The invention relates to a self-stabilizing type hydraulic grab bucket device which comprises a moving rack, four self-stabilizing branched chains and a material grabbing branched chain. The self-stabilizing branched chains are symmetrically installed on the two sides of the moving rack through bolts, and the material grabbing branched chain is welded to the lower end of the moving rack; 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; the material grabbing branched chain comprises a second hydraulic telescopic rod, an upper fixing sleeve, a lower fixing sleeve, a limit spring and two material grabbing mechanisms. The self-stabilizing type hydraulic grab bucket device can achieve the stable and shakeless material grabbing function, 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.
