40-Ton Power Transformer Delivered from South Korea

The Challenge

Delivering a 40-metric-ton substation transformer from South Korea required careful coordination of breakbulk ocean freight and overweight inland trucking. At 88,000 lbs, the transformer exceeded standard highway weight limits, requiring overweight permits across multiple states and a properly configured heavy-haul trailer to distribute axle loads within legal limits.

Our Solution

We booked the transformer on a breakbulk vessel from Masan Port to the Port of Baltimore with proper blocking, bracing, and shock monitoring for the ocean transit. For the 400-mile inland leg, we deployed a 3-axle tractor with a 4-axle removable gooseneck (RGN) lowboy trailer — a 7-axle configuration rated for 130,000 lbs gross vehicle weight. Overweight and overdimensional permits were secured for Maryland, Pennsylvania, West Virginia, and Ohio, with police escorts required through each state.
