Drum couplings are typically used in cable drum drives of lifting devices, winches or storage and retrieval machines. With its TNK product series, RINGFEDER® offers a comprehensive and powerful standard program as well as customised special solutions for these applications. In the case of a special storage and retrieval unit, an extremely compact and flexible variant of a drum coupling was specially designed. The key requirements specified by the customer were a minimum installation space and the option for the adaptation to different shaft diameters. The innovative RINGFEDER® solution: A drum coupling with an installation dimension of only 160 mm including an increased torque range as well as a modular locking assembly which is provided with a constant outer diameter in the drilling range of 28 to 60 mm.
Maximum torque transmissions, extreme environmental influences and different operating times and loads are the typical framework conditions in the fields of crane and lifting technology. The requirements to be met by the drive components used to ensure reliable and low-maintenance operation and to completely rule out downtimes as far as possible are therefore tremendously high. That's why users all around the globe rely on top-quality coupling and locking device systems designed by RINGFEDER®: Durable barrel couplings for a variety of reel applications, highly elastic shaft couplings as connection elements between the drive and output, robust locking devices for fastening belt and gear wheels or shaft-mounted gearboxes – customers are always provided with perfectly suited standard and special solutions matching the requirements of their specific application.
