AI Technical Summary

Technical Problem

Existing fall arrestors lack an active locking braking mechanism, limiting their applicability. Furthermore, the friction-driven operation results in high sliding resistance, reducing their passability.

Method used

The guide rail anti-fall assembly includes two pairs of anti-fall locking gear sets. The irregular gears are provided with avoidance surfaces and arc-shaped passage grooves. The drive rubber wheel is connected to the anti-fall pull rod. When an accidental fall occurs, the irregular gears rotate to reduce the diameter of the arc-shaped passage groove, thereby achieving active braking and locking.

Benefits of technology

This improves the applicability of fall arresters, reduces sliding resistance, and ensures high passability and safety on various flexible guide rails.
