A gripping device is adapted for handling equipment with a drill string, wherein an annular actuator housing includes a hydraulically activated, rotatable cam disc which is arranged to displace a number of locking slides from a first position, in which the locking slides are retracted into the actuator housing, and a second position, in which the locking slides are in engagement with the drill string extending through a center opening in the gripping device, by abutting against a shoulder of a tool joint in the drill string. The gripping device is connected to a hydraulic supply and return for the actuation of the cam disc via a hydraulic coupler in a connection port on the actuator housing. Alternatively pressurizing and ventilating two adjacent actuation volumes in the cam disc brings about rotation of the cam disc within a sector of the cam disc.
