A gripper device () which is designed so as to be movable along a movement path, and which serves for grasping and holding a workpiece () and for moving the workpiece along the movement path, with at least one first contact section () which, to produce an operative pairing with the workpiece that effects the gripping or holding action, can be driven relative to a second contact section (), which first contact section is assigned actuator means (), which are designed to exert a drive force in reaction to the application of a magnetic field, and which are composed of a magnetic shape-memory alloy material, wherein the actuator means for magnetic interaction are formed, for the application of a magnetic field, with magnetic field generating means that are static at one position of the movement path (), and/or with magnetic field generating means that are provided so as to be movable independently of the gripper device.
