Manufacturer profiles associated with Container Twistlock System.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rated load capacity is 30–50 tonnes per twistlock, as per ISO 1161. This exceeds the strength of the container corner casting. However, the exact capacity for a specific model must be confirmed with the legal manufacturer.
The system uses high-strength alloy steel, hardened steel components, and corrosion-resistant coatings. The material grade is cast steel ZG270-500 per GB/T 11352, with heat treatment. Surface treatment is hot-dip galvanized per ISO 1461.
The system uses hydraulic or pneumatic actuators to rotate twistlock cones 90 degrees within container corner castings. This creates a positive mechanical lock. Sensors verify proper locking status before lifting. Locking can be manual or automatic, depending on the model.
The operating temperature range is -40°C to 85°C. Below -40°C, there is a risk of steel brittleness. Always verify the specific temperature limits with the manufacturer for your application.
