Drawing 12-1 Medeia Crane Load Chart.pdf

This document is a Load Capacity Chart for an Alaska Marine Crane Model MCK-1240, provided by North Pacific Crane Company, LLC. The chart specifies the maximum lift capacity of the boom lift cylinders at various load radii and boom angles. At a 10-foot load radius with the boom at 76 degrees, the crane can lift 24,000 pounds, while capacity decreases as the load radius increases—reaching 2,610 pounds at a 40-foot radius with the boom at 0 degrees. The chart establishes baseline operational parameters for the crane's lifting capabilities and serves as a reference for safe equipment operation.

The chart includes critical operational warnings, noting that the rated load capacity is ultimately determined by the type of rigging used, meaning actual maximum lift capacity depends on the rigging equipment in use at the time of operation. The document explicitly states the crane is not suitable for personnel handling. This load chart appears to be a technical specification document that would be referenced in contract work involving marine or heavy lifting operations in Alaska, ensuring that contractors understand equipment limitations and operational constraints before submitting bids or proposals.
