In 1991 Mr. Loeffler started Loeffler Engineering Group as a Manufacturers’ Representative sales organization. At the request of several clients, engineering services were added. These services included conceptual system design, estimating and specification writing. Although a small firm, “networking” was used to organize a team of worldwide talent on an as-needed basis. LEG completed studies and specifications for systems valued at up to $100 M.
In 1993 Loeffler Engineering Group expanded its services to include litigation support. Our litigation experience began when a former employer of Mr. Loeffler requested us to assist their attorneys in a defense arbitration. They had designed a shiploader that their client claimed failed to meet the design specifications. We provided the technical support that enabled their attorneys to present this case.
The following year, we were retained by a plaintiff’s attorney to design a bulk loading / unloading terminal to be used in an antitrust case. For this case, we had to prepare a system design and cost estimates dating back 25 years using technology and costs from the respective time periods. We also developed courtroom presentations combining 3d AutoCAD with photography (see above exhibit). After working on these two cases, litigation support became a sector of our engineering activity.
Loeffler Engineering Group (LEG). LEG is a an engineering firm specializing in the handling, transport, storage and loading of unit and bulk materials by conveyor systems. LEG was founded in 1991.
We specialize in the design of materials handling systems and conveyors of various types including: belt, roller, slider, overland, pipe, steep angle, screw, drag, bucket elevators and pneumatic. We also design the specialty mobile machines, (track, rail, and wheel mounted) such as: stackers, reclaimers, snow loaders, mobile screening plants, self-unloading trains, self-unloading ships, ship unloaders and shiploaders. Our design experience also includes auxiliary process equipment such as: truck & rail car loading and unloading systems, thaw sheds, dust collection & suppression systems, feeders, bins, hoppers, scales, mixers, screens, and crushers.
Some of the industries for which we have applied these systems include: power, mining and quarrying, aggregate, grain, aluminum, steel, minerals processing, cement, pulp & paper, ports & intermodal terminals, chemical plants, concrete block and brick, ore heap leaching, refineries, hazardous waste, recycling & composting.
Additionally, we have provided expert reports, opinions & testimony for cases involving antitrust, plant asset reappraisal, conveyor injuries, product liability, guarding, confined space, code compliance, equipment failures, patent infringement, conveyor fires, and dust explosions. We have also conducted conveyor system safety inspections.
Frank J. Loeffler Jr., P.E. is a licensed engineer in six states. He is also an active member of the conveyor safety committee’s ASME B20.1, ASME B15.1 & CEMA.
