Hoists handling tough tasks

Carrying capacities from 250kg to 100t 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.

Safety features, such as 100% duty rating and explosion protection are important when working in hazardous areas. Compressed air does not generate sparks, while overload protection is available and is often provided as standard. The chain and hook are manufactured from high-quality tempered steels with a breaking strength some five times the nominal load. In line with customer requirements, various control systems are available, including remote controls, while for traversing loads, different trolley designs can be specified.

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

Profi air hoists are insensitive to humid and/or aggressive food production environments, delivering careful, yet reliable lifting and lowering. Here, Profi hoists take advantage of trolley wheels, chain and hooks made of stainless steel.
