What this product does
Our corner castings are structural, weldable steel fittings that form the interface between a container and handling or securing devices, enabling lifting, lashing, horizontal joining, and vertical stacking through ISO‑standard apertures. They are supplied in four orientations—Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR)—to ensure correct engagement with twist locks, bridge clamps, spreaders, and chassis equipment at every corner of the container or fabricated module. Corner castings act as the housing for mechanical devices such as twist locks; they are non‑moving components engineered to withstand high loads and to maintain dimensional accuracy for safe intermodal operations.
Part numbers and orientations
- Part numbers: CHCCTL (Top Left), CHCCTR (Top Right), CHCCBL (Bottom Left), CHCCBR (Bottom Right), corresponding to standard ISO orientations for fabrication and maintenance.
- Identification: Markings and aperture geometry distinguish TL, TR, BL, and BR; correct placement is essential to preserve ISO engagement with handling gear and connection devices.
- Sets: Standard ISO containers use sets of eight castings (two per corner: one top and one bottom) to enable safe lifting, stacking, and securing in transport and static applications.
Standards and compatibility
- Interface: Designed for compatibility with ISO 1161 corner fitting apertures and face thickness requirements to allow engagement by twist locks, spreader heads, bridge clamps, and chassis pins.
- Guidance: Classification guidelines reference ISO 1161 and ISO 1496 for dimensional and strength requirements; manufacturing and welding procedures should follow approved specifications for the intended duty.
- System devices: Fully compatible with vertical double ended twist locks for stacking and with bridge clamps for horizontal joining, forming part of a complete container restraint system.
Technical data and drawings
- Drawings: Detailed dimensional drawings are available for fabrication and QA; request the latest revision drawing pack for TL, TR, BL, and BR.
- Typical dimensions and mass envelopes used in the industry support welding to container corner structures or fabricated frames; ensure conformance to ISO face thickness and aperture geometry during fabrication.
- Documentation: We provide drawings and catalogue references for project submittals and audits, aligned to the Shipping Container Connections catalogue.
Applications and use cases
- New builds and modular frames: Weld castings to steel frames to create ISO‑compatible interfaces for handling, transport, and site assembly of containerised modules and skids.
- Repairs and retrofits: Replace damaged corner blocks on existing containers to restore ISO interface integrity for twist lock engagement and lifting operations.
- System assemblies: Combine with double ended twist locks for vertical stacking and bridge fittings for side‑by‑side or end‑to‑end joining in compound layouts.
Installation and fabrication notes
- Welding: Castings are supplied ready for welding; maintain alignment, perpendicularity, and aperture tolerances to ISO 1161 requirements during fit‑up and weld out.
- Orientation: Observe TL, TR, BL, BR orientation and mirror relationships to ensure handling gear alignment; misorientation can impair engagement and safety.
- Inspection: After installation, verify face trueness and aperture dimensions; non‑conforming geometry can compromise twist lock seating and load transfer.
Safety and compliance
- Structural role: Corner castings transmit lifting, stacking, and restraint forces; use within an engineered load path compliant with ISO 1496 testing principles and site load restraint plans.
- Device integration: Safe operation depends on compatible twist locks and bridge clamps installed and inspected per manufacturer instructions and site procedures.
- Documentation: On request, we provide drawings and catalogue documentation to support approvals, maintenance records, and compliance submissions.
Delivery and availability
- National supply: We deliver corner castings Australia‑wide with discounted shipping to Sydney, Melbourne, Brisbane, Adelaide, Hobart, Perth, Canberra, and Darwin.
- Technical support: We support product selection, orientation checks, fabrication queries, and integration with twist locks, bridge clamps, and bolt plates for complete systems.
