The invention relates to a self-stabilizing type hydraulic supporting device which comprises a moving rack and four self-stabilizing branched chains. The self-stabilizing branched chains are symmetrically installed on the two sides of the moving rack through bolts; the moving rack comprises a fixing platform, an installation platform, two T-shaped sliding grooves, two T-shaped sliding rails, a front fixing block, a back fixing block, a first hydraulic telescopic rod, a first lug base, a material grabbing base block and four fixing lugs; each self-stabilizing branched chain comprises an installation block, an upper support rod, a lower support rod, a second lug base, a third lug base, a hydraulic cylinder, a self-stabilizing base block and a connecting spring, wherein the installation block is connected with the fixing lugs through bolts, the tail end of the upper support rod is provided with a first lifting lug, the lower side of the upper support rod is connected with an upper support block in a welded mode, and the upper support rod is welded to the installation block. The self-stabilizing type hydraulic supporting device solves the problem that the phenomenon that materials drop or a worker is hurt is caused by existing grab bucket equipment shakes in the material grabbing process, and has the advantages of being good in stabilizing performance, small in material grabbing shake, good in safety performance, high in working efficiency and the like.
