Stainless steel electric belt hoist for the food industry

12.05.2021 von Achim Altmann

Material and construction as well as design must be such that the equipment cannot contaminate foodstuffs through abrasion or lubricants. Another prerequisite is the possibility of easy cleaning with highly corrosive cleaning agents. ALTMANN's new hoist is made almost entirely of stainless steel. However, the main feature that predestines it especially for the food industry is the maintenance-free load belt. In contrast to chain or rope, this is absolutely lubrication-free and therefore non-greasy with no abrasion.


Discreetly installed drives

The discrete drive technology developed by ALTMANN is an ingenious design feature that prevents contamination through abrasion. Among other things, it is based on a low-abrasion material combination for the deflection and guide rollers. In addition, the integration of the electric belt hoist and drive in closed housings absorbs any abrasion. The decentralised control system can either be enclosed together with the hoist or installed in a separate location. Since all travel axes are equipped with a frequency converter, the belt hoist can accelerate steplessly. The hoist can be operated either via a radio remote control, an automatic control or a cable-connected manual control unit.

Designed for continuous operation

The completely enclosed assembly with its smooth surfaces is particularly time-saving to clean, making the new electric belt hoist suitable for 3-shift operation in production facilities where perishable foodstuffs such as milk are processed quickly. Wet cleaning in such factories is also facilitated by the drainage holes in the shafts in which the cable drag chains are installed. Because the water does not accumulate due to these holes, no biofilm can form. The new stainless steel electric belt hoist is currently in operation in a cheese dairy, where it moves loads of 1 ton, having been designed for a load capacity of up to 2 tons. For this use, the hook block was also reeved directly into the crossbeam in order to reduce the actual C dimension of 200 mm by almost half.
