Easy Installation: The installation and removal process is simple and efficient. To disengage a container, just rotate the handle to the unlock position. Strength: Secure working load of 250 kN and maximum breaking load of 500 kN provide reliable performance under extreme pressure and impact during stacking and transit. Effortless Operations: Manual design with left and right hand rotation options for easy use. Rotate the handle to lock or unlock containers quickly and with minimal effort. Material: Constructed from carbon steel for rust resistance and durability in harsh transport environments. Use scenario 1: In warehouse stacking and retrieval, facilitating quick and safe engagement and disengagement of containers to improve workflow efficiency. Use scenario 2: During intermodal transport on trucks, ships, or rails, providing strong load handling and fast operation to secure containers during shifting or repositioning. Use scenario 3: In outdoor or harsh environments, where rust resistance and durability of carbon steel contribute to long service life and reliable performance.
