Chain Blocks - Shipyard and Dry Dock Equipment
Manual chain blocks are portable hand-operated lifting devices used in shipyards, dry docks, engine rooms, workshops, and onboard maintenance. They provide controlled vertical lifting and positioning of machinery, valves, pipes, steelwork, and other loads where powered lifting equipment is unavailable or impractical.
ProShipWorks provides end-to-end support to source and supply Chain Blocks 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 | Applicable requirements may include EN 13157 for hand-powered cranes and ASME B30.21 for manually lever-operated or hand-chain lifting devices, depending on product type and market. Manufacturer test certificates, rated-load markings, and applicable national lifting-equipment regulations should be verified. |
|---|---|
| Class Approval | Chain blocks are generally supplied with manufacturer conformity and test documentation rather than type approval from a classification society. DNV, ABS, Lloyd's Register, Bureau Veritas, or ClassNK requirements may apply when the equipment is part of a classed vessel's lifting arrangement; acceptance depends on the installation and survey scope. |
Installation, Maintenance & Safety Information
| Installation Notes | Inspect the supporting beam, pad eye, trolley, or lifting point for adequate rated capacity and structural suitability. Install the block vertically, ensure the load chain is not twisted, and center the hook over the load. Carry out a pre-use inspection and use only certified lifting accessories. |
|---|---|
| Maintenance Tips | Inspect hooks, safety latches, load chain, hand chain, brake, gears, and casing before use. Lubricate the load chain with a suitable chain lubricant, keep the brake dry, and remove damaged or stretched components from service. Maintain periodic inspections and records according to manufacturer and vessel procedures. |
| Safety Notes | Never exceed the rated capacity or use a chain block for personnel lifting. Do not side-load hooks, shock-load the device, operate with a twisted chain, or stand beneath a suspended load. Isolate the lifting area and use trained personnel with appropriate PPE. |
