Zusammenfassung:	FIELD: construction engineering. SUBSTANCE: hydraulic hammer can be used for compaction of ground, destruction of concrete structures, pile driving and for other similar operations. Hydraulic hammer has body which houses centrifugal vibrator. Centrifugal vibrator accommodates hydraulic motors which bring in rotation two flywheels rotating opposite to each other. Each of them has its own hydraulic control system, hydraulic accumulator, and working cylinder with piston or equalizing member. During rotation of flywheels, pistons or equalizing members are shifted synchronously in diametrically positioned cylinders, thus varying value of unbalanced weight in each of flywheels. Application of aforesaid embodiment of device allows for increasing efficiency and performance characteristics of hydraulic hammer due to higher power of single-side action of working tool. EFFECT: higher efficiency. 3 cl, 6 dwg
