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. The JDN range covers both single and double girder overhead travelling cranes, together with slewing jib cranes and underslung cranes incorporating purpose designed low headroom hoist trolley designs. Cranes with individual hoists having load capacities up to 100 tonnes can be supplied, as well as multiple hoist crane products operating with single or twin parallel beams, while also providing individual or synchronised hoist control systems.
