ABSTRACT:
A sling system is disclosed for suspension from a helicopter with the system including a remotely actuable hook assembly from one hook of which the ends of the loaded sling lines may be released permitting sling separation from the cargo without manual effort. A guide includes ring-like retainers through which the sling lines pass after passage about the load. A tag line between the cargo hook assembly and the guide permits lifting of the guide during load separation resulting in downward passage of the load biased sling lines therepast and ultimately retraction of the sling lines from about the load. Another hook component of the hook assembly is also remotely actuable to release the tag line, the guide and unloaded sling lines carried thereby at a sling rewinding site whereat the guide is mounted within a winding mechanism facilitating winding of the lines about the guide. A holder for the guide is also disclosed permitting guide rotation during paying out of the sling and tag lines.
