Mammoet Patents Width Expander for SPMTs

July 11, 2018 - Mammoet USA has patented an innovative widening adaptor that makes transporting heavy loads on self-propelled modular transport (SPMT) trailers safer and more efficient.

The U.S. patent is No. 9,834,263. The Canadian patent is No. 2,931,423.

The expander allows variable spacing of split SPMT trailers. It can expand the width of the trailers from 10’ to as much as 21’, offering more stability while retaining the same load capacity as the original-width SPMT.

Increasing the width of the loading platform without adding more SPMT trailer units makes transporting loads significantly more cost effective and safer due to the increased width.

Mammoet and Scheuerle jointly launched the first SPMT in 1984. SPMTs have had a significant impact on the way construction and maintenance projects in heavy industries are executed.

Mammoet has a unique fleet of SPMTs totaling more than more than 3,200 axle lines. The fleet is deployed by a team of professionals with unique levels of expertise in designing and delivering SPMT transport solutions.
