Drilling rig with 300 plus feet of drill pipe in 10 foot sections ,several tricone bits,1 carbide bit. clamps and other small items.Runs off 240 volts A/C. My brother and his friend used this around 18 years ago. If used in the field a 240 volt a/c generator or power supply would be needed. Would be best to renew wiring in control cabinet and new motor contactors and maybe a control cabinet made of metal not wood. I have NOT drilled any holes with this but had the electric motors running many years ago. Needs new wiring and mud dauber wasps in the motors cleaned out at least. The tires do not hold air and they are mobile home style rims and tires so hauling on a separate trailer would be best. I am not very knowledgeable on this unit other then how the electrics and cables work. A fair amount of work went into constructing this. $4500 or offer.
