Question: Why is it critical to ensure the correct counterweight configuration is installed according to the crane's load chart for specific lifting operations?
Answer options:
- To optimize fuel efficiency during the lift. ✅ To ensure the crane remains stable and does not tip over when lifting the planned load.
- To reduce wear and tear on the swing bearing.
- To allow faster swing speeds without affecting load swing.
Correct answer: To ensure the crane remains stable and does not tip over when lifting the planned load.
Explanation: The counterweight system is a fundamental component of a crane's stability. Incorrect counterweight - too little or too much - can compromise stability, leading to overturning, or overstressing the crane structure. Matching the counterweight to the load chart is crucial for safe operation, as per CSA Z150 Clause 4.1.3.
