Call the manufacturer Ask co-workers Look at the load capacity chart in the cab It’s best determined by lifting a load.
What’s the best way to find the load capacity of a crane?
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.
How do you calculate load capacity?
To determine the maximum load capacity of your deck, start by calculating its total area and multiply by 50 psf. So a 100 sqft deck would be designed to support 5000 lbs. Don’t get confused with what weight you might think or want to load the deck with.
What is the crane’s capacity based on?
The base formula for the Crane Capacity Index is:
At one radius the value of “Lifting height*Capacity” varies with different main boom lengths. At each radius the maximum value of “Lifting height*Capacity” is chosen.
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.
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.
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 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 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.

What is the load capacity?
Load capacity refers to the maximum demand, stress, or load that may be placed on a given system under normal or otherwise specified conditions for an extended period of time. In other words, it refers to the capacity of a system to continue to perform its intended function when supporting a specific amount of weight.
What is maximum load capacity?
Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration).
What is the standard floor load?
U.S. building codes specify a uniform live load of 40 pounds per square foot (psf) for most residential floor designs. This load is intended to account for the large number of loads that can occur in a residence. In reality, these loads do not typically take the form of uniform loads.
How do you read a load chart?
How To Read a Load Chart
- DIMENSIONS and WEIGHT — The chart shows the crane dimensions. …
- LIFT CAPACITY — This is where the magic happens. …
- LIFT RANGE — Just as important as lift capacity is lift range. …
- LIFT ANGLE — This chart illustrates the maximum lift if a luffing or fixed jib is used.
What must you know when using a load chart?
The load charts are specific to the make, model and configuration of a specific piece of equipment. Don’t forget to include adjustments for buckets, boom extensions, load blocks, hoisting rope and other attachments that will alter the lifting capacity of the crane or equipment used to perform the lift.
What affects the amount of weight a crane can lift?
For example, if the boom of the crane is extended to 250 feet and the radius (the distance from the center of the load to the center of the crane) is 180 feet, the max load weight drops considerably. The shorter the lift, the more weight can be handled. Transportation of the cranes also needs to be considered.
