Abstract
An apparatus for evaluating the condition of a lift sling. The apparatus includes a body with an upper section and a lower section. The lower section includes a cradle member with a load bearing surface that engages an inner surface of a connecting link at one end of a sling. The apparatus includes an engagement section that receives and positions the end of a measuring device so that it is in tangential alignment with the load bearing surface of the cradle member. In use, one end of a sling is positioned on the load bearing surface of the cradle member and one end of a measuring device is positioned on the engagement section of the apparatus. The apparatus is then raised so that the sling and the measuring device are hanging freely. The reach of the sling is then measuring using the measuring device.
