Hertz Global Holdings might buy as many as eight equipment rental companies this year to help minimize the company’s reliance on its car-rental business, CEO Mark Frissora said this week. Bloomberg News is reporting that Hertz is looking at equipment rental companies in the oil and gas exploration markets, pump and power generation and entertainment industries.

Over the past year, Hertz has acquired a diverse range of rental companies including Cinelease, a grip and lighting rental specialist; northern California’s DW Pumps; the offshore equipment rental division of Delta Rigging & Tools; energy rental specialist WGI Rentals, based in Williston, N.D., near the Bakken shale oil region; Forces Inc., a power generation specialist in the Chicago area; and 24/7 Studio Equipment Rentals, Burbank, Calif.

Based in Park Ridge, N.J., Hertz Equipment Rental Corp. is No. 4 on the RER 100.
