Electrical cubicles Powerful hoist and travel motors also form with explosion proof cranes the heart of all electric chain and electric wire rope hoists. These must often prove their precise function in daily work for decades. Crane and trolley control panels that house the electrical control and regulation components are robust according to the area of application and are designed in the protection class “Pressure resistant encapsulation (d)“, “Increased safety (e)“ or “Protection by housing (tD)“. In explosive atmospheres, the protection of the motors for Zone 1 and Zone 21 is combined...

Rope guide Minimum hook travel Best approach dimensions Perfect utilisation of space and almost vertical lifting guarantee so that work is carried out precisely and safely We have increased the size of the drum, making everything else smaller. The main feature of our NOVA electric wire rope hoist is the extremely large diameter of the rope drum, which provides first-class protection of the rope, but there are also other features which guarantee safe and very cost-effective use. NOVA does away with load swinging and lateral hook movement, for example. NOVA lifts the load with virtually no...

Polipastos NOVAex Potential equalisation using earthing strap Potential equalisation at EX crane systems The installation of electrical systems in potentially explosive areas basically requires a variety of prevention measures. An indispensable protective precaution here is the potential equalisation of all live components. All components of the crane that can be live in the case of failure are connected together and then finally to the protective conductor. The need for this measure has also not remained unnoticed by the CraneKit and relevant components supplement and complete the...
