Beschreibung
Zusammenfassung:	FIELD: construction machinery, particularly pile driving means. ^ SUBSTANCE: pile driver comprises movable platform, mast installed on the platform and provided with guiding means and pile driving means, drilling equipment, drive and two additional masts. All three masts are installed on the platform and restricted from rotation about their axes. Drilling equipment is installed on two additional masts. Length of drilling tool installed on one mast is at least 2 times smaller than that of drilling tool mounted on another mast. The larger drilling tool and pile driving means are mutually located so that vertical axes projections onto vertical plane parallel to longitudinal pile driver axis are spaced apart a distance equal to movable plant travel. ^ EFFECT: simplified mast structure and reduced hole drilling time. ^ 3 dwg
