STS Crane Size Configurator
Explore how crane reach, lift height, and vessel geometry fit together.
Engineering considerations
Vessel trim and list are not included in this geometric model. Additional outreach and lift-height allowances may be required to accommodate vessel attitude and operating conditions. Verify all dimensions and clearances against project-specific requirements.
Ship-to-shore crane outreach and lift height planning
This STS crane size calculator compares selected crane outreach and container crane lift height with illustrative vessel and berth geometry. Use it for preliminary crane sizing for container vessels and terminal layout studies.
Required outreach is measured from the waterside rail to the farthest container-row center. It includes rail setback, the ship-to-quay gap, and the centered container bank within the modeled vessel beam. Required lift height is the stack top above rail elevation plus one lifted container height; it depends on moulded depth, draft, water level, and on-deck tiers. Reserves are selected crane dimensions minus these geometric requirements. Negative reserves indicate a geometric shortfall.
Common planning questions
How can I compare crane outreach for 24-row and 26-row vessels?
Select Megamax-24 or Future Ultra-Large (26 Rows), then review required outreach, outreach reserve, and rows within reach. Both presets are illustrative; the 26-row option is a conceptual future-planning scenario, not a verified vessel design. Row pitch and berth offsets also affect outreach.
How do berth conditions affect container crane lift height?
Higher water levels raise the vessel relative to the rails, while greater draft lowers the modeled deck. More on-deck tiers or taller containers increase required lift height. Compare scenarios using the vessel and berth controls.
Does a positive reserve establish crane suitability?
No. This preliminary geometric model does not verify lifting capacity, structural strength, vessel stability, collision envelopes, or operating limits. Detailed suitability assessment requires vessel-specific and project-specific checks, including trim, list, and appropriate operating allowances.
