ABSTRACT:
A system for lifting and moving an object includes a vertical post (2), having a transversal lifting arm (38) rotatably connected thereto for rotation about a vertical axis thereof. The vertical post includes a weight (5) acting as a piston connected to a carriage (50) slidably mounted on the lifting arm, such that down and up displacements of the weight by gravity or pressurized fluid respectively lower and raise the object accordingly.
