The last two drill heads are capable of drilling NMLC holes to 20 & 30 Metres.This rig gives a helping hand with hydraulic feed for those light duty and highly inaccessible sites. It is the lightest and smallest of our power feed drilling rigs. Our power packs and hand held drill can be removed and used independently. The mast will also lay down to the horizontal position.Drill head travel is around 2 metres with an over all height around 2.25 metres. An independent power feed is used to give the rig a push/pull capacity of 200 kg and fully variable speed of travel. (Operator pressure control on feed optional).

The power pack available 11 hp to 20 hp – 18HP Honda Twin outlet shown), not only drives the drilling rig head but also powers a 55 l/min triplex water pump (to 400 psi) and is mounted on two stainless steel water recycling tanks. The water recovery is made by feeding the water from the drill hole into a stand pipe and discharged into the under/over baffled tanks. The stand pipe is drilled a short way into the ground to provide a joint to re-cycle the water. The water pump is capable of pumping non lumpy Gypsllm/Bentontemit (“Earthron”) into the hole for final bonding.In sandy conditions the water pump can be used with jetting clamps which can be clamped onto 9/16″ or 5/8″ copper pipe and with an “Earthron” slurry, the copper pipe can be pushed straight into the sand, while ever the returning slurry along side the pipe keeps a fluid boundary between the pipe and the sand.
