Abstract (en)
[origin: CN111827385A] The invention relates to a slotted wall gripper and method for creating a slot in the ground; the slotted wall gripper is used, wherein the slotted wall gripper has a grab frame at the lower end of which two grab blades are arranged and can be adjusted between an open position and a closed position by means of an actuating device. Gripper shovels grab soil material and pick the same up in the closed position. According to the gripper disclosed in the invention, a distance and/or a pressure is determined by means of a measuring device when the gripper shovels are closed, and the measuring device forwards measured values determined to a control unit, which is designed to provide information on the basis of the measured values determined by the measuring device to hit the soil material.
