Ray Hydraulic hammer -Inward Valve type

Changzhou Raymond International Trading Co.,Ltd should be there. We specialized in earth auger ,digger attachments. As the demand and development of the market, hydraulic auger driller , quick coupler ,hydraulic shear and hydraulic  crusher that has become our main product for the domestic and foreign market.

Precision seamless steel pipe be used in gas spring, shock absorber ,hydraulic machinery and refrigeration industries

Hydraulic auger is the attachments of digger, loader, skid steer loaders. The function of digging hole such as tree planting , telecom vertical poles, landscape construction, power systems, wind energy, thermal energy system construction, etc.

For Hydraulic breaker, we have two kinds: Inward valve type & Outward valve type

Now, Ray attachments company introduce hydraulic breaker (Inward valve type) to you

1) Cylinder assembly

This contains the moving piston which strikes the tool. The seals for both ends of the piston are also located in the cylinder. The seals for the upper end of the piston are located in a removable seal retainer while the seals for the lower end of the piston are located in proves machined directly into the cylinder.

2) Piston

The piston transfers impact power to the tool, generated by hydraulic power.

3) Seal retainer

The seal retainer has oil seals to seal N2 gas in back head, and to prevent hydraulic oil leakage.

4) Valve

The valve controls reciprocates piston action with hydraulic fluid distribution.

5) Front head assembly

This retains the tool, using the tool pins.

By removing these pins, the tool can be changed.

6) Ring Bush

This guides the tool. Ring Bush limits the uppermost position of the tool.

It is consumable parts which should be checked for wear limits. If need it they should be replaced. 

7) Tool

This transfers piston impact power to the objects.

We recommend that various tool shapes according to working circumstance. 

8) Rod Pin

This is installed on the front head and prevents the tool from coming off.

9) Back head assembly

This contains the cushion chamber charged with N2 gas that is compressed during upward stokes of the piston and serves to provide maximum absorption of piston recoil, efficiency storing this energy for the next blow.

10) Through bolts

These are used to assemble the front head, the cylinder and the back head. They have to be constantly tightened to specified torque. Inspect the bolts for loosening and re-tighten them weekly.
