Box Build Excellence for Heavy Forestry Equipment
From precision wiring to cost-saving component optimization, we engineered a box build that keeps forestry crews moving.
The Situation:
GS Global Resources (GSGR), a Wisconsin-based specialized engineering company, needed a reliable partner to build a complex electromechanical box build with integrated wire harness for their client’s heavy forestry equipment. These massive machines operate in demanding conditions where reliability isn’t optional; crews depend on them in remote forest locations where equipment failure means costly downtime and safety risks.
The project presented significant complexity: multiple wire connections, tight space constraints, and the need for ruggedized assembly that could withstand the vibration, temperature extremes, and harsh environment of forestry operations.
The ETI/ACH Solution:
Our Precision-Built Approach
We assigned our best team members to the project, including Jackie (pictured below), one of our most skilled wire harness technicians. What could have resulted in a tangled mess of wiring became a meticulously crafted assembly. Every wire was routed with precision, every connection optimized for both performance and serviceability.
But we didn’t stop at simply following specifications. Our sourcing specialist Beau identified an opportunity to reduce costs by modifying an existing component in-house rather than sourcing it externally and we were able to cut the cost of that component to 25% of its cost online. This is how we approach every project, as a true partner looking for ways to add value, not just execute orders.
The Partnership Advantage
When GSGR needed the completed assembly, our Midwest location delivered a competitive advantage that overseas suppliers simply can’t match. No ocean freight delays, no customs complications, no 12-hour time zone differences when questions arise. Just reliable, fast delivery between two Midwest manufacturing partners.
