Overspeed Governor

OL35-NA, OL35E-NA



  • 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
  • Meets code requirements of ASME A17.1
