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?
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 do you calculate lift capacity of a crane?
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.

How much a crane can lift?
The maximum load that the crane can lift is 18 metric tons (39,690 pounds), but the crane cannot lift that much weight if the load is positioned at the end of the jib. The closer the load is positioned to the mast, the more weight the crane can lift safely.
What is the net capacity of a crane?
Gross Capacity Versus Net Capacity
The actual load the crane can lift is referred to as the “Net Capacity”. The maximum load must never exceed the crane’s Net Capacity! The Gross Capacity must include the weight of anything and everything that is mounted or stowed on the boom of the crane or hanging from the boom tip.
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).
How is SWL calculated?
SWL or WLL are calculated by dividing MBL by a safety factor (SF). An example of this would be a chain that has a MBL of 2000 lbf (8.89 kN) would have a SWL or WLL of 400 lbf (1.78 kN) if a safety factor of 5 (5:1, 5 to 1, or 1/5) is used.
How do you calculate lifting load?
Take the total weight of the load and divide this by the number of legs supporting the load. For example, assume a 2,000 pound load is to be supported by 2 legs of a sling. The above will give a total minimum weight on each leg of the sling of 2,000 pounds divided by 2 legs or 1,000 pounds.
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.
How much can a 200 ton crane lift?
19,500lb Cap. 1,250lb & 300lb Cap.
How much can a small 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 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 biggest crane lift?
The Liebherr LTM 11200-9.1, built by the German company Liebherr Group, is the most powerful mobile crane ever built. It also has the longest telescopic boom in the world, which extends fully to 100 meters. It’s set on a double cab truck and can lift 1200 metric tons – that’s nearly 700 automobiles.
What are the most common types of crane accidents?
OSHA’s analysis of crane accidents identified the major causes of crane accidents as:
- boom or crane contact with energized power lines (nearly 45% of the cases)
- under the hook lifting device.
- overturned cranes.
- dropped loads.
- boom collapse.
- crushing by the counter weight.
- outrigger use, falls and rigging failures.
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.
