Caterpillar has hired former Transportation Secretary Ray LaHood to serve as a consultant for the company.

He will advise the equipment giant on public policy but will not be lobbying, Caterpillar said.

{mosads}“Ray will assist Caterpillar in developing corporate strategies focused on identifying solutions to specific policy and communications challenges Caterpillar faces in the increasingly complex policy and business environment,” the company said in a statement. “Caterpillar will also benefit from LaHood’s deep expertise in infrastructure planning and investment and manufacturing in the United States.”

LaHood has kept a busy schedule in the private sector since stepping down from his Cabinet post last year.

He is also a senior policy adviser for law and lobby firm DLA Piper, the co-chairman of a bipartisan infrastructure advocacy group called Building America’s Future and a member of the board of directors for Proterra, an electric bus manufacturing company.  Last month, he became a senior adviser to an infrastructure investment firm.

The Obama administration requires former officials to wait at least two years before they can register to lobby on issues related to their former positions. LaHood was Transportation secretary from 2009 to 2013.

Prior to becoming a member of the Obama administration, LaHood served for 14 years as a Republican congressman for Illinois’s 18th District, which includes the center of Caterpillar headquarters in Peoria.
