A lifting device for lifting a tubular pile comprises a hoisting member including a centreline, a plurality of engagement elements which are moveably mounted to the hoisting member at angular distance with respect to each other about the centreline and actuators for moving the respective engagement elements with respect to the hoisting member. The engagement elements are moveable in longitudinal direction of the centreline along respective guides of the hoisting member. The guides are inclined with respect to the centreline such that the engagement elements move in radial direction of the centreline when being moved in longitudinal direction of the centreline. The actuators are functionally interconnected such that under operating conditions the actuators move the engagements elements simultaneously until a first one of the actuators reaches a counterforce which is higher than a counterforce of a second one of the actuators, after which the second one of the actuators is moved further.
