PNEUMATIC (ANCHOR DRILL) PKU-1

The pneumatic anchor drilling machine PKU-1 is designed for drilling blast and anchor holes in the roof of tunnels in medium-hard and hard rocks with a tunnel height of 2600 mm and a pneumatic stroke of 1300 mm. It is also used for anchoring.

APPLICATION

The pneumatic anchor drilling machine PKU-1 is designed for drilling blasting and anchor holes into the ridges of medium-hard and hard rocks in structures with a height of 2600 mm, using a pneumatic support of 1300 mm, and for anchor installation.

Upon customer request, it is possible to manufacture an anchor machine with a different cylinder stroke. The PKU-1 anchor machine has the capability to adjust the position of the control valve based on the excavation height. This adjustment is made by the operator of the anchor machine at the operating station. This solution significantly reduces discomfort when working with the anchor machine. Maximum drilling diameter Ø45 mm.
