RINGSPAN Overload Clutches are mechanical safety devices which disconnect the output from the input when a pre-set limit value has been reached. Thus they protect against damage and stoppage times caused by overload.
For over 50 years RINGSPANN has manufactured Overload Clutches with an excellent track record in the most diverse applications. Today RINGSPANN offers a comprehensive range of positive and friction Overload Clutches.
Positive Torque Limiters
Positive SIKUMAT® Torque Limiters are used as precision safety devices in installations and machines. The unsurpassed variety of working principles offer optimal solutions to every type of application.
Friction Torque Limiters
Friction Torque Limiters are available in two designs which are RIMOSTAT® Torque Limiters and Belleville Spring Torque Limiters
RINGSPANN has designed a series of Force Limiters, outstanding in that forces up to a certain size can be transmitted in both directions completely free of play and rigid. On exceeding the pre-set disengaging force, the power of the force is interrupted and the output part is no longer driven. After the overload has been cleared the driving part and the driven part are aligned towards each other and the Force Limiter re-engages automatically.
Can be fitted with non-contact proximity switch to give early warning of reaching a certain force, or disengaging signal.
