Massachusetts Hoisting License Practice Test

What happens to equipment capacity when the boom is lowered?

1. It increases

2. It remains the same

3. It decreases

4. It fluctuates

The correct answer is: It decreases

When the boom is lowered, the capacity of the equipment decreases due to the change in the lift's angle and leverage. This decrease in capacity occurs because lowering the boom effectively shifts the center of gravity and alters the load distribution. As the boom is brought closer to the ground, the ability to maintain stability and lift heavy loads is reduced. At lower angles, the lifting mechanism does not have the same mechanical advantage, which limits the weight it can safely carry. It's essential for operators to understand this relationship between boom position and equipment capacity to ensure safe and effective hoisting operations.
