What is the maximum weight the 30 ton capacity pedestal cranes shown in illustration D051DG can lift when married together in twin with the other pair of cranes at the opposite end of the hatch?

Correct Answer: Option B — 120 tons

Twin-crane operating modes permit two coupled pedestal cranes to combine their individual 30-ton capacities. When two pairs of twin cranes are married together across a hatch, the total safe working load reaches 120 tons under approved operational limits.
