Explosion-resistant JDN hoists

All J D Neuhaus products, which include both compressed air and hydraulically operated hoists and cranes, are explosion protected as standard.

This is said to ensure that they are safe for continuous and long-term operation in potentially explosive chemical atmospheres as well as the more insidiously dangerous conditions where high levels of airborne dusts exist. This can include combustible dusts, high concentrations of airborne dusts, or wherever a dust cloud is confined with an oxidant present (ie typically atmospheric oxygen) and particularly where there is an ignition source.

The Profi TI air operated hoist range is the workhorse of the industrial and commercial world, and the operating air supply can be set at 4 or 6 bar pressure, with a standard load lift height of three metres being provided throughout. Other optional lift height requirements can also be specified and accommodated as required.

The Profi TI range includes 19 models providing lift capacities from 250 kilogrammes up to 100 tonnes. Standard versions of JDN hoists and crane systems (which use Profi TI hoists for lift operations) have the explosion protection / classifications and markings EX II 2 GD IIA T4 / II 3 GD IIB T4.

Increased spark protection can be achieved, which involves copper galvanisation plating of the hoist bottom block and load hooks, together with fitting brass safety catches to achieve a rating of EX II 2 GD IIB T4.

With even further increased spark protection for explosion group IIC, the hoist horizontal movement trolleys incorporate running wheels and travel gearing which are manufactured in bronze for a EX II 2 GD IIC T4 rating.

All Profi TI hoists incorporate a top suspension hook, with optional overhead trolleys also available to accommodate lateral movement of suspended loads.

Meanwhile, the JDN Mini hoist range is available for light to medium lifting requirements. These cover four models for individual lift capacities of 125/250/500 and 980kg, with manipulator variations available for single handed operation during lift/lower/traverse and even final load positioning operations.

Hydraulically operated versions of the JDN Profi range can also be made available, together with hoists specifically designated for operation within unique working conditions. These include hoists available with compressed air or hydraulic operation, which are suitable for underwater work.

Overhead monorail air hoists having air or hydraulic drives can also be supplied with 11 models in the range covering lift capacities from 10 to 100 tonnes. Further ultra-low headroom versions are also available for lifting operation up to 100 tonnes, including specialised products available for BOP handling up to 200 tonnes. Hoists for specialised lifting in cryogenic conditions down to temperatures of -45 deg C are also now available.
