How do you find the load chart of a crane?
The top row signifies the length of the boom. Looking at where these rows and columns meet, you’ll see two numbers in each cell. The first number is the crane’s load capacity for the given boom length and lift radius. In parentheses just below that number is the corresponding boom angle.
How much weight can a mobile crane lift?
It can lift up to 120 metric tons at the maximum radius of 100 meters. Cranes are also mainstays of global commerce: Without gantry quay cranes capable of hoisting from 40 to 80 metric tons, it would take weeks to unload the 20,000 standard-size steel containers that sit in one of today’s enormous container ships.
What is a cranes load capacity?
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. The 300 tonne-meter rating tells you the relationship.
What is load chart?

What is load chart capacity?
The capacities listed in a cranes load chart are not the actual loads that can be lifted on the hook. The values given in the charts are “Gross Capacities” or “Rated Capacities”. 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!

What is a load chart?
A crane’s load chart is the most important resource a crane operator should know for ensuring crane safety, and for determining what a particular crane is capable of lifting. With all of the different crane manufacturers out there, it is imperative that the crane’s load chart be well understood.
How do you calculate Crane capacity?
Divide the crane’s weight, measured in pounds, by 2. If the crane weight is 6,000 pounds: 6,000 / 2 = 3,000. Add the weight of the hoist and trolley, also measured in pounds. If they weigh 2,500 pounds combined: 3,000 + 2,500 = 5,500. Multiply the rated capacity load weight by the impact allowance factor.
What is Crane load?
Answer Wiki. The dynamic load with cranes can consist of a number of items. The wind blowing on the crane (boom, mast, etc.) is a dynamic load. The action of swinging a load consists of dynamic forces.
