The present invention concerns a counterbalancing structure (1) for counterbalancing a load, where the counterbalancing structure (1) has support means (3) for the support of the load, said support means (3) being able to rotate along a plane or vertical plane () with respect to a first axis or vertical axis (y) laying on said plane (), a first movable pulley group (2) having at least a first upper pulley (4, 5), precompressed elastic means (10), and at least a rope or line (11, 12) fixed at a first end to said elastic means (10) and at the second end to the support means (3), the at least a rope (11, 12) passing at least on at least a first upper pulley (4, 5) such to act in compression on the elastic means (10) when the load is coupled to the support means (3).

The present disclosure relates to a system for transmitting power. The system comprises a first component which includes a first cable winch configured to rotate to at least partially wind and unwind a first cable on the first cable winch. The system comprises a second component which includes a second cable winch configured to rotate to at least partially wind and unwind a second cable on the second cable winch. The first component comprises a first engagement device and the second component comprises a second engagement device configured to selectively engage with the first engagement device to couple and decouple the first cable winch and the second cable winch to and from each other, respectively. The present disclosure further relates to an assisting device and a method of operating a system.
