3 GD IIA T4) have explosion-protection classifications of Ex II 2 GD IIA T4 / II 3 GD IIB T4 and Ex II 2 GD IIB T4 or II 2 GD IIC T4 with increased spark protection also provided where required.
