Standard Compliance: Most castings are manufactured to ISO 1161 standards, ensuring global compatibility with twist locks, cranes, and chassis.
Dimensions: The standard size is typically 178mm x 162mm x 118mm (approx. 7″ x 6.4″ x 4.6″).
Structural Variants: A full set of 8 pieces includes four distinct types: Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR).
Stacking and Locking: The top and bottom castings are designed differently to facilitate secure stacking. Top castings have a “shield” or “acorn” shaped side hole, while bottom castings often feature semicircular or stadium-shaped holes.
Lifting: They provide the reinforced points for crane spreaders or side-loaders to engage the container safely.
Installation: In new builds, they are typically welded to the container’s corner posts. For repairs or temporary structures, bolt-on versions may be used.
Durability: High-quality castings are tested for extreme temperature resistance (often down to -40°C) and high breaking strengths (up to 60 tons).
Applications Beyond Shipping
Modular Buildings: Used in container homes and portable offices for structural integrity.
Industrial Frames: Integrated into custom steel frames to allow them to be moved and stacked like standard containers.
Lifting Equipment: Used as connection points for specialized lifting rigs or caster wheel sets.
