FIELD: transport.
SUBSTANCE: invention relates to self-propelled hoisting cranes. This crane (1) has telescopic boom (9) with at least four barrels (16, 17, 18, 19). Every said barrel has at least two sections (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31), that compose the telescopic structure in lengthwise direction (L). In cross-section relative said lengthwise direction (L) said barrel sections are spaced apart to make barrel sections (11, 12, 13) with at least one bending-stiff connector (32, 33, 34, 35).
EFFECT: higher working load owing to increased moment of inertia for boom area.
