The CCI basically is calculated as follows: “Radius * Lifting Height * Capacity”. The result CCI is in Te ∙ m. To clarify calculations a Liebherr LTM 1100-5.2 is used as an example.
How is Crane radius calculated?
Measure geometric components
- The standard calculation for maximum crane capacity is (r)(hC)/100.
- R = Radius between the ground and load.
- hC = Lifting height multiplied by the capacity.

How is crane load capacity calculated?
Crane Lifting Capacity Calculation
(r)(hC)/100, where r is the radius (distance along the ground to the load) and hC is lifting height times capacity. Capacity, in turn, is particular to each boom arm length and angle chosen, and must be looked up in a table such as the one in the Resources.
What is boom length of Crane?
The boom length of a crane refers to the main boom, not a jib or other attached equipment for the purpose of this description. Boom measurements are calculated using the following factors: The physical length of the boom. Angle of inclination during operation in a 360 degree environment.
How much can a 50 ton crane lift?
Produced by Terex, the American HC 50 is a hydraulic crawler crane that’s nimble, yet, very capable of performing tough tasks. It has a 50 ton (45.4 t) max lift capacity, 160 ft. (48.8m) max lift crane boom length, and a 130+40 ft. (39.6+12.2 m) max lift crane boom & Jib length.
How much can a 40 ton crane lift?
It’s easy to tell how much a particular hydraulic truck crane can lift just by the name of it: A 40-ton crane can lift 40 short tons (80,000 pounds or 36,287 kilograms).
What does a 100 ton crane mean?
100 ton means, that theoretically the crane could lift one metre from the center of the column 100 ton. … The base formula for the Crane Capacity Index is: * For each main boom length at each radius the “Lifting height*Capacity” is calculated.
What’s the best way to find the load capacity of a crane select the best option?
Call the manufacturer Ask co-workers Look at the load capacity chart in the cab It’s best determined by lifting a load.
How far can a 30 ton crane reach?
Hydraulic Truck Cranes
Hydraulic trucks range from 30 to 600 ton capacity and feature a hydraulic boom that can reach lengths up to 200 feet.
What is the load chart?
: a schematic and graphic device to indicate the amount of authorized work yet to be performed by a machine, a group, or any other producing unit in a factory.
What is load radius of Crane?
‘ indicator on the left axis represents the radius, the distance from the center pin to the center of the load. EXAMPLE: You need to lift a load of 15 tons (30,000 pounds) a distance of 25 feet. The distance is measured from the center pin of the crane to the center of the load.
Can you use an excavator as a crane?
Powered earthmoving equipment like excavators, backhoes and front-end loaders are often used like a mobile crane to lift and move freely suspended loads.
How much can a 10 ton crane lift?
So there is no one simple answer to the question, “how much weight can a crane lift?” On average, most cranes can lift loads between 10 and 60 tonnes.
How much can a mobile crane lift?
Our heavy crane selection can lift anything from 200 to 700 tonnes, while still being fully mobile. Although this weight cannot be lifted to the height of a tower crane, sometimes height has to be substituted for unrivalled lifting power.
What is the black line on a crane load chart?
The bold line on the chart represents the separation of structural strength and stability. Any capacities below the bold line are limited by the crane’s stability. Any capacities above the bold line are limited by the structural strength of the crane.
