The following are the core usage points of the rock climbing safety lock (main lock), compiled based on authoritative materials and practical operation suggestions:
1. Lock operation specification
Threaded lock : After closing the lock, the threaded lock must be tightened to prevent accidental opening. Some users dispute whether it needs to be retracted half a turn, but authoritative guidelines clearly require that it be tightened to a fully closed state to avoid loosening due to friction or impact.
Ordinary lock (non-threaded lock) : Ensure that the lock is closed. For temporary protection points, it is recommended to use two O-type locks with opposite openings for enhanced security.
2. Direction of force application and connection method
Longitudinal force principle : The main lock is designed to bear weight longitudinally (along the long axis), and transverse force or multi-directional force will significantly reduce its strength (possibly by more than 70%).
Avoid friction between the lock and the rope : Keep the opening side of the lock away from the rope contact point to prevent wear or accidental opening.
3. Maintenance and safety checks
Remove foreign objects : Sand and gravel in the thread should be removed in time to avoid affecting the locking function.
Regular inspection : After use, check for cracks, deformations or missing parts on the surface. Deal with corrosive substances immediately upon contact.
