Zusammenfassung:FIELD: mechanical engineering; load lifting facilities. ^ SUBSTANCE: proposed load-lifting boom has lifting section with drive hydraulic cylinder hinge-connected with multisection telescopic boom with its drive hydraulic cylinders of its extension and telescopic sections and mechanical extensions, and end connectors for connecting hydraulic cylinders and butt-joining of working members with hydraulic main lines delivering working liquid. In said load-lifting boom design of its components is optimized, including places of hinge-coupling of lifting section with upper end of slewing gear post and extension section of telescopic boom, end connectors, hydraulic cylinders and other units. Boom is provided with drum-type devices to deliver working liquid and transmit electric signals to hydraulic and electrified working members and headlights-searchlights for illumination of site. ^ EFFECT: facilitated manufacturing, improved performance characteristics. ^ 7 cl, 87 dwg
