ABSTRACT:
This apparatus is a tongs-like device for remotely scooping up cargo and personnel, comprising two identical elongated members pivoted at a selected distance from the device's top with a pivot pin. The lower portions are curved and vertical with cushions attached to their inner surfaces to enable the apparatus to hold either cargo or a person securely in place.
Each inner lower surface has an inflatable pillow with a perforated spongy cushion attached to it and removable for replacement. The cushions' perforations enable a snatched person to breathe easily, thus avoiding any possibility of suffocation, while being hoisted upwards by hoist equipment. A sturdy net is fastened to the shoulders of the lower portions and draped for the person to sit on. In another technique a pliable plastic sheet, having pie-shaped triangular cuts, allows a person to pass through in one direction but not in the reverse direction.
