Question: To increase the lifting capacity of a mobile crane at a given radius, what action related to counterweights is typically taken?
Answer options: ✅ Adding more counterweights.
- Removing some counterweights.
- Adjusting the boom length.
- Increasing the hoist line reeving.
Correct answer: Adding more counterweights.
Explanation: Adding more counterweights increases the crane's stability and counterbalancing effect, thereby increasing its lifting capacity at a given radius. Removing counterweights would decrease capacity, while boom length and reeving affect capacity differently but are not directly related to counterweight quantity for stability.
