FIELD: mining.
SUBSTANCE: invention relates to mining, particularly, to devices of underwater production of solid minerals. Device can be used also for geological survey data, gasket of gas and oil pipelines, development of peat deposits. Legged device comprises a leg, supports, telescopic strings, working member, control system. At that, the support is movably connected with a rotary platform equipped with a plug, by means of rollers, articulated with the leg, with possibility to turn it relative to the axis of the plug. Herewith, the leg is equipped with a counterbalance to the drum, covered with a flexible element by one complete revolution, for example, a rope, rigidly fixed on the left and on the right ends of the leg.
EFFECT: technical result consists in efficiency improvement of production and improvement of stability when walking.
