Grant Leum literally recreated the wheel.

When he struggled to find an acceptable tire to support a 30,000 lb. capacity mobile loading dock design, he crafted an exclusive “never flat” solid wheel.  In fact, Leum created an entire category of architecturally-sound loading dock solutions that are removable and relocatable to fill a significant need for flexibility in materials handling.

Tapping this relentlessly inventive Dockzilla spirit, Leum has designed loading dock configurations with insights and nuances for countless loading applications, such as: remote loading, wider loading decks, high-capacity implement loading, less manual engagement, loss of interior floor space, forklift tire damage, safeguarding rail docks, and more. His products have been nominated for Plant Engineering’s “Product of the Year” award and he has been awarded more than 50 U.S. and International patents.

Today Dockzilla designs are integrated into “best practice” operating procedures for some of the world’s largest companies including Amazon, FedEx, Kroger, Mercedes-Benz. SpaceX and many more.

The youngest of six children, this Wisconsin farm boy learned the mechanics of heavy equipment, job site safety, and maintenance (along with a few Norwegian cuss words) working alongside his father. Leum’s natural artistic and mathematical instincts led him to the prestigious Milwaukee School of Engineering, where he received a degree in structural engineering.

He held engineering and management positions in materials handling at Rite Hite Corporation, becoming well-versed in loading dock design, architectural safety codes, and concrete construction. Leum formed his own company, initially named Leum Engineering, Inc. in 1998.
