FIELD: handling machines used for lifting works.

SUBSTANCE: self-propelled cart has height increasing device pivotally connected with support for rotating through an angle of about 180º between folded rear position and unfolded front position. Drive mechanisms for controlling rotation in pivotal joint of height increasing device are formed as jack and leverage mechanism. Support has supporting device for height increasing device folded to rear position. Telescopic boom base is pivotally connected with height increasing device for rotation through an angle 180° between folded position on height increasing device and position where it is aligned with height increasing position. Other drive mechanisms for controlling rotation of telescopic boom serve for rotating this boom through an angle of 180° relative to height increasing device and also comprise jack and leverage mechanism. Front end of telescopic boom is equipped with transition device for replaceable receiving of various working tools.

EFFECT: increased zone for servicing of self-propelled cart.
