As a rule, bakeries, butchers, commercial kitchens and food transportation services have tended to stick to hard plastic wheels on their rolling equipment to meet the strict hygiene standards that prevail in the food industry. These require that no marks should be left on the floor and that wheels must be water-resistant, bearing the frequently damp conditions in mind. But hard plastic wheels also have their own disadvantages. They make a great deal of noise and their rigidity can take its toll on the transported goods. In stark contrast, with their quiet, floor-preserving properties, very low rolling resistance and high operational comfort, you would think polyurethane treads could give plastic wheels a run for their money. If only they were water-resistant! For this is what has prevented their use in the food industry in the past. Constant contact with water is known to corrode polyurethane wheels and thus produce dirt particles that could compromise the production environment.
But this Achilles heel could now be a thing of the past with the advent of the POBS series from Blickle. These innovative wheels offer the advantages of high-quality polyurethane treads and also meet the stringent hygiene standards of the food industry. The "Blickle Besthane Soft" reaction-cast premium polyurethane that Blickle has developed for the tread on its POBS series is said to be 100-percent hydrolysis-stable and corrosion-resistant. Blickle maintains that the material can even withstand contact with numerous aggressive chemicals. Not only that, but these new wheels can be used at temperatures from -25 to +70 degrees Celsius, support loads of up to 500 kilograms and offer very high dynamic resistance. The thick, soft, cast-polyurethane tread increases operational comfort, reduces running noise and leaves no scratches or marks in its tracks. The high-quality, rust-resistant chrome-nickel-steel housings of the finished casters and fixed wheels are equally able to withstand damp conditions. The wheels from the new POBS series have apparently performed so well in a number of customer projects that they will now be added to Blickle’s standard portfolio.
