Abstract: A cable protection device is designed to prevent a cable from being damaged by rubbing against a helicopter. A protection frame is installed-below a winch 11 connected to a helicopter. A supporting groove is formed on the protection frame, and a slide-contact body is rotatably fitted in the support groove. A part of the slide-contact body is exposed, and the cable hung down from the winch is brought into contact with the exposed portion. The slide contact body is divided into two or more parts, and it is formed by continuously aligning the divided slide-contact bodies of the cylindrical shape. Both ends of the divided slide-contact body are aligned by fitting the recession and the projection of the tapers of the ends of the adjacent divided slide-contact bodies to each other.

Abstract: PROBLEM TO BE SOLVED: To prevent a cable from being damaged by rubbing against a helicopter. SOLUTION: A protection frame 2 is installed on a side surface of a machine body below a winch 11 equipped with a helicopter 10. A supporting groove 213 of a circular cross section long in a horizontal direction is formed on the protection frame 2, and a slide-contact body 3 of a cylindrical shape is rotatably fitted in the support groove 213. A part of the peripheral surface of the slide-contact body 3 fitted from an opening part of the supporting groove 213 is exposed, and the cable 12 hung down from the winch 11 is brought into contact with the exposed portion. The slide contact body 3 is divided into two or more parts, and it is formed by continuously aligning the divided slide-contact bodies 30 of the cylindrical shape.
