Abstract
In a self-propelled, remotely controlled vehicle adapted to operate on the sea bottom for extracting ores therefrom, a V-shaped tubular structure has at its apexes a system of crawlers for moving the structure on the sea bottom. Underneath each side of the V-shaped structure, a scraping system is operative and its long axis is perpendicular to the corresponding side of the V-shaped structure. Tubular conveying systems for elevating the ore to the surface are provided. The V-shaped structure is collapsible by means of hydraulic actuators.
