Carry deck cranes are relatively small and designed with four wheels. They can rotate 360 degrees, making them portable and versatile. They are capable of moving and loading a variety of materials on job sites and come in sizes ranging from 2.5 tons to 30 tons. Most operated all terrain cranes range in size from 100 tons all the way up to 400 tons or more. (A few are in the 10- to 99-ton range.) Typically not as mobile or nimble as carry deck cranes, these cranes are usually transported on large, heavy-duty rigs.
