FIELD: driving of reinforced concrete piles in industrial and construction engineering. SUBSTANCE: hydraulic pile-driving hammer has guides on upper and lower supports for carrying moving hammer connected by flexible connection with hinge of hydraulic cylinder rod whose body is connected with upper support by additional hinge. Flexible connection is formed by cross-piece carrying said rod hinge and connected with hammer by means of upper and lower shock absorbers. Said additional hinge is of cardan type. Hammer is removable for its replacement with hammers of different weights. Hydraulic cylinder has upper rod whose diameter is smaller than that of rod with hinge. Hammer has a system of control of piston motion of hydraulic cylinder and includes electrical and hydraulic parts. Hydraulic part includes hydraulic control valve, pneumohydroaccumulator and hydraulic apparatuses, supplying and discharging hoses connected with respective ends of hydraulic cylinder. EFFECT: higher reliability and efficiency of pile-driving work. 5 cl, 6 dwg ЕЕРЗУЗГЕС ПЧ ГЭ РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ ЗВО”” 2184 811 ' (51) МПК? 13) Сл Е 02 0 7/10 12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 2001106217/03, 12.03.2001 (24) Дата начала действия патента: 12.03.2001 (46) Дата публикации: 10.07.2002 (56) Ссылки: 4$ 3669198 А, 13.06.1972.
