Core Features

Circular Bidirectional Ratchet System

The Youlong Fall Arrester features an alloy steel circular ratchet wheel with adjustable movement modes:

Bidirectional Mode: Moves freely up and down with the user, ideal for climbing and positioning
Unidirectional Mode: Moves upward only; downward movement is blocked. In case of sudden load, the device locks instantly

LOCK Button Adjustment

The LOCK button allows easy switching of the ratchet direction:

Locked: Upward movement only (unidirectional mode)
Unlocked: Free bidirectional movement

This design enables users to switch modes flexibly, balancing efficiency and safety.

Instant Locking Under Load

In bidirectional mode, if a fall occurs, the device locks immediately, preventing further descent.
The working load can reach up to 140 kg.

Unlocking Method

If the device locks after a fall:

Press the fall arrester
Push the ratchet slightly upward along the rope
After hearing several “click” sounds, the lock is released

This ensures the device can be reset and reused after activation.

Dyneema Energy Absorber

The Youlong Fall Arrester is used with a Dyneema energy absorber:

Impact force: ＜6 kN
Outer plastic film: Holds the absorber in place and should not be cut

Available sizes:

30 cm: 138g
40 cm: 168g
