The distance is measured from the center pin of the crane to the center of the load. Once you determine the distance, look on that line for the largest capacity; that will indicate how many feet of boom must be extended. In this case, it is 45 feet.
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 do you measure a crane?
Tips On Choosing the Right Size Crane
- Calculate the maximum radius from the center of pin.
- Confirm the total weight of the load. …
- Determine clearance issues, either height under ceiling or overhead obstructions.
- Allow for the height of obstructions between crane and load.
- Consider the hook height required with lifting equipment.

What is crane boom angle?
The boom angle on lattice boom cranes is the angle between the center line of the boom (from the boom butt pins to the boom tip sheave) and the horizontal while the boom is under load (fig. … The boom angle indicator is a quick reference for the operator to know what angle the boom is at.
How are crane lift plans calculated?
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 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 far can a mobile 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 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 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 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 is crane boom lifting capacity 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.

What is a boom angle indicator?
Boom angle indicators are normally mounted on the back side of a boom where they can easily be read by the operator. They are used as a quick reference for the operator to know what angle the boom is at. Boom angle indicators are designed to improve the boom operator’s ability to detect tip over situations.
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.
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 weight 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.
