In Europe the All Terrain crane has been the mainstay of most crane rental fleets for more than 30 years. It is easy to think it was always the case yet they only began to appear in the late 1970s and never took off until the 1980s. Until then most European rental fleets were made up of truck cranes while in North America it was a combination of truck and Rough Terrains, the vast majority less than 50 tonnes.
