The J D Neuhaus Profi TI range of air operated hoists incorporate many years of design and development, and have successfully proved their versatility and reliability following installations within a wide range of light, medium and heavy duty industrial workplaces. The major aspect of these hoists is that they have been engineered for extremes and can be safely operated even where hazardous working environments exist. Their compressed air supply, utilized for both power and control functions, does not initiate sparks, so providing an unbeatable advantage when hoists are operating in potentially explosive atmospheres. Even greater safety can be achieved by the prevention of sparks generated by static discharges or metal to metal friction contacts.
Standard versions of JDN hoists and crane systems (which utilize 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 galvanization 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 an impressive EX II 2 GD IIC T4 rating.
