The invention relates to a rotatable hydraulic grab bucket. The rotatable hydraulic grab bucket comprises a first mounting box, a second mounting box, a first oil pipe, a clamping assembly and a shielding assembly, wherein the top of the second mounting box extends into the first mounting box, a hydraulic oil tank and a hydraulic oil pump are arranged in the second mounting box, an oil cylinder isarranged at the bottom of the second mounting box, the first oil pipe enables the hydraulic oil tank to communicate with the oil cylinder, a connecting column is arranged at the bottom of the oil cylinder, jaw plates are connected with third mounting lugs, two ends of first hydraulic rods are correspondingly connected with first mounting lugs and second mounting lugs, second oil pipes enable theoil cylinder to communicate with the first hydraulic rods, third oil pipes enable the oil cylinder to communicate with oil grooves, fourth oil pipes enable the oil grooves to communicate with second hydraulic rods, the tops of arc-shaped baffles are rotationally connected with the bottoms of the second hydraulic rods, third sliding blocks are arranged on the arc-shaped baffles, and two ends of ropes are connected with fixed blocks and third sliding blocks respectively. According to the rotatable hydraulic grab bucket, the material grabbing angle can be rotationally adjusted; and by arranging the shielding assembly, the material clamping area is increased, the material clamping efficiency is improved, and meanwhile the risk of high-altitude object falling is reduced.
