Overview

EN 14874:2005 - "Inland navigation vessels - Studless anchor chain - Cable lifter" is a CEN standard that specifies requirements for cable lifters (sprocket wheels) intended for use with round steel link (studless) anchor chains manufactured to EN 14330. The standard covers design intent, dimensions, materials, designation, marking and testing for cable lifters used on inland navigation vessels. It ensures safe, reliable engagement between chain and cable lifter during anchoring operations.

Key topics and requirements

• Scope: Applies to cable lifters for round steel link chains according to EN 14330; not intended for passage of certain accessories (e.g., Kenter-type joining shackles per EN 14606).
• Material: Grey cast iron, grade EN‑GJL 200 in accordance with EN 1561. Material testing follows EN 1561 requirements.
• Minimum teeth: Cable lifters must have at least five teeth.
• Operational safety: Design must prevent the chain from springing out or sliding; safe lifting/lowering requires an angle of contact α ≥ 110° and more than two teeth engaged (reference EN 13711).
• Dimensions and tolerances: Dimensions are defined in Table 1 and calculated using the formulas in Annex A (reference diameter D0, groove base diameter d3, groove width b, supporting diameter d4, external diameter d1, external width c, pocket length w, pocket radii r1/r2). General tolerances: ISO 8062‑CT12 for castings and ISO 2768‑1 class m for mechanical finishing.
• Designation and marking: Example designation - Cable lifter EN 14874 – 13 × 36 – 9. Marking must include the standard number (EN 14874), chain nominal size (d × p), manufacturer’s mark, traceable serial number and date of manufacture.

Applications and who uses it

EN 14874 is used by:

• Shipbuilders and naval architects designing anchor handling and windlass systems for inland navigation vessels
• Marine equipment manufacturers and foundries producing cable lifters and cast components
• Shipyards, procurement and maintenance teams specifying replacement parts and ensuring interchangeability
• Classification societies and regulatory authorities verifying compliance with equipment standards
  Practical applications include specification and manufacture of cable lifters for windlasses, capstans and chain handling equipment to ensure safe anchoring and correct chain-to-sprocket engagement.
