Overhead Crane Consulting Is All We Do!

We do overhead electric bridge cranes, sometimes referred to as EOT cranes. This encompasses the design, fabrication, installation, operation, maintenance and inspection of overhead cranes and crane runways.

Let me emphasize, we are a crane consultant only, we do NOT sell overhead cranes and have NO financial relationships with any crane sellers. NONE!

Our experience also includes life long participation in the applicable specification as listed in OSHA 1910.179 and OSHA 1910.6. Primary among these are ASME/ANSI B30.2 Overhead and Gantry Cranes (of which we are a member) and CMAA 70/74/78/79

A Lifetime of Experience

I started out learning to weld at Dearborn Crane, our family owned crane manufacturing company when I was 15 years old. I spent my high-school summers building cranes in the shop and my college summers working on a field installation crew.

After graduating from Notre Dame, I joined Dearborn full time and worked as a draftsman, crane designer, salesmen and general manager.

I’ve spent my whole adult life “hip deep” in every aspect of the crane business. I can’t say I know everything about cranes, but one advantage of being in the business this many years, is knowing who to call when I don’t know the answer.

 Overhead Crane Seminar

Speaking, Teaching, Writing…

Speaking/Teaching
Several times a year, I speak at conferences including the CCAA (Crane Certification Association of America), the CMAA (Crane Manufacturer’s Association of America, the ASME (American Society of Mechanical Engineers) and the AIST (American Institute of Steel Technology) to name a few.

Writing
I frequently write for the Crane College section of this website as well as various national and international industry magazines.

Industry Involvement

I am the past Executive Director of the CCAA (Crane Certification Association of America) a group of professional crane surveyors dedicated to the professionalism of the industry and the safety of crane users.

I was formerly on AIST (American Institute of Steel Technology) Subcommittee No. 6, Electric Overhead Traveling Cranes for Steel Mill Service and Subcommittee No. 13, Guide for the Design and Construction of Mill Buildings (with overhead cranes). These are the committees that write the specs for the US steel industry.

I am currently a member of ASME/ANSI B30.2 Overhead and Gantry Cranes, the committee that writes the standards for the U.S. overhead (EOT) crane industry. B30.2 is the specification that OSHA 1910.179 is based on and OSHA 1910.6 incorporates it fully by reference.
