For different requirements of users, high-quality diesel engine of Cummins or Yuchai and at least 24 bar large F.A.D., top of the line dual-stage screw air compressor used.
Hole Diameter Range:Φ178-230 mm



Servicing the Surface Iron Mine Drill Rigs ZEGA D480A is easy with access to all key components such as the engine, fluid levels and compressor through large panel doors located at ground level for maintenance when needed.

The ZEGA D480A surface drill rigs’ cabs have been redesigned to provide operators maximum comfort with single-lever drilling controls, digital gauges, and superior views of drilling operation.

ZEGA D480A Heavy automatic integrated DTH surface Drill Rigs widely used in hole diameter range at φ178‒230 mm. And it optimum hole diameter is φ178mm.


ZEGA D480A widely used in iron mine, gold mine, other kinds of open pit mines, construction, surface mines and quarries, demolition, civil engineering construction, building construction and so on.

Drill Rigs FAQ

  1. Q: What is the fault of too slow drilling speed?

A: 1) The air volume is insufficient and the air pressure is too low. Increase the air supply volume and check the connector for air leakage.

2) If the air supply pipeline is small or too long, replace the air duct and shorten the air circuit.

3) The thrust is insufficient, and the thrust is increased.

4) The drill hole is displaced, and the resistance of the impactor and drill pipe is too large when they are running at the edge. Adjust the rack immediately, reduce the thrust, move up and down while rotating, and trim the hole wall.

5) The drill bit is blunt, and it should be repaired or replaced.

6) The internal parts of the impactor are worn. Check and replace them after cleaning.

7) If there is too much water in the air bag or the pipeline freezes in winter, the air bag shall be drained to remove the ice.

  1. Q: What is the fault of drill pipe run out?

A: It is possible to drop rocks or pass through the intersection of rock changes, or drop alloy sheets; If the alloy sheet falls into the fault, the alloy sheet can be squeezed into the fault. If it cannot be taken out, the above method shall be adopted
