Tunnel breaker
 
The following functions are added to enable the breaker to be more durable even under the harsher operating conditios peculiar to tunneling:

• The T-BOX type frame has been designed to especially realize sound suppression and vibration isolation, as well as extended durability.

• Air compressor piping design prevents water/dust/earth/sand from entering the breaker main unit.

• A water sprinking nozzle is provided at the end of the frame, which helps prevent fine rock particles from scattering within the mining pit.

• Auto grease piping automatically delivers lubrication to the front section, thus helping to further improve durability of the front section.
  * Prepare an air compressor.

 
Underwater breaker
 
A simplified, easily maintained (as compared with conventional models) air compressor piping connection port that attaches to the back head. Also, a check valve (inside the breaker main unit) acts to effectively externally discharge air, thus preventing entrance of water, dust, earth and sand.
