All these JDN products are Ex rated to ensure the highest levels of safety for operating in potentially explosive or other dangerous atmospheres which can occur in many diverse industries. A specific mining application of JDN products include a Profi TI hoist with 37 tonne lifting capacity used for the safe and successful handling of an assembled pipeline string of some 1000 metres in length. This involved the connection of individual pipeline sections, each eight metres long, to create a completed string weighing 30 tonnes, which had to be positioned within a mining shaft. The compact and flexible hoist, offered excellent weight/load ratios, with the Profi 37 TI having an all-up weight of 880kg (with a standard 10 metre chain length) while providing an impressive 37.5 tonne lifting capacity. The company has been designing and manufacturing handling equipment for over two and a half centuries, and pioneered the use of compressed air for powering handling equipment in the early 1950s. The latter development ensured that their lifting and pulling equipment was suitable for use in hazardous areas and environments where there was a potential explosion risk.
