Due to the low mounting height and high load capacity requirements, it was clear to the Blickle experts that heavy duty twin castors were the only solution. For this demanding application, our constructors developed a customised castor with cast iron and forged steel casing parts. The elastic polyurethane tread Blickle Besthane® Soft also offers good floor preservation and maximum operational comfort, with very low rolling resistance.
As conventional braking mechanisms could not be integrated into the castor, the specialists worked on a new solution, consisting of an electromagnetically controlled drum brake, using the dead man principle. This means that the brake is locked without power in normal condition, and is electromagnetically opened before the journey. The dead man's brake firstly acts as a travel brake and secondly as a locking unit, and represents a major safety function for the device as a whole. The Blickle castor solution was put through its paces on the client's testing premises; after a variety of braking, rolling and driving tests, and some minor constructive adjustments, the unit passed all tests. The CE declaration of conformity was then granted, giving the go ahead for a successful partnership.
