Inspecting your prospective used drilling rigs is crucial to make an informed new drill rig purchase and minimizing the risk of ugly surprises.

Here are our top 5 tips for inspecting a used drilling rig.

TOP 5 TIPS FOR INSPECTING A USED DRILLING RIG

1. CHECK THE LIFT CHAINS
   Inspect the lift chains attached to the mast for any cracks or missing parts that could cause them to break. Start at the bottom and work your way up, checking all attachment points for signs of impairment. Since these chains play a crucial role in lifting and lowering the rotation unit and drill string, it’s essential to take care of them.
   
2. INSPECT THE ENGINE
   Start the rig and let it run for a few minutes, then switch it off and open the engine compartment. Check the hoses for cracks or leaks, and inspect the belts for proper lubrication, tightness, and signs of wear. Verify that the engine has clean air filters and check the oil level using the dipstick. Low oil levels could indicate an engine leak.
   
3. SEARCH FOR LEAKS
   Check the rig for leaks around the hydraulic system, rotation unit, and engine compartment. Leaks could be a sign of damage and may result in additional repairs if you purchase the rig.
   
4. CONFIRM THE ODOMETER READING
   Check the odometer reading to get an estimate of the rig’s usage and expected lifespan. Verify that the odometer hasn’t been reset and compare the hours used to information about how long rigs typically last. If the main components show wear but the odometer shows a low reading, it could be a sign of odometer tampering.
   
5. VERIFY SAFETY FEATURES
   Before purchasing a used rig, ensure that all emergency stops and safety guards are in good working order. Check the hose whips and other safety features that keep your operators safe. Always prioritize operator safety when considering a purchase.
