FIELD: vertically sliding mechanisms.

SUBSTANCE: invention relates to vertically sliding (straightening) mechanisms, namely to portable or stationary folding masts for various types of light sources. Folding mast system for lifting the light source, comprising a stationary base having a first end and a second end, a lower lifting lever having a first end and a second end, with the first end of the lower lifting lever connected to the base, a drive attached to the base and the lower lifting lever, an upper lifting lever having a first end and a second end, with the first end being designed to mount the light source on it, and a 4-rod connecting mechanism, connecting the second end of the lower lifting lever to the second end of the upper lifting lever in a rotational position with each other.

EFFECT: creation of a folding lighting mast, which is characterized by less complexity, ease of manufacture, while at the same time providing possibility of complete vertical straightening of the lighting mast using a single drive (actuator).
