Overspeed Governor

For high speed and high rise applications

Wittur Compact tension Weight

Research for innovative solutions and rigid control of product quality are key features of Wittur Safeties.

Wittur overspeed governors can cover a broad range of rated loads and speeds and can be applied both to machine roomless and traditional installations.

Our overspeed governors can be engaged at any point along perimeter of pulley and assure high life time due to limited pulley wear.

EOS



With the EOS you are welcomed to the 21st century with a  state-of-the-art electronic overspeed detection technology.
Thanks to the sophisticated electronics installed, the EOS reacts without any time delay.
EOS was the very first electronic overspeed governor introduced on the worldwide elevator market to enable a full range of different UCM situation for every installation need. EOS is compliant with requirements of Lift Directive and EN 81-20/ 50:2014

OVERSPEED GOVERNOR

OL25



The OL25 detects overspeed by its flyweight mechanism and engages the safety gear on the entire circumference of brake mechanism.
Simple mechanical design and remote control makes it the perfect choice not only for machine room but also for machine roomless applications.

Medium speed and rise governor

OL35 / E / M



The OL35 detects overspeed by its flyweight mechanism and engages the safety gear on the entire circumference of brake mechanism.
This brake mechanism is pre-adjusted and limits the brake-force to protect the synchronization of the safety gear from excessive stress to the linkage.
