Authentic User Feedback

🏗️ Construction Site Engineer Reviews

⭐⭐⭐⭐⭐ James Carter - Senior Equipment Engineer, Summit Construction
"We’ve been running the RUNMA Bx50-03 Gear Box on our electric wheel loaders since February 2025, and I’m thoroughly impressed. The 4WG180 transmission system delivers smooth, consistent power even under heavy loads. We’ve seen a noticeable drop in energy consumption—about 15% less than our old diesel units. The metal alloy construction feels rock-solid, and after 5 months of daily use in wet, dusty conditions, there’s zero sign of corrosion. The bolt-on design made retrofitting easy."
