摘要： A gripper arrangement for a lifting or hoisting apparatus serves to transport workpieces having a journal or plug-like end. This gripper arrangement or gripper contains a housing in which two slides are essentially symmetrically arranged and radially displaceably guided with respect to a primary or main axis. At each of the slides there is supported a respective clamping or chucking jaw by means of a related guide device which is connected with the related clamping jaw by means of a radial inner hinge joint and with the related slide by means of a radial outer hinge joint which is arranged further towards the outside in axial direction than the radial inner hinge joint. Within the housing there is rotatably mounted a control body member which is operatively coupled with a drive motor. At the control body member there are formed control cams which, during rotation of the control body member, displace the slides. The axial symmetrically displaceable slides render possible, on the one hand, an accommodation of the gripper to workpieces having different journal or plug diameters and, on the other hand, a rapid, rigid or firm and exactly central clamping or chucking of the journal or plug-like end of each individual workpiece which is handled.
