The invention relates to a lifting device for lifting a tubular pile which 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.
本发明涉及一种用于提升管桩的提升装置,包括:包括中心线的起吊构件、以围绕中心线相对于彼此的角距离可移动地安装到起吊构件的多个接合元件、及用于使各自的接合元件相对于起吊构件移动的致动器。接合元件可在中心线的纵向方向上沿起吊构件的各自导向装置移动。导向装置相对于中心线而倾斜,使得当使接合元件在中心线的纵向方向上移动时接合元件在中心线的径向方向上移动。各致动器功能性地互连,使得在操作状态下致动器使接合元件同时移动直到致动器中第一致动器达到比致动器中的第二致动器更高的反作用力,之后使致动器中第一致动器进一步移动。
