System and device for controlling a load lifting device

(57) Summary book invention relates to the system which controls load lift equipment (1) equipped with the lift component (2) which is connected with a controllable drive (2) and the above-mentioned drive (2), and is therefore aligned at least by gravity perpendicularly (Z*Z) in a non-actuated position. The above-mentioned system is further equipped with the regulation circuit for making load balance. The above-mentioned regulation circuit contains the equipment which generates the course dependence signal which shows the input signal for control of the above-mentioned drive (2) while corresponding to perpendicular (Z*Z) movement substantially the above-mentioned lift component (5).
