A crawler crane has its boom mounted on an undercarriage fitted with a set of crawler tracks that provide both stability and mobility. Crawler cranes range in lifting capacity from about 40 tons to 3.500 tons.
The principal advantage of a crawler crane is its ready mobility and use, since the crane is able to operate on job sites with minimal improvement and stable on its tracks without outriggers. Wide tracks spread the weight out over a great area and are far better than wheels at traversing soft ground without sinking in. A crawler crane is also capable of traveling with a load. Its main disadvantage is its weight, making it difficult and expensive to transport. Typically a large crawler must be disassembled at least into boom and cab and moved by trucks, rail cars or ships to its next location.
Manufacturers of crawler cranes also offer many options and configurations to meet any job requirements including luffer, fixed jib, and heavy-lift attachments. Crawler cranes are powerful in use, such as the Liebherr cranes that are flexible in use and require very short set-up times.
