TNT said the purchase, for an undisclosed sum, offered significant growth potential for combined operations. Both companies have a focus on crane lifting services to the energy sector, with Rent-A-Crane operating in Oklahoma and northern Texas.

TNT cited many benefits to the deal, including customers seeing an expansion in service, manpower and resources.

Kregg Lunsford, TNT president, said: "We are extremely excited about the growth opportunities that Rent-A-Crane brings to TNT. Not only is the company strong in the oilfield industry but they have a robust customer base in the infrastructure, power and commercial markets that we serve across all of our branches in the South and Southeast United States."

Gary Rohlmeier, Rent-A-Crane CEO, said the deal would provide the company’s customers with a large and diversified offering of lifting and rigging services.

TNT is one of North America’s largest crane service providers, offering hydraulic truck, all-terrain and crawler cranes with lifting capacities up to 1300t, while Rent-A-Crane has a fleet of more than 20 mobile and all-terrain cranes.
