Container Lashing Systems

• Area: Locking mechanism failure / stiff rotation
  Check: Manual twistlocks: manually rotate head through full 90° range, verify positive lock without slipping. Automatic twistlocks (C8A, Hippo): verify lock engages on crane lift and releases smoothly on lowering. Document any binding or delayed engagement.
• Area: Visible wear, plastic deformation, hairline cracks
  Check: Visual inspection: examine head and shank for cracks (reject any visible deformation), bent levers, missing retaining pins, cam surface pitting. Dimensional check: use go/no-go gauges on cam width, body diameter, lug protrusion; reject if drift >0.3 mm. 3D scanning for close-tolerance FAT systems.
• Area: Rust, salt deposits, corrosion on all surfaces
  Check: Check for white rust, galvanic corrosion (zinc loss), crevice corrosion at joints. Clean all parts from dirt, rust, salt deposits including bolts/nuts. Inspect galvanized coating for pitting. Measure coating thickness if severe corrosion suspected. Turnbuckles must not be corroded or too tight.
• Area: Corner casting fit & positive locking safeguard
  Check: Ensure bottom container corner castings are clean and free of deformation (damaged castings prevent proper lock seating). For C8A with 'positive locking' feature: verify lock can be manually locked below lashing bar level to limit peak forces on lashing bars and turnbuckles, preventing overload damage.
• Area: Valid certification & compliance documentation
  Check: Verify each twistlock, lashing rod, turnbuckle, and plate has current valid certification (DNV, BV, KR, ABS, or LR approval). Confirm equipment meets ISO 1496-1, ISO 3874, ISO 17040, and SOLAS VI/5 requirements. Reject any uncertified or expired equipment. Maintain inspection records per IACS UR C7.
• Area: Lubrication & maintenance deficiencies
  Check: Automatic units (Hippo, C8A): verify maintenance-free design requires no greasing. Manual/semi-automatic: check all moving parts are lubricated, springs function correctly, wire-operated drop-lock mechanisms (Hippo) operate smoothly. Document any seizing or stiffness; apply appropriate lubricant if needed.
