A cam hook is a specialized aid climbing tool that secures temporary anchor points in rock cracks. It is designed to torque into the crack when weighted, creating a highly stable, albeit temporary, placement. This specific type of gear is engineered for use on solid rock formations, such as granite, due to the significant force they exert upon placement.
How Cam Hooks Work
The effectiveness of a cam hook lies in its unique method of engagement with the rock:
- Deep Insertion: For optimal performance, the cam hook must be placed as deep in the crack as possible. This maximizes the surface contact and leverage, allowing the hook to engage effectively.
- Torquing Action: As the climber applies weight or tension to the cam hook, the tool initiates a torquing motion. This action leverages the geometry of the hook against the crack walls, driving it further in and creating a secure, outward-expanding force.
- High Force Application: It's important to note that this torquing process puts a lot of force on the rock. This characteristic necessitates its use only on rock types that can withstand such pressure without fracturing or crumbling.
Key Considerations for Cam Hooks
Understanding the specific applications and limitations is crucial when using cam hooks.
