Truck cranes range in lifting capacity from about 14.5 short tons (12.9 long tons; 13.2 t) to about 2,240 short tons (2,000 long tons; 2,032 t). Although most only rotate about 180 degrees, the more expensive truck mounted cranes can turn a full 360 degrees.
How is crane capacity calculated?
Measuring the dimensions of this triangle will allow you to achieve an accurate crane load calculation.
- 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.

What is the lifting capacity of a crane?
It’s important to note that the maximum capacity is always measured by the shortest lift, usually over the rear of the crane, and with the outriggers fully extended. While the Terex RT345 has a maximum capacity of 45 tons, lifts at any distance or height drops the maximum capacity dramatically. 3.
What is crane capacity index?
In this document is explained how a “Crane Capacity Index” (CCI) can be determined. 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.
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.
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 many tons can a 40 ton hydraulic crane lift?
How much can a hydraulic crane lift? Hydraulic truck cranes vary in lifting power. 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).
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 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 crane can lift the most weight?
Guinness World Record
Taisun holds the world record for “heaviest weight lifted by crane”, set in Yantai on April 18, 2008 at 20,133 metric tonnes (44,385,667.25 lb) by lifting a barge, ballasted with water.
What is 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 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.
How do you calculate safe lifting load?
Calculating the Weight of a Load
- Step 1: Determine the Volume of the Load. Rectangle/Square: Volume = Length x Width x Height. …
- Step 2: Determine the Material You’ll Be Lifting. The table below can be used for approximate weight values of common loads and materials: …
- Step 3: Determine the Weight of Object.

How much can a 500 ton crane lift?
About the 500-Ton Crane
The telescopic boom can extend from 15.4 metres to 60 metres and, with the lattice jib assembled, the 500-ton crane has a hoist height of 130 metres. The crane has a lifting radius of 100 metres and the load capacity maxes out at 400 tons.
How much can a 200 ton crane lift?
19,500lb Cap. 1,250lb & 300lb Cap.
How is SWL of Crane calculated?
To calculate the SWL in kilograms of FSWR square the rope diameter (D) in millimetres (mm) and multiply by 8.
- Formula: SWL (kg) = D2(mm) x 8.
- Formula: D(mm) = √L(kg)
