The shell of the excavator crushing hammer completely covers the hammer body, and the shell is equipped with vibration damping material, which can reduce the vibration of the carrier while creating a buffer between the hammer body and the shell.

The box type hydraulic crushing hammer can provide better protection for the hammer body, 

low noise, reduce the vibration of the carrier, and also solve the problem of loosening the shell. 

As a general user, it is necessary to choose the most suitable hydraulic crushing hammer according to various comprehensive considerations.

The power source of the hydraulic crushing hammer is the pressure oil provided by the pump station of the excavator or loader. 

It can be used to dig the foundation of the building more effectively to clean floating stones and rock crevices in the dirt. 

The principle of choosing a hydraulic crushing hammer is to choose the most suitable hydraulic crushing hammer according to the type of excavator and the operating environment.

The working principle of excavator hydraulic crushing hammer:

The kinetic energy of the accumulator drives the cylinder rod upward to compress the nitrogen chamber, and after pushing to the high point, the reversing valve switches

 the direction. The kinetic energy of the hydraulic oil inlet and nitrogen compression drives the cylinder rod rapidly downward to knock the drill rod to complete the 

crushing work.

The correct use of excavator hydraulic crushing hammer:

1, the drill rod is perpendicular to the hitting surface, compacting the drill rod (inclined to break the drill rod and damage the cylinder,

 not compacting the drill rod empty will cause damage to the cylinder).

2. The engine should be warmed for ten minutes before crushing operation, especially in winter, which will help smooth operation; 

Before crushing, visually check whether each oil pipe leaks oil, oil leakage should be handled in time, check whether the oil seal of

 the crushing hammer leaks oil, and replace the oil seal in time, otherwise the dust will enter the piston and wear the piston.
