LIFTING BOOM FOR LIFTING OF CONCRETE PRODUCTS AND METHOD OF LIFTING OF CONCRETE PRODUCTS WITH LIFTING BOOM

摘要

FIELD: ground construction.;SUBSTANCE: invention relates to devices for lifting concrete products. To lift concrete products with a lifting boom, the lifting boom is moved above the concrete product to be lifted with a crane, lifting hooks (8, 8') of the lifting boom are set in lifting loops located in the concrete product to be lifted, and the lifting is carried out by lifting the lifting boom together with the concrete product with a crane. Location of at least one lifting loop in the concrete product to be lifted is detected by control system (15) of lifting boom (1), which moves at least one lifting hook (8, 8') along the lifting boom to the location of the lifting loop.;EFFECT: improved safety and reduction in labour intensity.;11 cl, 4 dwg
