FIELD: construction engineering. SUBSTANCE: rod-like tapered members to be extracted from ground are of cross-section which is uniformly reduced from bottom to top. These tapered members are preferably used as reinforced concrete contact-line supports of electric railway. Device has gripping attachment made according to configuration of side surface of rod-like tapered member, and supporting plate with hydraulic cylinders which are powered by hydraulic pump unit. Application of aforesaid embodiment of device allows for retaining rod-like tapered member fully intact with reliable extracting it from ground. EFFECT: higher efficiency. 4 cl, 4 dwg
