Shipping Industrial Motors Freight Class Guide
Industrial Motors typically classify around Class 60, in the 25-35 lb/ft³ density range. Electric industrial motors, crated.

Shipping Industrial Motors the Right Way
Windings and Bearings Are Shock Sensitive
The copper windings and precision bearings inside an industrial motor can be damaged by shock or vibration that leaves the outer housing completely undamaged, so internal bracing inside the crate matters as much as the crate's outer construction.
Crate Strength Should Match Motor Weight
Industrial motors range widely in size and weight, so crate construction needs to scale accordingly, since a crate built for a smaller motor will not reliably support a larger, heavier unit through repeated handling and transit.
Weight Drives Load Planning More Than Class
Because industrial motors are so dense, a load of crated motors can approach legal weight limits while using a relatively small share of the trailer's floor space, so dispatch plans these loads around weight distribution first.
Industrial Motors: What Carriers and Shippers Look For
Electric industrial motors are dense, heavy, and packed with copper windings and precision bearings, which puts them toward the denser end of the industrial equipment freight classes. Weight is the dominant planning factor for motor freight, and protecting the windings and bearing surfaces from shock damage during transit matters just as much as the crate's outer strength.
Why Industrial Motors Classify Around Class 60
Crated electric industrial motors typically run 25 to 35 pounds per cubic foot, which puts most shipments in the Class 60 range under the standard density table. That density comes from copper windings, a solid steel housing, and precision bearing assemblies packed tightly into a compact frame, landing industrial motors among the denser, less expensive commodities covered on this site.
Crating and Internal Bracing Tips
A motor's windings and bearing surfaces are precision components that can be thrown out of tolerance by shock or vibration during transit, even when the outer housing and crate show no visible damage. Internal bracing that keeps the motor from shifting inside the crate protects these components far more effectively than external cushioning alone.
Crate construction should scale with the specific motor's weight and size, since a crate designed for a smaller unit will not reliably hold up under repeated handling with a larger, heavier motor. Shippers moving a range of motor sizes should adjust crating specifications model by model rather than using one standard design across the whole line.
Equipment and Handling Notes
Dry van is standard for industrial motor freight, and no temperature control is needed under normal shipping conditions. Because motors are dense and heavy for their footprint, drivers should distribute weight carefully across the trailer when hauling multiple units, and forklift operators should handle motor crates at rated capacity throughout loading and unloading.
Common Shipping Mistakes
The most common mistake is relying on external crate strength alone without internal bracing, which leaves windings and bearings vulnerable to shock damage that never shows up as visible crate damage. The second is underestimating how quickly motor freight adds up in weight, which can push a load to its legal weight limit while the trailer still has plenty of unused floor space.

“Motor freight is heavy for its size in a way that catches new drivers off guard. I check weight distribution first on every load with multiple motor crates.”
“I've learned to trust internal bracing more than a thick crate wall. The windings inside are what actually fail if a motor gets bumped hard enough.”
