Wherever tough or hazardous operating conditions place excessive demands on lifting operations, Profi series air hoists from J D Neuhaus (JDN) rise to the challenge. The JDN Profi range is now deployed in applications that range from chemical (including pharmaceutical, paints and varnish), foundries, and food and beverage, to list but a few. In such industries, the inherent design attributes of Profi hoists are proven that they can perform safe, high-performance and cost-effective lifting and lowering operations.
Profi air hoists are known for their robust design, a characteristic that makes them suitable for tough industrial applications, even in continuous working processes. Safety features, such as 100 per cent duty rating and explosion protection are an important advantage when working in hazardous areas. In line with customer requirements, various control systems are available, including remote controls, while for traversing loads, different trolley designs can be specified.
Put simply, Profi hoists excel in places where safety is paramount. After all, unlike electricity, compressed air does not generate sparks, while overload protection is available and is often provided as standard. What’s more, the chain and hook are manufactured from high-quality tempered steels with a breaking strength some five times the nominal load.
Carrying capacities from 250 kg to 100 tonne can be accommodated by Profi series air hoists, with 4 or 6 bar pressure compressed air. As standard, sensitive, infinitely variable speed control allows the precise positioning of loads, a function that is supported by frequent switching and extended duty cycles. Simple operation, sound absorption and suitability for lube-free operation are among further benefits of these low-headroom, lightweight hoists.
Low maintenance is also a primary attribute of the Profi series, which is insensitive to dust, humidity and temperature (from -20°C up to +70°C). In addition, the chain sprocket in the mid-section runs in dustproof, maintenance-free ball bearings, while the planetary gear, which features teeth made from tempered or hardened high-grade steel, is lubricated with long-life grease.
