FIELD: construction; laying of pipelines. SUBSTANCE: sheet is provided with several circular band slings positioned at angle and interconnected at places of their intersection. Slings are made of polyester or polyamide threads. They are impregnated and coated with polymeric compound. At places of resting on hook of load-lifting facility or supporting the pipeline, slings have antifriction wear-resistant coating. Places of pipeline supporting bands are secured to one another, thus forming an arc in unloaded state to facilitate movement of slings along pipeline. EFFECT: higher reliability of laying the large-diameter pipelines. 4 cl, 5 dwg
