Buying used heavy equipment is one of the smartest ways to control capital costs, a well-maintained used machine can deliver 80–90% of the productivity of a new one at a fraction of the price. But a bad purchase can cost far more than it saves in downtime and repairs. This guide walks you through exactly what to check, how to judge condition, and how to avoid the most common (and expensive) mistakes.
1. Before you look at a single machine
Get clear on three things first:
- The job. Match the machine to the actual work — dig depth, lift height and capacity, reach, terrain, and duty cycle.
- Total cost of ownership. Purchase price is only part of it. Factor in transport, import duties, spare-parts availability, fuel, and expected repairs.
- Your walk-away number. Decide the maximum you’ll pay before you fall in love with a machine.
2. The universal inspection checklist
Whatever the category, always check these:
- Hours and age. Compare hours against age and ask for the service history. Very low hours on an old machine can mean it sat idle just as easily as light use.
- Fluids and leaks. Look for fresh oil, coolant, or hydraulic fluid on the ground; milky or burnt oil signals trouble.
- Undercarriage and structure. On tracked machines the undercarriage can be 20% of the value. Look for cracks and poor re-welds everywhere.
- Cold start. Insist on a cold start — excessive white/blue smoke or knocking points to engine issues.
- Operate under load. Run every function and watch for drift, slow cycles, jerky hydraulics, or overheating.
- Fault codes. Ask to see the diagnostic screen and any stored codes.
3. What to check by category
Excavators: undercarriage wear, boom/arm cracks, swing bearing play, bucket and pin condition. Wheel loaders & dozers: transmission shifting under load, articulation joint play, edge wear. Telehandlers & forklifts: boom wear pads and chains, fork condition, mast smoothness, capacity plate. Cranes: wire rope, hook and block, boom sections, and valid inspection/load-test certificates. Trucks & trailers: engine and transmission health, brakes, chassis cracks, suspension.
4. Paperwork you must verify
- Ownership/title free of liens or finance
- Service and maintenance records
- Inspection & certification (mandatory for cranes/lifting)
- Matching serial/PIN plates
- Import/export documents for cross-border purchases
5. How used equipment is priced
Value is driven by hours and condition, brand and model reputation, year and emissions tier, attachments included, location and transport, and market demand. Always benchmark an asking price against comparable listings before you negotiate.
6. Red flags — walk away or dig deeper
- Seller won’t allow a cold start or load test
- No service history and vague answers about hours
- Fresh paint hiding welds, or mismatched panels
- Milky engine oil or metallic hydraulic fluid
- A price far below market with pressure to pay fast
- Missing or altered serial/PIN plates
