The MK-2 Container Lifting Lugs are lifting lugs for the vertical lifting of shipping containers. A set consists of four lugs, which are fitted from above into the four upper corner castings of the container. Together they have a working load limit (WLL) of 56 t at an angle of 0° to 15°.
45 mm eye diameter
During lifting, the weight is spread evenly across the four corners of the container. Each lifting lug has an eye with a diameter of 45 mm, which takes lifting chains and other lifting gear.
WLL of 4 × 14 t
Each lifting lug has a WLL of 14 t. With four lugs, this leaves ample margin for lifting fully loaded 20 ft and 40 ft containers. The WLL applies at an angle of 0° to 15° between the lifting lug and the lifting chain. At a larger angle, the lug is loaded at a different point and the working load decreases.
Fitting into corner castings
Corner castings are the corner fittings of a shipping container. Like the corner castings, the MK-2 Container Lifting Lugs are made to the ISO standard, so they fit precisely. Because the lugs sit on top, nothing protrudes at the sides. Containers can therefore stand close together or be lifted in tight spaces, such as on board a ship. Even when containers stand tightly side by side, the lugs can be fitted and removed from above.
Locking against release
Each lifting lug has a locking mechanism, which closes with a turning motion during fitting. This keeps the lug firmly in the corner casting while lifting. To remove it, the lock is opened by hand and the lug is turned out.
Lifting or stacking
Twistlocks and other container lashing equipment are designed for securing and stacking containers. The MK-2 Container Lifting Lugs are designed for lifting them.
