The utility model relates to a remote control hydraulic grab bucket. Control boxes are arranged below a lower balance beam and above a bucket body; oil boxes are arranged above the bucket body and under the control boxes; two hydraulic oil cylinders are arranged between an upper bearing beam and a lower bearing beam; the hydraulic oil cylinders are connected to the lower bearing beam; piston rods of the hydraulic oil cylinders are connected to the upper bearing beam; an oil inlet of a cylinder body of each hydraulic oil cylinder is connected with an electromagnetic control valve; the electromagnetic control valve is connected with each oil boxes; an oil outlet of the cylinder body of each hydraulic oil cylinder is connected with a one-way valve; and the one-way valve is connected with each oil box. The open grab bucket is controlled by a wireless remote control emitter. Ascending and descending as well as closing of the grab bucket are controlled by a lifting mechanism. A remote control system operates a hydraulic system to realize opening of the grab bucket. The remote control hydraulic grab bucket has the characteristics, such as simple structure and using reliability, of a rope type grab bucket, and also has the characteristics, such as high loading and unloading efficiency, of a power type grab bucket. The remote control hydraulic grab bucket can meet the requirement of a quay crane on safe and high-efficient loading and unloading of bulk goods.
