ABSTRACT:
A self releasing sling hoist is disclosed that includes a body for connecting to a hoist line for lifting a load. A sling such as a flexible line or cable has one end attached to one side of the body. The other end is provided with a loop or opening for attaching to a hook connected to the other side of the body after the sling has been passed under or otherwise arranged to support a load. A releasing arm is connected to the body to pivot toward the hook under the influence of the load as the weight of the load is transferred from the sling and the body is lowered toward the load. Continued downward movement of the body relative to the load will cause the release arm to pivot past the hook and force the end of the sling off the hook thereby automatically releasing the sling from the load.
