Container are supplied, and used, in sets of 4. They have a total lifting capacity of up to 56 ton. The CLB and CLT Container Lifting Lugs serve as flexible lashing points for the transportation of containers. Two types are available dependent upon where you want to fasten them; to the side or the top of the container. The CLB model is mounted horizontally to the side of the container at either the top or the bottom fixing holes. This model has a spring-loaded bolt to prevent accidental release. The CLT type is vertically mounted in the hole at the top of the container and is locked into place by simply turning the lug 90 degrees. This configuration allows for transportation via the use of a lifting frame in conjunction with cables, chains or slings. NB. NOT TO BE USED ON A 4 LEG CHAIN SLING.
