Modular 20/40FT Container Top Safety Cage – Elevating Maritime Safety Standards

At ZHM Metal Engineering Co., Ltd., we understand that safety is the cornerstone of maritime and port operations. We are proud to introduce our state-of-the-art 20/40FT Modular Unit Container Top Safety Cage, a premium solution designed to safely transport lashing personnel from ground level to the top of container vessels.

Engineered for versatility and rugged durability, this system allows crews to work securely within the confined protection of the cage, significantly reducing the risks associated with high-altitude vessel operations.

Key Features & Modular Design

Our safety cage features a revolutionary modular lift design, offering unparalleled flexibility for diverse operational requirements.

Detachable 20FT Module: The system is equipped with specialized cell guides that allow for the rapid insertion, operation, and replacement of the 20ft cage within the 40ft structure. This enables operators to switch between individual 20ft or 40ft configurations effortlessly based on the vessel size and job scope.

ISO Standard Compatibility: Designed to be lifted by crane spreaders at ISO-standard 20ft and 40ft twistlock centers, our cages are universally compatible with almost all types of port cranes, ship-to-shore gantries, and vessel equipment.

Comprehensive Safety & Compliance

Safety is not an option; it is a necessity. Our personnel basket is built to exceed stringent international safety standards, ensuring full compliance with EU statutory regulations.

360-Degree Protection: The working area is fully enclosed with robust hand-railing installed on all sides.
Fall & Object Protection: The perimeter is secured with steel mesh boundaries and kick plates to prevent tools or materials from falling. The entire working surface utilizes heavy-duty anti-slip floor plates, providing secure footing even in wet maritime conditions.

Redundant Lifting Security: Beyond the conventional spreader twistlock attachment, the cage is installed with mandatory certified secondary attachment slings. These are equipped with screw-pin bow shackles to "lock" onto the crane spreader, providing a critical layer of redundancy for personnel safety during the lift.

Technical Specifications & Applications

Primary Application: Safe transfer of lashing personnel to container vessel tops.
Structure: High-tensile steel modular frame with cell guide integration.
Lifting Mechanism: ISO Twistlock compatible + Secondary sling safety lock.
Flooring: Industrial-grade anti-slip chequer plate with drainage.
Safety Barriers: Steel mesh infill with reinforced toe boards (kick plates).
