Tunnel breaker The following functions are added to enable the breaker to be more durable even under the harsher operating conditions peculiar to tunneling: 1. The T-BOX type frame has been designed to especially realize sound suppression and vibration isolation, as well as extended durability. 2. Air compressor piping design prevents water/dust/earth/sand from entering the breaker main unit. 3. A water sprinkling nozzle is provided at the end of the frame, which helps prevent fine rock particles from scattering within the mining pit. 4. 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 breaker main unit is provided at the upper section of 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. *Prepare an air compressor.

Types of rods Selecting an appropriate rod is required according to the nature of work and the characteristics of the object to break. Use: FURUKAWA Genuine ROD

Moil point

Flat rod

Multipurpose applications, including breaking of extra hard rock, hard rock, hard stone, and reinforced concrete, as well as excavation of bedrock.

Secondary breaking in quarries, boulder breaking, concrete breaking, and slab breaking.

Wedge point

Concrete breaking, excavation of bedrock, operations on the face of slope, excavation of ditches, etc.

Ball point rod

Breaking metal ores, as well as quartzite and other highly abrasive objects.

Control Valve

During a long stroke, at the instant that the object to be crushed has been broken, idle blow of the piston normally occurs, but with the F-series, it is automatically eliminated.

Number-of-blows manual adjustment function Standard Stepless adjustment is possible via the adjuster. Further, spool replacement allow selection of “idle blow” and “idle blow prevention” during a long stroke. ( “idle blow prevention” type fitted as standard )
