OL35
- Engagement of the safety gear in down direction
- Overspeed contact operated in up and down direction
- Outline dimensions do not change over whole speed range
- Tripping possible at any point along perimeter of governor pulley
- Guaranteed minimum rope pull through force 500N
- Pull through force created by inbuilt friction brake exerting brake torque to governor pulley
- Suitable for conventional elevators with machine room but also for MRL-elevators
- Wide range of options available as remote control, base plates, tension weights, providing maximum flexibility
- Component certified according to directive 95/16/EC (Lifts)
- Meets code requirements of EN81 and ASME A17.1

Electronically operated overspeed governor
EOS
- Uni- or bi-directional operation
- Remote tripping/reset
- Continuous measurement of position, speed and acceleration: higher accuracy of measurement compared to conventional governors
- Outline dimensions do not change over whole speed range
- Activation possible at any point on perimeter
- Self-monitoring system
- Prepared for BUS-interface connection to controller
- Compliant with EN81-1/2:1998 / A1:2005 (PESSRAL)
Advantages compared to traditional devices
- Protection against uncontrolled car movements
- Faster action
- Acceleration-based tripping
Available options
- Remote control for application in MRL-elevators
- Anti creep-device for unintended movement protection
- Encoder output for positioning system
- Temporary reduced tripping speed, e.g. for construction time and maintenance
