Bob Renegar

President

As President and Chief Executive Officer of Renegar-Driggers Machinery, I bring 53 years of experience in the crane industry. I began my career in 1974 with a Tennessee dealer representing Clark-Lima and Pettibone cranes. In June 1985, I founded Renegar Machinery Corporation as the P&H Cranes dealer for Tennessee. Four years later, I joined business partner Terry Driggers Sr. to establish Renegar-Driggers Machinery. Throughout my career, I have successfully represented many of the industry’s leading manufacturers, including Terex, Demag, Tadano, and Kobelco. My commitment has always been straightforward: provide dependable equipment, stand behind every crane throughout its working life, and treat customers and vendors as long-term partners. That approach has helped Renegar-Driggers Machinery grow into a respected leading distributor within the crane industry.

Our Story

Renegar-Driggers Machinery was founded in 1985 by Bob Renegar and Terry Driggers Sr., two experienced leaders with deep roots in the crane and heavy-equipment industry. Before launching the company, Terry Driggers Sr. served as Chief Financial Officer of Stafford Crane Group, while Bob Renegar was Vice President of Sales at H.H. Hooper. Together, they combined their financial, operational, and sales expertise to build a company focused on dependable crane equipment, parts support, and long-term customer relationships. Originally established as a P&H crane dealer, Renegar-Driggers Machinery has continued to grow and evolve throughout the decades. The company expanded its product support to include several of the crane industry’s leading manufacturers and has proudly served major contractors, fleet owners, and industrial companies across the United States. Today, the company’s legacy continues under the leadership of Terry Driggers Jr. and Bob Renegar. We remain committed to the same principles on which the business was founded: trusted industry knowledge, responsive service, reliable crane and parts solutions, and lasting partnerships with customers throughout the heavy-lifting industry.
