About Us

William G. Zimmermann Mark Alspaugh

William G. Zimmermann and Mark Alspaugh, P.E. founded Overland Conveyor Co., Inc. (OCC) in 1993. Both principals had extensive belt conveyor backgrounds with manufacturers such as The Goodyear Tire & Rubber Co. and Continental Conveyor & Equipment Co. prior to this endeavor.


The goal was to build an excellent technical support consulting company specializing in handling bulk materials with belt conveyors. Emphasis was put on integrity in both engineering and personal relationships with clients. OCC established several strategic alliances with component manufacturers and service providers who rely on belt conveyor users for the majority of their sales or service. These companies represent industry leaders who are looking for ways to add value to their components

Allen V. Reicks, P.E.

In May of 2000, OCC was fortunate to attract Allen V. Reicks, P.E. who had been Chief Engineer for Precision Pulley and Idler. Mr. Reicks brought strong experience to the team in manufacturing and component design and has since become Director of our Research and Development efforts, Vice President, a Board member and equity partner.



Thomas Martin

In April of 2002, OCC merged assets with Martin Consultants Inc and Thomas Martin, P.E.. Mr. Martin brought years of experience in mine design and economic evaluations including route optimization, feasibility studies, risk analysis, budgetary estimates and preparation of bid proposals.



Today, OCC is an association of 17 belt conveyor professionals dedicated to excellence in belt conveyor design, engineering and troubleshooting using an integrated systems approach. OCC has established long-term relationships with mining companies who rely on belt conveyors to transport bulk materials. Services provided include operations driven system integration of conveyor components through advanced system modeling and simulation, performance monitoring and preventive maintenance.

In 2005, OCC expanded from its consulting base to being a leading worldwide supplier of belt conveyor engineering software tools. Its Belt Analyst™ suite has become the international standard used by mining engineers, consultants, engineers, manufacturers and service providers in all bulk materials mining and processing industries.

In August 2006, OCC moved to its current location with 7,000 sq-ft of office and a fully equipped training center.
