How to Buy a Used Rotary Drilling Rig: 7-Step Guide

When buying a used rotary drilling rig, first confirm project requirements: pile diameter, depth and soil conditions. Step 2: Verify actual working hours and manufacturing year with maintenance records. Step 3: Request real jobsite photos and test-run videos — not stock images. Step 4: Arrange third-party inspection (SGS/TUV) focusing on engine, hydraulics, rotary drive and kelly bar. Step 5: Confirm refurbishment and pre-shipment preparation scope. Step 6: Clarify Incoterms (FOB/CIF) and destination port logistics. Step 7: Include inspection standards, payment milestones and after-sales SLA in the contract.
