Buying a Truck Mounted Water Well Drilling Rig
If you're shopping for a truck mounted drilling rig for water well work, you're probably comparing prices and trying to figure out what's a good deal. Whether you're buying new or used, there are a few key things you need to know to get the best value for your money. Here's a buyer's guide to help you make the right choice.
New vs. Used: The Big Decision
New Rigs. Pros: warranty, latest technology, no surprises, you know exactly what you're getting. Cons: expensive, and you lose 20-30% the second you drive it off the lot. If you're just starting out and don't have a mechanic on staff, buying new is safer.
Used Rigs. Pros: much cheaper, you can get a bigger rig for the same money. Cons: hidden problems, no warranty, you have to know what you're looking at. If you have a good mechanic who knows drilling rigs, used can be a great deal. If not, stay away.
What to Check When Buying Used
If you're looking at a used rig, bring a mechanic with you. Check these things:
The Chassis. How many miles? Is it rusty? Does it start easily? The chassis is the foundation — if it's bad, everything else is wasted.
The Rotary Head. Check for leaks, unusual noises, and play in the bearings. Run it at full speed for a few minutes and feel the temperature. If it gets too hot to touch, something's wrong.
The Mud Pump. Test the mud pump under pressure. Check the seals for leaks. A worn-out mud pump is expensive to replace.
The Mast. Inspect the mast for cracks, especially at the welds. Look at the telescoping sections — do they move smoothly? Is there any excessive play?
