A lifting device includes a framework () and a manipulator arm () pivotally connected to the framework. The manipulator arm includes a first end portion () and a second end portion () adapted to carry a tool (). A balancing arrangement () includes a first part () connected to the framework and a second part () adapted to interact with the first end portion. At least one of the manipulator arm and the balancing arrangement includes a first balancing device (), which is extendable to ensure that interaction between the second part and the first end portion is maintained. The first balancing device is adapted to generate a first balancing force which maintains a moment balance about the first joint. The manipulator arm has at least two rotational degrees of freedom in a first spherical coordinate system (). 113-. (canceled)1411.
