FIELD: construction engineering. SUBSTANCE: this is for erection of fodder storages of various diameter and with height of up to 16-18 m. Mounted on T-shaped frame is central column of scaffolding and installed on this column are indicators with rollers on their rods. During rotation of scaffolding around hollow column, rollers are running on internal surface of storage wall and displace rods. These displacements of rods are indicated on scale with accuracy to one millimeter, and vertical walls are checked by installing indicators at two levels. EFFECT: high efficiency. 2 cl, 6 dwg
