  • 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.
  • Down-direction only
  • Best mechanical overspeed governor for mainstream applications
  • External encoder option for absolute car position acquisition
  • Continuous traction between rope and pulley during tripping prevents excessive wear to the rope
  • Safety gear is always activated on a pre-determined force
  • Remote control for MRL- applications
  • Various installation possibilities outside shaft, wall, guide rail …
  • Upside down applicable
  • Available for all global major elevator norms and directives
  • Available as a package with tension weights, accessories, fixings
