Before making a purchase, make sure that your lifting sling has proper lifting points on the load. There should be a mechanism which allows your slings to be attached to the load.

Check that the holes are big enough to accommodate the entire weight of the load and prevent falls.http://www.z2-lifting.com/poly....ester-sling/webbing-
