Loeffler Engineering Group (LEG) utilizes the "Networking Techniques" that have proven successful in product and system sales to provide engineering services. Although we are a small engineering firm we can assimilate an impressive team of experts. By using email, fax and overnight mail we can transfer written information, data, drawings, digital photos & scanned documents within minutes and therefore address project requirements immediately. This flexibility enables us to address all phases of complex bulk materials handling projects.
Our approach to design provides us the flexibility of selecting the best talent available without the burden or constraint of full-time employees. We use the latest commercial software including AutoCad, Word, Excel, Power Point & STADD. Our own in-house software for conveyor design supplements these programs. Our designs are in accordance with the 6th addition of CEMA and the latest safety standards of ASME committee B20, OSHA and MSHA.
Using this approach we can provide the highest quality service at a competitive rate.
Our engineering team provides all engineering disciplines needed for a complete materials handling system. Our design services can include belt conveyors, machine design, marine structures, civil, structural, geotechnical, mining and electrical that may be required by the project. Our experience has been used in most industries that utilize belt conveyors.
Today's economic conditions have also promoted the use of used or surplus equipment. This choice may be due to either financial or schedule constraints. We therefore have many sources for pre-owned equipment, which can be retrofitted or modified, based on system requirements. We can also arrange to have this equipment refurbished. Additionally we can provide inspection, asset appraisals and construction management from acquisition to start-up.
We pride ourselves on servicing our client's needs to the fullest satisfaction and the successful results are demonstrated by repeat business and referrals from our clients. We would appreciate the opportunity to discuss with you your next project no matter how large or small.

Legal Experience & Services
In 1993 Loeffler Engineering Group expanded its services to include litigation support. Our first 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 a restraint of trade case. For this case, we had to prepare a system design and cost estimates dating back 25 years using past technology and costs. We also developed courtroom presentations combining 3d AutoCAD with photography. After working on these two cases, litigation support became a sector of our engineering activity.
Since then, Frank J. Loeffler Jr., P.E. has had experience in the following kinds of cases: Product Compliance, Restraint of Trade, Conveyor Guarding, Machine Guarding, Conveyor Fires, Personal Injury, Product Liability, Patent Infringement, Code Compliance, Asset Appraisal.
