FIELD: mining and construction machinery, particularly for construction member driving in ground in inclined and in horizontal directions, as well as for trenchless underground pipeline laying by perforation method. ^ SUBSTANCE: hammer comprises body 1 with striker 2 slidably installed in the body, anvil block 4 and drive 3 connected with striker through flexible member 5. Guiding means 6, 7 are created in side surfaces of body 1. The guiding means have inclined 6 and horizontal 7 sections adapted to support striker 2 provided with legs 8. Flexible member 5 in upper extreme position of striker 2 is parallel to inclined section 6 of guiding means. Longitudinal axis of flexible member 5 passes through center of striker 2 gravity. ^ EFFECT: increased efficiency of construction member driving in ground in inclined and horizontal positions. ^ 1 dwg |
