A HYDRAULICALLY CONTROLLED FLAT GRAB BUCKET Abstract The present invention relates to a hydraulically controlled flat grab bucket including an upper bearing beam, lower bearing beam and a bucket body. The upper and lower bearing beams are connected through a bucket opening hydraulic cylinder. The bucket body is hingedly connected with the lower bearing beam. The upper bearing beam includes at least one strut guide unit, which includes a strut control hydraulic cylinder and a strut. One end of the strut is hingedly connected with the bucket body. The other end of the strut is connected with the strut control hydraulic cylinder. The hydraulically controlled flat grab bucket further includes a hydraulic control device which controls the function of a bucket opening hydraulic cylinder and the strut control hydraulic cylinder. The advantages of the present invention include: 1) Simple construction and easy operability; 2) Smoother, more level dredging of riverbeds or seabeds to meet more stringent development requirements; and 3) Increased maximum bucket grab width and digging depth and easy variation to meet the needs of different jobs and applications. ----- k--- - Fig r 1~~~. -- ----t -------- ...~ ......
