The following table summarizes common classifications for mobile and truck cranes: Size Class Typical Length Typical Capacity Common Applications 20 – 30 feet 10 – 25 tons HVAC units, landscaping, small maintenance Medium 30 – 40 feet 25 – 75 tons Steel beams, utility poles, multi-story roofing Large 40 – 60+ feet 75 – 300+ tons Bridge sections, wind turbines, high-rise slabs Comparison by Crane Type
12 t capacity, 70 m radius, 2.0 m mast width.
: Most common; used in machine shops, handling ~50% rated capacity. crane sizes chart
: Highly mobile (road and off-road), typically ranging from 50t to 1,200t .

: Stationary vertical structures used for high-rises, generally lifting 8t to 64t .
Finally, at the absolute summit of crane technology are the "Super-Heavy Lift" cranes, often referred to as the "ring cranes" or "heavy lift gantries." These are rare, purpose-built giants used in the oil, gas, and nuclear sectors. With lift capacities exceeding 3,000 to 5,000 tons, these machines do not operate on standard roads and often require weeks to assemble. The charts for these behemoths read like structural engineering blueprints, dictating ground bearing pressure and wind speed limits that are irrelevant for smaller machines. The charts for these behemoths read like structural
Actual values vary by boom length, outrigger deployment, and configuration – always consult load chart.
: Constant high-capacity use, often in heavy manufacturing.
