Question: A crane's load chart indicates a capacity of 25,000 kg 'Over Rear' with a 30-metre boom at an 8-metre radius. For the same boom length and radius, the 'Over Side' capacity is 20,000 kg. If the operator needs to perform a lift requiring continuous slewing from 'Over Rear' into the 'Over Side' quadrant, what is the maximum gross weight (including deductions) that can be lifted?
Answer options: ✅ 20,000 kg
- 25,000 kg
- 22,500 kg
- 18,000 kg
Correct answer: 20,000 kg
Explanation: When slewing across different quadrants, the operator must adhere to the most restrictive capacity for any quadrant through which the boom will pass. In this scenario, the 'Over Side' capacity of 20,000 kg is the limiting factor, meaning the total gross weight of the load plus deductions cannot exceed this value for the entire operation.
