Mini Rig Portable Diamond Drill
Mini Rig MR153-2
|Model 153-2A Light very portable diamond drilling rig for light diamond drilling investigations and installing electrical earthing stakes which require low cost and high portability. Drill heads used are the RD121E (1500rpm), RD193E (900rpm) & RD244E (600rpm). 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). A range of drill heads give a top speed of 1500 rpm (E rod), 900 rpm (E Rod), down to 350 rpm (A Rod), and torques between 30 Nm to 200 Nm.|
The choice of power packs vary from 6.5 hp to 18 hp petrol or diesel engines. Although not shown installed with the mast, they actually fit into the mast base to add weight the rig. Mast length overall 2600 mm with stay,length of base 1220 mm, Width of base 665 mm weight 20Kg. Drill carriage mast excluding drill head motor & water swivel, 38 Kg, hand held drill head weight 10 Kg, Console, valves & hoses about 18 Kg (depends or what is required and varies from rig to rig.
|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.|
