Air Operated Hoists Provide Safe Solution ҵ،障Ґ机升提动气


Te 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. Te hoists have been engineered for extremes and can be safely operated in hazardous working envi- ronments. Teir compressed air supply, utilized for both power and control functions, does not initiate sparks, and greater safety can be achieved through 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 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 EX II 2 GD IIC T4 rating. Te Profi TI hoist range is the workhorse of the industrial


and commercial world, providing lift capacities from 250 kg up to a full 100 tons. Te 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 require- ments can also be specified and accommodated as required. All Profi TI hoists are equipped with a top suspension hook,


with optional overhead trolleys also available to accommodate lateral movement of suspended loads. Tree trolley options incorporate load traverse movements combined with precise load placements. One trolley is manually operated for hori- zontal movement of the suspended load. A second trolley has a manually operated reel chain mechanism for lateral load movements. Te third motorized trolley provides traverse as well as load raise and lower movements utilising compressed air power. All trolley systems can negotiate over-


head rail curvatures and be fitted with rack and pinion drives for safe load handling on offshore platforms and sea going vessels. Profi TI hoists are 100% duty rated with unlimited duty cycles, minimizing downtime. Teir compact design eliminates protruding control hoses or similar external parts suscep- tible to damage, emphasising the suitability of the Profi range for even horizontal pulling. Hydraulically operated versions of the


JDN Profi range can also be made available. ■
