Provided is a lifting device with a force-absorbing base to which a boom with hoisting cable for lifting a load in substantially vertical direction is tiltably connected. The lifting device is provided with an auxiliary device for counteracting tipover of the boom in the case of sudden loss of load. The auxiliary device is connected to the base of the lifting device, provides a contact surface which is in permanent contact with a contact surface of the boom or comes into contact therewith in the case of tipover, and further comprises a drive and control system which is configured to stop the boom movement when a predetermined force between the contact surfaces is exceeded as a result of the boom tipping over. The described auxiliary device can take an autonomous form and can be arranged on a lifting device.
