description Earth-moving equipment enabling earth beneath a linear obstacle, such as a rail, to be quickly removed and employing only one person for its operation, comprising a supporting body, intended to be suspended from a crane, and a two-winged grab, in which the wings are specular in relation to a longitudinal plane and can be moved at an angle on opening and closing around their hinges by the action of control devices, the said hinges being supported by the supporting body in a moveable manner reciprocally to move apart and together by the action of movement devices.
