Jackjaw 200 (Stake Puller)

What happens here

Bob Andersen from Construction Accessories Inc. presents the Jackjaw 200, a highly popular stake puller for concrete form pins. The tool is demonstrated with a simulated nail stake embedded in a wooden block. When the handle is raised, the jaws open; when lowered, they clamp onto the stake. Pushing down on the handle leverages the stake straight out of the ground. This system works by increasing leverage to pull stakes out of the ground faster, easier, and safer, preventing back injuries and bent stakes.

Goal: Understand the functionality of the Jackjaw 200 stake puller.
