Pressure relief drilling machines
|
These drills are suited to producing release holes with its gear that is equipped with a picking motion (impact drilling shaft). The firm rods are loosened by one-off (or repeated) reversing of the compressed air motor to
right/left running using the impact movement (of approximately 75). These machines were engineered for use under difficult conditions and are especially suited to large-diameter drilling with short lengths. Depending upon your specifications, these drills can be equipped with external mufflers that guarantee low-noise equipment running. |

Pressure relief drilling machine, type P 100-ES
|
 |
|
These drilling machines are designed modularly which means that they can be re-equipped underground without a great deal of effort by mounting the right
components. That means that they can carry out all drilling work that these machines can perform. |
