Weldable Cone AJ-A1
— Engineered Base for Reliable Container Deck Connections —
The Weldable Cone is a steel-based fitting designed for welded installation, featuring a stable triangular symmetric structure. This product is typically directly welded onto ship decks, base foundations, or platform structures, serving as an embedded mounting point for other container locking devices such as stacking cones and fixed locks.
OLIPORTS weldable cones are usually made of high-strength cast steel or forged steel, boasting excellent weldability and corrosion resistance, meet the strength and impact test standards of classification societies.

Drawings and Features of Weldable Cone

Key Features
Note: The welds shall comply with the regulations of international classification societies or industry standards to ensure tensile and shear resistance.
- Enhances stacking safety and prevents shifting or misalignment
- Precise Positioning: The concave design in the middle allows for accurate embedding of stacking cones or bolts, ensuring firm alignment of the locking devices.
- Simple Structure: Boasting a smooth appearance and reinforced edges, it facilitates welding operations and is not prone to water accumulation.
- Class-certified by ABS, DNV, CCS, etc.
Applications
Welding Installation: Weld directly onto the surface of steel structures to ensure firmness and load-bearing performance.
Deck of Container Ships
On container ships, Weldable Cones are welded onto the deck’s steel structures, serving as mounting bases for stacking cones or twist locks.
Foundation Platforms of Port Container Yards
Welded and installed on supporting beams or steel frames, they coordinate with container guides for positioning, enabling stacked containers to land more quickly and safely, thus improving the efficiency of hoisting operations.
Connection Bases for Offshore Modular Devices
In modular steel structures such as offshore wind power platforms and oil drilling platforms, Weldable Cones can act as positioning points for transport modules, ensuring docking accuracy and fixing strength during module transportation and installation.
Ro-Ro Ships or Vehicle Transport Platforms
Used as receiving bases for detachable locks. Especially in scenarios requiring frequent loading and unloading, stacking cones can be quickly inserted into the cone sleeves to complete loading and fixing operations.
Custom Container Equipment and Frame Structures
On non-standard containers, flat rack containers, or equipment transport brackets, Weldable Cones can be flexibly arranged and welded at different positions according to structural design requirements, for matching and installing devices such as corner locks and stacking connectors.
