Product Overview.

The Container Operation Emergency Tool is a manual unlocking device specifically designed for semi-automatic single-line twistlocks. When a twistlock cannot be released normally due to wire damage, mechanical jamming, corrosion, or unexpected operational conditions, this tool serves as a safety emergency measure to achieve forced release.

Leveraging OLIPORTS’ extensive experience in container lashing and securing systems, this emergency tool was designed with the practical requirements of port terminals, container vessels, rail yards, and multimodal logistics centers in mind. We maintained close communication with end-users to ensure compatibility with mainstream semi-automatic twistlock structures and ISO standard container corner fittings.

Manufactured under a rigorous quality control system, the emergency tool features a high-strength steel working end and a non-slip rubber handle, balancing durability with operational safety. It delivers stable performance in high-load, highly corrosive port and marine environments. Each unit undergoes inspection to meet the reliability demands of professional container securing operations.

As a specialized supplier of container securing equipment, OLIPORTS not only provide the emergency tools themselves but also offer product selection support, technical advice, and bulk supply solutions. This helps customers mitigate operational risks caused by equipment failure and enhances overall operational safety.

• Enables manual emergency unlocking when automatic mechanisms fail
• Weldable & Class Approved: Meets ABS, DNV-GL, CCS, and ISO standards

Why You Need an Emergency Tool

During actual container operations, twistlocks may fail to unlock properly due to the following reasons:

• Broken or failed operating wires
• Uneven force distribution causing lock jamming
• Corrosion caused by marine environments
• Emergency situations or container deformation

The absence of emergency tools prevents container removal, leading to operational disruptions, safety hazards, and financial losses. The Emergency Tool enables manual unlocking directly through the container corner fittings, ensuring uninterrupted operations.

How It Works

Insert the emergency tool into the side hole of the ISO container corner fitting. By applying appropriate manual force, directly trigger the internal unlocking mechanism of the twistlock. This enables safe release of the container even when the normal operating wire fails.

Application

Deck Container Operations: Release jammed semi-automatic twist locks that cannot be opened normally due to pressure, deformation, or corrosion.

Emergency Safety Procedure: Ensure continuous container release capability as a critical backup tool for compliance with safety protocols.

Port & Terminal Maintenance: Used by inspection and maintenance crews to safely manipulate twistlocks during checks or repairs.
