Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
119 words
A handling system for boats and the like comprising: suspension means including hoist means and beam means defining laterally spaced sites for sling attachment; sling means including a plurality of pliant sling sections having end portions connected to said sites whereby to form a support loop and further having joinable intermediate portions; and pin assembly means releasably connecting said sling sections at said intermediate portions, said pin assembly means including sling section connecting pin means having a bore in one end thereof and pivot means to rotatably attach a safety link on the other end, a safety link swingably attached to said other end, and fastener pin means insertable through said bore to lock said safety link in position.
