What is the lifting capacity of a hydraulic crane?

• A. 100 tons
• B. 350 tons
• C. 200 tons
• D. 150 tons

Answer: (D)

Lifting capacity is defined by the crane’s rated capacity, which comes from the manufacturer’s load chart and depends on the boom length, radius (how far the load is from the crane), outriggers, and overall configuration. For many hydraulic cranes used in structural collapse response, the commonly referenced capacity is 150 tons. This is the value you’d use in planning a lift when the crane is in its standard setup with outriggers deployed and a typical boom length. The actual safe lift can change if the radius increases, the boom is extended further, wind loads are a factor, or attachments alter the load path, so always consult the specific load chart for the exact configuration and conditions.
