FIELD: construction.
SUBSTANCE: group of inventions pertain to construction, namely, to hydraulic hammers hung on to construction excavators. Method of protection of the excavator from the influence of hydraulic hammer blowing mass of the hammer pin over the wedge of the hydraulic hammer according to which oscillation damping of the working equipment from the mass action of the hammer pin during its idle run is performed through main hydraulic cylinders of lead control. Oscillation damping of the working equipment is performed both through the main hydraulic cylinder and through a balancing pneumatic - hydraulic cylinder. Whereat balancing pneumatic - hydraulic cylinder is made with constant gas pressure characteristic, and head ends of main hydraulic cylinders of lead control are connected with hydropneumatic accumulator with variable characteristic of gas pressure in its air bladder.
EFFECT: facilitation of hydraulic hammer operation.
