A lifting device for handling and/or moving loads, including two vertical booms which via one of their ends are pivotally connected to a base and via their opposite ends are pivotally connected to a horizontal beam, forming a frame for the lifting device wherein at least one cylinder is connected to at least one of the vertical booms so as to be able to turn the lifting device around the pivot point. The horizontal beam is further pivotally connected to at least one tension rod. The vertical booms, the tension rods and the horizontal beam will then be pivotal in relation to each other. By means of the present invention, a less torque-critical lifting device is provided, as the vertical booms, when handling and/or moving a load, will take up compressive forces, while the tension rods will take up tensile forces. |
