Tower Safety • Forces Are Not Hidden
Tower Rigging Lab 2.0
Visualizing the Physics of Safe Lifting
The Tower Safety Rigging Lab was created to help climbers, riggers, rescue professionals, and instructors understand why forces behave the way they do.
Every simulator is designed to visualize load paths, vector forces, pulley reactions, and resultant loads using interactive engineering models built for education.
