Chain Tension Lever for Container & Ro-Ro Lashing

Chain Tension Lever CB-B1

— Heavy duty chain tension lever for container and Ro-Ro cargo securing —

Product Overview

Chain Tension Lever (Chain Tensioner / Tensioning Rod) is a mechanical tensioning device for container and Ro-Ro cargo lashing systems. Utilizing the principle of lever force amplification, this product rapidly and reliably applies pre-tension to lashing chains, ensuring cargo stability and safety during ocean shipping, roll-on/roll-off transport, and heavy equipment transportation.

As a portable tensioning tool within container lashing systems, it is typically used in conjunction with lashing chains, hooks, and container D-rings to achieve controlled, repeatable chain tensioning results.

OLIPORTS Chain Tensioners undergo strict dimensional accuracy and material quality control during manufacturing. Their design is based on extensive port and vessel application experience, and complete technical drawings are available for engineering verification.

FAQ

Can a chain tension lever be used alone without a lashing chain?

No. Chain tensioners are tensioning devices and must be used in conjunction with lashing chains, hooks, and container D-rings as lashing points. They do not possess the capability to independently secure cargo.

What types of cargo are suitable for chain tension levers?

This tension lever is widely used for securing vehicles on Ro-Ro vessels, heavy machinery, project cargo, and general containerized cargo requiring chain fastening.

How does a chain tension lever differ from a turnbuckle or ratchet device?

This chain tension lever achieve rapid tensioning and release through lever-assisted force amplification; turnbuckles rely on threaded adjustment, resulting in relatively slower operation; ratchet mechanisms are primarily used for webbing rather than chains. In heavy-duty and marine environments, chain tensioners are more commonly employed.

What chain sizes are compatible with this chain tension lever?

The chain tension lever can be supplied to match different lashing chain sizes. Compatibility depends on the hook and chain connection configuration. Please confirm chain diameter and working load when ordering.

Is the chain tension lever compliant with cargo securing practices?

The chain tension lever is designed for use in standard container and Ro-Ro cargo securing systems and aligns with commonly accepted cargo securing practices in marine transportation. Compliance confirmation can be supported with technical documentation.

Are customized dimensions or configurations available?

Customization available. Dimensions, connection methods, and surface treatments can be adjusted according to project requirements and operating conditions.
