SI-7F

SELF HANGING STACKER WITHOUT FLANGE

SI-7F Self-hanging stacker without wings

The CONTECH® SI‑7F self‑hanging stacker is designed to safely absorb and transfer the horizontal shearing forces that occur between stacked containers during vessel loading, transport, and unloading. It is primarily used in 20 ft container configurations positioned within cell guides, where precise vertical alignment and secure interlocking are essential.

Unlike traditional stackers equipped with wings, the SI‑7F features a streamlined, wingless design, allowing the two adjacent containers to rest flush against the corner castings. This improves vertical load transfer and ensures optimal fit within tight cell-guided spaces.

The SI‑7F provides robust lateral restraint, minimizing container movement caused by vessel motion, swell, or dynamic forces at sea.

Key characteristics include:

• Wingless profile, ideal for use where containers must sit tight together inside cell guides
• Self‑hanging mechanism for quick and safe installation
• High shear‑force resistance, ensuring alignment and stability of 20ft containers
• Durable, marine‑grade construction, engineered for repeated handling in harsh port conditions
• Compatible with standard ISO corner castings

This configuration is particularly well suited for container stacks on feeder vessels and other applications where space constraints and operational speed are critical.
