FIELD: dredgers and soil-shifting machines, particularly drives for building, road-building and hoisting machines provided with hydraulic drives and subjected to great loads applied to executive tools.
SUBSTANCE: hydroficated drive has power hydraulic cylinder with rod end and piston end connected to hydraulic system of earth-shifting machine. Power cylinder is installed on handle and has body to be rigidly fixed in any point thereof. Hydraulic cylinder used for bucket rotation is made as double-acting hydraulic cylinder with double-acting rod having ears to be hinged with the bucket in points of its fixation. Longitudinal axis of hydraulic cylinder and bucket fixation points are arranged on closed circle. Circle perimeter is equal to two rod travels and length of arch between bucket supports.
EFFECT: extended range of bucket rotation angle and simplified structure thereof.
