Do not insert the chain ring on the hook tip to shorten it and lift the load

All of the chain slings with more than one leg produce a horizontal component of force (see figure 5), which increases as the angle between the legs increases. If the hooks or any other fasteners have been inserted into a ring chain – for example, round a case or a drum –, the horizontal component of force is much bigger and, consequently, the angle of such legs should not exceed 30° to the vertical line.It should be emphasized that the load to shift should be capable of withstanding any horizontal components of force, while avoiding being damaged. The hook the chain sling has been fixed to should lie immediately above the centre of gravity.
