It is used to secure containers on board vessels during sea transport. These systems prevent container movement caused by wind, waves, and vessel motion, ensuring cargo safety, vessel stability, and compliance with international maritime regulations.
Containers are exposed to significant dynamic forces during sea transport, including rolling, pitching, and vertical accelerations. Without proper lashing, containers may shift, collapse, or be lost overboard, posing serious safety and environmental risks.
Container lashing equipment connects containers to the vessel structure and to each other, forming a secure load path that transfers forces safely into the ship. Depending on the vessel type and stacking configuration, different lashing components are combined to achieve the required securing strength. Typical container lashing systems may include twistlocks, lashing rods, turnbuckles, stacking cones, and foundation fittings, selected according to vessel design and operational conditions.
These securing principles form the basis of modern container lashing systems used on board container vessels.

Every product is designed to withstand the demanding loads of marine transport and align with international securing standards.
Lashing is required to maintain container stack stability, protect cargo, and ensure vessel safety under dynamic sea conditions.
Lashing requirements depend on vessel type, container stack height, voyage conditions, and applicable maritime regulations.
Container lashing equipment consists of mechanical components used to secure containers on board vessels, preventing movement during maritime transport.
The CONTECH® T‑1 intermediate twistlock is a durable manual locking device designed to securely connect stacked containers. It ensures reliable vertical alignment, high stability, and safe handling during maritime, inland, and terminal operations. Built for compatibility with ISO corner castings, the T‑1 offers strong performance, long service life, and dependable container‑stacking safety.
The CONTECH® LE‑31 single lashing plate is a high‑strength lashing point designed for secure container fastening on vessel decks and terminal platforms. Installed directly on the deck structure, it provides a reliable anchor for lashing rods, turnbuckles, and other container securing systems. Engineered for durability and compatibility, the LE‑31 integrates seamlessly with CONTECH® lashing components, supporting safe, stable, and efficient container securing operations.
The CONTECH® S‑32B turnbuckle is a heavy‑duty lashing component engineered for securing and tensioning container stacks on board vessels. Designed for reliable performance in demanding marine environments, it connects the ship’s lashing eyes with vertical or diagonal lashing rods to ensure safe and stable container tiers during sea transport. Compatible with CONTECH® lashing rods LR‑63 (knob type) and LR‑65 vertical rods, the S‑32B supports multiple lashing configurations depending on vessel layout and stack height. Its robust construction, long service life, and seamless integration with standard container‑securing systems make it an essential part of any professional lashing arrangement.
The CONTECH® LR‑63 knob lashing rod is a high‑strength diagonal lashing bar designed to secure container stacks on board seagoing vessels. It engages in the front holes of the ISO corner castings and is extended to the required length using the CONTECH® S‑32B turnbuckle with jaw, forming a reliable connection between the container and the vessel’s lashing system. Manufactured from forged, quenched, and tempered 42CrMo steel components, the LR‑63 delivers exceptional durability and high breaking‑load performance. The swivel‑head design ensures smooth alignment during tightening, reducing handling effort and improving safety during lashing operations. LR‑63 rods are available in multiple lengths—1900, 2450, 4700, and 4950 mm—to suit different vessel configurations and stack heights.
