20/40FT Modular Container Top Safety Cage | ISO Standard Crane Lifting Safety Cage

20/40FT Modular Unit Container Top Safety Cage is a professional marine safety lifting solution independently designed, manufactured, installed and commissioned by ZHM Metal Engineering Co.,Ltd. Tailored for container vessel stevedoring, lashing and marine lifting operations, this modular safety cage complies with international marine safety standards and EU statutory regulations, providing fully enclosed, high-security working environments for offshore and port lashing personnel.

Built with ISO standard twistlock centres for 20ft and 40ft container specifications, our modular container safety cage is fully compatible with mainstream crane spreaders, port cranes and container vessels worldwide. The standardized lifting structure realizes precise docking and stable hoisting, eliminating equipment adaptation barriers for global port and marine engineering operations. Different from traditional integrated safety cages, our innovative modular lift design features an easily detachable 20ft cage module, supporting flexible independent use of 20FT single cage or combined 40FT integral cage according to on-site operational demands, greatly improving the flexibility and efficiency of container top working.

To optimize on-site assembly and replacement efficiency, the safety cage is equipped with professional cell guides, which enable rapid positioning, installation and disassembly of the 20ft cage inside the 40ft modular structure. This structural design effectively shortens equipment replacement downtime, accelerates overall port operation progress, and adapts to high-frequency and high-intensity container stevedoring work scenarios in modern ports.

In terms of safety configuration, this marine safety cage strictly follows EU statutory safety norms. Full-circle safety hand-railing is installed on all inner sides of the cage to prevent personnel falling risks during high-altitude operations. The entire working area adopts multi-layer safety protection systems, including anti-slip floor plates, high-strength steel mesh boundaries and sturdy kick plates. The all-round protective structure not only ensures stable standing of operating personnel but also effectively blocks falling objects from the upper space, realizing omnidirectional safety protection for high-altitude container top work.

For extreme working condition safety redundancy, our container top safety cage is equipped with certified secondary attachment slings and screw-pin bow shackles. On the basis of conventionalspreader twistlock attachment, the auxiliary locking structure can firmly fix the cage on the crane spreader, avoiding accidental separation and shaking during lifting, and maximizing the personal safety of lashing staff working at height.

As a professional marine metal engineering manufacturer, ZHM Metal Engineering Co.,Ltd. strictly controls every link of product design, raw material selection, production processing, precision welding, on-site installation and commissioning. All modular safety cages pass strict quality and safety tests, featuring high structural strength, strong corrosion resistance, stable lifting performance and long service life. Our products are widely applicable to container vessel lashing, port container top maintenance, offshore marine engineering, freight terminal lifting operations and other scenarios, providing reliable standardized safety equipment for global marine and port industries.
