Container Lifting Lug

These container lifting lugs are designed to fit into the side of the ISO corner boxes. Some are designed specifically for the side of the top corner box, some for the bottom corner box and others can be fitted in either. Their shape allows them to be fitted into the ISO corner box side slot. Once fitted they are usually attached to one leg of 2 leg sling. The lug is rotated in the ISO corner box to the angle of the sling and a spring loaded pin locks it in place, see below picture for a typical example.

Container lifting lugs are classified as lifting accessories and fall within the scope of The Supply of Machinery (Safety) Regulations 2008.

Storage and Handling.

It is recommended that wherever practicable, lifting lugs are not left in-situ, but should be removed after use and returned to proper storage. This storage area should be dry, free from injurious pollution and extremes of temperature.
