From applications for bending machines, track laying machinery or tunnel boring machines, company ROLLSTAR has already accumulated several years of experience in the manufacturing of holding brakes at standstill.
The combination of service brakes from well-known manufacturers such as KTR Systems GmbH and ROLLSTAR planetary gearboxes opens up new application fields in the area of dynamically controlled braking processes in addition to the static braking and holding processes.
For a 2019 realised order of a winch drive in a large-scale aluminum foundry, a three-stage ROLLSTAR planetary gearbox designed for a nominal torque of 350'000 Nm was adapted for the installation of a hydraulically operated KTR disc brake.
In the mentioned foundry application, gearboxes and brakes are exposed to the most adverse environmental conditions, including 90% relative humidity and temperatures around 80°C. In addition to the drive components, the sensors for condition monitoring of the system must, of course, also be designed in the corresponding IP protection classes and standards. With the implementation of high-quality materials, precision work in manufacturing and engineering know-how, a quality product of the ROLLSTAR brand is created, customized and optimally adapted to the requirements of the application.
On request ROLLSTAR does engineer and build drives suitable for installation of service brakes with either hydraulic or electromechanical actuation. We ar happy to help you for your drive technology projects and remain at your disposal for any further
