A method for filling a gripper for bulk material, with the gripper being suspended on holding cables, raised and lowered by a crane via a controller, and acting on the bulk material with the gripper weight during the closing and filling process. By reducing the effect of the weight of the gripper on the bulk material, a fill degree of the gripper is influenced via the controller in that a tensile force acting on the holding cables is influenced in order to optimally fill the gripper. A tensile force TARGET value is determined for the holding cables via the controller and is output to a tensile force controller as an input variable. An electric motor for lifting and lowering the gripper is controlled by the tensile force controller, and an ascertained tensile force ACTUAL value of the holding cables is supplied to the tensile force controller as an input variable.
