A pincer grab is provided having a frame, two jaws pivotally mounted to the frame which can come together and form a grab, a hydraulic drive cylinder, and transmission between the drive unit and the jaws. The hydraulic cylinder is coupled at both ends using U-shaped coupling members, via pivot joints, to two respective pairs of transmitting arms, each connected to a jaw. The transmission is substantially free of residual stresses.
