Structural and functional composition: It is usually composed of three parts: dovetail groove, dovetail block and locking device, and is made of high-strength alloy steel or cast steel.

Working principle: By fitting the trapezoidal inclined plane structure (designed at 45° or 55°) with the matching base plate (welded to the deck or hatch cover), the container can be quickly fixed by rotating the locking device (such as the lever handle).

Core function: Prevent containers from shifting or overturning during jolts, especially suitable for fixing the lowest-level containers to the hull

Load-bearing capacity: The breaking load tension reaches 500kN, the shear force is 420kN, and the maximum pressure is 20,000kN.

Material and treatment: Cast steel shell, forged lock core, surface hot-dip galvanized or color-coated for rust prevention.

Specifications:  It is available in two angles of 45° and 55° to accommodate different bases

Modular Compatibility for Global Standards：Available in standard lengths: 220mm, 250mm, 280mm, 320mm (horizontal type), with customizable heights of 100-200mm (vertical type) to fit 20'/40'/45' containers, open-top units, and special flat-rack configurations. The universal dovetail interface seamlessly aligns with ISO container corner castings, ensuring quick installation and compatibility across all major logistics equipment.
