Abstract
A locking system for a vertical cable shuttle is disclosed. The locking system comprises a housing defining a guide path and slideably attached to a guide member. A braking lever configured to engage the guide member. The braking lever comprises a shock absorber fabricated along the braking lever and configured to absorb shocks during a fall. Further, a braking configured independent from the braking lever. The braking element is a logarithmic spiral structure configured to rotate into engagement with the guide member during the fall, and defines a constant slope angle for gripping of the guide member. The braking element having a braking surface to provide contact surface area with the guide member during the fall.

A locking system for a vertical cable shuttle, the locking system comprising:
- a housing defining a guide path and slideably attached to a guide member;
- and
- a braking element rotatably mounted within the housing, the braking element having a logarithmic spiral structure configured to rotate into engagement with the guide member during a fall,
- wherein the logarithmic spiral structure of the braking element defines a constant slope angle for gripping of the guide member, and
- wherein the braking element is configured independent from the guide member and is initiated by acceleration of the locking system during the fall such that the logarithmic spiral structure rotates as the acceleration of the locking system increases during the fall.
