Power extractor for Boom surface drills

Power Extractor is very efficient when the drill string are jammed so tight that it can not be removed by only using feed, rotation and percussion.

Description

Fractured and heterogeneous ground, poor flushing quality, cross drilling, or worn out rock tools can lead to drilling rod jamming, And It is quite hard work to recover from the jamming and it robs your job and production of expensive and valuable time.

In production drilling, one of the major loss of production cause could be the difficulty to uncouple efficiently the rods.

In order to solve these issues and preserve the productivity, Sandvik has developed the Power Extractor system.
Power Extractor is a module for a hydraulic rock drill, operated by a switch on the operator’s control panel.
An hydraulic actuator mounted on the front end of the rock drill gear housing, by multiple (small) pistons, is able to pull the shank adapter towards the striking point, so that the piston can hit the shank during pull-back.
Percussive stress waves can therefore be transmitted to the drill rods.

Power Extractor is very efficient when the drill string are jammed so tight that it can not be removed by only using feed, rotation and percussion.

Use of Power Extractor for uncoupling rods makes easier and faster the opening of joints. It reduces the non-drilling time, increases drilling capacity and rock tool service life and reduces rock drill maintenance cost.
