What load ratings apply to your double ended twist locks?
Our double ended twist locks are documented to a minimum breaking load of 500 kN in tension, with typical shear performance of 420 kN when used with ISO corner castings under appropriate design assumptions; test reports and drawings are available on request.
Are these twist locks compatible with ISO 1161 corner castings?
Yes, the product is intended for use with ISO 1161 corner castings; performance and fitment rely on ISO‑compliant dimensions and container condition, and engineered load paths per application are required.
Should we choose manual, semi‑automatic, or fully automatic locks?
Manual double ended twist locks offer simplicity, robustness, and cost efficiency where supervised engagement is acceptable; semi‑automatic and fully automatic devices improve throughput and reduce work at height but involve higher cost and mechanism complexity; selection should follow a task‑based risk assessment and operational requirements.
How many units are required to stack one container on another?
Four units are used per container interface—one at each corner—to achieve a secure vertical connection, observing correct left/right locking orientation per corner casting positions.
Can these be used with bridge clamps for multi‑container assemblies?
Yes, combine vertical double ended twist locks with rated bridge fittings for horizontal restraint across adjacent containers to mitigate lateral movement in compound assemblies.
What documentation is supplied for compliance?
We can provide drawings, operating instructions, shear factor‑of‑safety documentation, displacement and stress‑at‑failure test data, and catalogue references to support engineering approval and audit requirements.
What surface protection do the units have?
Units are hot‑dip galvanised for enhanced corrosion resistance in marine and industrial environments, supporting long service life with appropriate inspection and care.
