The load chart of a crane enables the operator to combine the load radius with boom length to determine the __________.

🔍 Key Concepts

• Crane load chart purpose and what information it provides • Relationship between load radius, boom length, and safe lifting capacity • Difference between structural/ stability limits and machinery (rope, engine, counterweight) sizing

💭 Think About

• Ask yourself: When an operator looks at a load chart during a lift, what decision are they mainly trying to make before picking up the load? • Which of the choices is directly limited by radius and boom length, and must stay within a maximum safe value to avoid tipping or structural failure? • Which items (rope strength, counterweight, horsepower) are usually fixed by design, versus the one that changes with every lift based on boom angle and radius?

✅ Before You Answer

• Verify which chart values change as radius increases and boom length changes during a lift. • Check which choice is normally printed in table form on a crane’s capacity chart for each combination of radius and boom length. • Make sure you distinguish between what the manufacturer pre-engineers (rope size, counterweight, engine) and what the operator must constantly look up for each lift.
