Carabiners and hooks

[Everett33]

Back in 2010 to climb we placed a custom aluminum hook above the bar using a telescoping PVC arm. We then retracted the arm, leaving the hook on the bar, and then winching ourselves up with a cable.

In 2013 we made two custom spring loaded latch mechanisms to grip on to the 10-point bar of the pyramid from below. The latches were extended and retraced with 2 pneumatic cylinders.
