The stitches of the slings should never be placed on the hooks or on any other lifting devices. While
lifting any load, the stitches should always work on the straight part of the sling.
The load should be so secured by the sling as not to overturn while being lifted. The sling should be so
placed that the lifting point lies just above the centre of gravity and the load is balanced and firm. If
these conditions are not satisfied, the sling might move and produce heat through friction.
Whenever a U-shaped sling is used, the load should be well secured and firm, because there is no grip,
unlike the choke hitch system, and the sling may roll through the lifting point.
As for slings used in pairs, it is recommended that a rocker arm be used, so that the arms of the sling
can be suspended as vertically as possible and the load can be equally distributed between the arms.
When the sling is used with a choke hitch, it should be so positioned as to form a natural angle of 120°
and avoid producing heat through friction.
The websling should never be forced into position, nor should hold be increased. Fig. 6 shows how to
correctly secure a load in a websling used with a double choke hitch, which results in enhanced safety
and helps prevent the load from sliding through the sling.
