Air hoists for safe lifting in tough operating environments

Wherever tough or hazardous operating conditions place excessive demands on lifting operations, Profi series air hoists from J D Neuhaus (JDN) are well suited. The JDN Profi range is now deployed in applications that range from chemical (including pharmaceutical, paints and varnish), foundries, and food and beverage.

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% 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.

Profi hoists excel in places where safety is paramount. 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 250kg to 100 tonnes can be accommodated by Profi series air hoists, with four or six 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 hoist.

Low maintenance is also a primary attribute of the Profi series, which is insensitive to dust, humidity and temperature (from -20 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.

In sectors such as chemical and pharmaceutical, Profi air hoists lift and transport raw and finished goods, as well as auxiliary equipment such as submersible pumps, big bags and mounting tubes. Explosion-proof operation is clearly paramount in such operating environments. Here, Profi hoists offer explosion protection as standard, providing sensitive lifting and lowering, complemented by insensitivity to fumes and other environmental influences.

For the paint sector, Profi hoists typically handle cylinders, rollers and coils. Here, both explosion-proof operation and low-headroom design make these advanced hoists a well suited tool for the job.

In foundries, Profi hoists are also proving their value. Foundry tasks include transporting and discharging ladles with liquid steel, lifting and turning moulds, handling cast parts on shaking grates, and cleaning castings. Users of Profi hoists in these tough operating conditions benefit from insensitivity to high temperatures and dust, as well as high lifting and lowering speeds, and 100% duty cycle.

The story of success is similar in the food industry, for tasks such as handling containers in jam or marmalade factories. In these applications, Profi air hoists are insensitive to humid and/or aggressive food production environments, delivering careful, yet reliable lifting and lowering, time after time. Here, Profi hoists take advantage of trolley wheels, chain and hooks made of stainless steel.

Ultimately, Profi air hoists from JDN are engineered for extremes by delivering safe, reliable, high-performance operation in a wide range of tough industry applications, while also providing low cost of ownership.
