Our high-performance electric belt hoist was originally developed for clean rooms and for installation in clean room cranes. For production in clean rooms, minimising the negative effects of airborne particles is essential. The unbeatable advantages of the electric belt hoist used in such clean rooms and clean room cranes have led to their use for production in other sectors. Our reliable belt hoists stand out with the following characteristics:
- Use of maintenance- and lubricant-free load belts instead of cables or chains
- Extremely low natural vibration for high-precision positioning of loads to be lifted
- No polygon effect and no lateral hook travel when lifting or lowering
- High resistance to wear
- Smooth surfaces for easy cleaning
- Low-wear material combinations on friction surfaces (e.g. drive wheel treads) prevent formation of electrically conductive abrasion products
- Extremely low noise emissions
- Hooks made of stainless steel or with hard-chrome plating
Businesses that produce electronic components are one example of companies that use our clean room cranes because of the above benefits. Electronic components are extremely sensitive to magnetic abrasion, such as the particles given off by rotating wheels. Special clean room cranes counter this problem by using proper component surfaces and lubricants, making it possible to avoid undesirable abrasion products and vapours.
Other industrial sectors in which clean rooms are indispensable include optics and laser technology, medical research and pharmaceutical production. For production in these and many other fields, contamination by airborne particles is unacceptable due to its impact on product quality. To prevent this, clean rooms are subject to continuous monitoring of their temperature, humidity, air pressure and germ count. The use of clean room cranes reduces the risk of unwanted variations and contamination.
Clean room cranes – potential
The risk of contamination during production increases when standard cranes are used instead of clean room cranes. The costs resulting from contaminated products, such as those resulting from recall campaigns or repairs, can quickly reach astronomical levels. However, the costs of investing in a clean room crane can be amortised in only a few years. The costs of procurement and routine maintenance for a clean room crane are minimal compared with the potential costs of even minor recall campaigns. Even when only the costs of procurement and routine maintenance are compared for standard and clean room cranes, the investment in clean room cranes pays off after only a few years.
Special components for clean room cranes
Clean room cranes consist of a number of special components, some of which have found their way into other industrial cranes. For example, an automatic crane system that can reach a speed of 160 m/min at an acceleration of 1 m/s² has been built using the special wheels from clean room cranes. For such systems, speeds of around 40 m/min and accelerations of around 0.2 m/s² are typical. With the aid of the special wheels normally used in clean room cranes, such speed and acceleration increases can even be achieved without rack-and-pinion drives and other kinds of non-slip drives.
