Mini Rig MR131- Winch Feed
|A Light very portable diamond drilling Rig for installing electrical earthing stakes & other light diamond drilling investigations requiring low cost & 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.The mast, hand feed aids in lifting the drill rods and provides a controlled feed with a double acting pawl to hold a load or thrust up to 300 kg (limited by machine weight) on the diamond drill bit.The mast is easily broken down to a base, mast, hand held capable drill head 13 hp Honda power pack (power packs available 11 to 20 hp), 2 adjustable stays ,and 55 l/min triplex water pump (to 400 psi) optionally mounted on 2 or 3 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 Gypsum/Bentonite/Calcium mix 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. A length of copper pipe can be jetted in down in about 5 minutes if all goes well.
