Coon Rapids Students Engineer Safer Spanner Wrench

Monday March 31, 2025

Coon Rapids High School Engineering Design & Development students were challenged by Aggressive Hydraulics to solve a real-world problem—design a safer, more ergonomic spanner wrench for hydraulic cylinder assembly.

The result? Five impressive concept solutions that improve safety, efficiency, and usability in the shop. From all-in-one tools to adjustable designs and 3D printed ratchet systems, these students brought innovation and creativity to the table.

Along the way, they toured Aggressive Hydraulics’ purpose-built facility and saw what it means to be Made in America and Engineered to Move Your Business™.

Aggressive Hydraulics is proud to support student innovation and provide real-world opportunities to the next generation of engineers.
