Ship Cradle Rollers - Shipyard and Dry Dock Equipment
Ship cradle rollers are heavy-duty rolling assemblies used in shipyards and dry docks to support, move, launch, or dock vessels on engineered cradles. They are selected according to vessel weight, hull geometry, ground conditions, travel path, and required load distribution.
ProShipWorks provides end-to-end support to source and supply Ship Cradle Rollers for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Design and fabrication may follow applicable ISO 9001 quality systems, EN 1090 structural fabrication requirements, and local machinery, lifting, and occupational-safety regulations. Certification requirements are project- and jurisdiction-dependent. |
|---|---|
| Class Approval | Ship cradle roller systems are generally engineered and accepted on a project basis rather than covered by a universal class approval. DNV, ABS, Lloyd's Register, BV, or ClassNK may review the supporting structure, operating procedure, and load calculations when required by the vessel project. |
Installation, Maintenance & Safety Information
| Installation Notes | Install on a surveyed, level, and adequately load-rated foundation. Align rollers with the cradle and vessel centerline, verify load distribution, and perform controlled functional testing before vessel movement. |
|---|---|
| Maintenance Tips | Inspect rollers, shafts, bearings, welds, retaining devices, and foundations regularly. Lubricate bearings where specified, remove marine contaminants, check alignment, and replace damaged or excessively worn components. |
| Safety Notes | Use approved load calculations and an engineered movement plan. Keep personnel clear of pinch points and the vessel travel path. Do not exceed rated loads, operate on unstable foundations, or move a vessel without competent supervision and effective communication. |
