Suppose you have a crane with a load chart as follows (simplified example):
: This section provides details about the crane model, its maximum lifting capacity, and other relevant specifications.
| Boom Length (ft) | Radius (ft) | Max Load (lbs) | |------------------|-------------|---------------| | 50 | 20 | 10,000 | | 50 | 30 | 8,000 | | 60 | 20 | 12,000 | | 60 | 30 | 10,000 | load chart for crane
Leo looked at the chart. 11 tons at 55 feet was within the green zone—barely.
“You memorized the chart yet, rookie?” he asked, not looking at the young apprentice beside him. Suppose you have a crane with a load

Just then, the foreman’s voice crackled over the radio. “Marco, need you to lift the new generator. 11 tons, 55-foot radius. Chart says you’re good.” “You memorized the chart yet, rookie
: Some load charts divide lifting operations into zones based on the boom angle and radius. These zones help in determining the crane's lifting capacity more accurately.
Managers use them to determine if a specific crane model is suitable for a job before it ever arrives on-site.
The apprentice blinked. “What?”
: The load chart lists different boom lengths. The boom is the long, horizontal beam on the crane that can be extended or retracted. The chart provides load information for each boom length.
