The Top 5 Things to Check When Buying a Used Crane

Purchasing a used crane can be a smart move for companies looking to expand their capabilities without the cost of brand-new equipment. However, cranes are high

value assets with complex mechanical, hydraulic, and structural systems and overlooking the wrong detail could turn a bargain into a liability. Whether you’re buying for your own fleet

or brokering equipment, here are the top five things you should always check before purchasing a used crane.

1. Service and Maintenance Records

A crane’s history is one of the strongest indicators of its reliability. Always request complete maintenance logs, inspection reports, and repair documentation. Consistent servicing shows the machine was properly cared for, while gaps in the record may suggest hidden problems. Pay special attention to:

• Annual and periodic inspections

• Hydraulic system repairs or replacements

• Accident or damage reports

• OEM part replacements

Red flag: Missing or incomplete records. This could mean skipped maintenance, unreported accidents, or chronic issues.

2. Structural Integrity and Wear

A crane’s structural components take immense stress throughout its service life. Inspect the boom, jib, turntable, and outriggers for:

• Cracks, bends, or weld repairs

• Excessive corrosion, especially in harsh environments (coastal or industrial sites)

• Misalignments or unusual wear patterns

Even minor structural defects can compromise safety. In many cases, an experienced inspector should be brought in to conduct a detailed assessment.

3. Hydraulic and Mechanical Systems

Hydraulics are the lifeblood of most cranes, and failures here can be costly. Test and inspect:

• Hydraulic cylinders for leaks or scoring

• Hoses, seals, and fittings for wear

• Pump performance under load

• Winch, hoist, and slewing mechanisms

Tip: Operate the crane through a full cycle. Listen for unusual noises, observe response times, and check for smooth operation.

4. Electrical and Safety Systems

Modern cranes rely heavily on electronic systems for both operation and safety. Always confirm that:

• Limit switches, load moment indicators (LMI), and safety alarms function properly

• Wiring harnesses are intact, without splices or exposed wires

• Control panels and operator displays are clear and accurate

Faulty electronics not only create downtime but can lead to safety violations and accidents.

5. Certification and Compliance

A crane may look strong and operate smoothly, but if it doesn’t meet current regulations, it’s a risky investment. Before purchase, verify:

• Current inspection certifications (per OSHA, ANSI, or relevant regional standards)

• Compliance with emissions standards (especially for export)

• Whether it meets the buyer’s jobsite requirements and insurance coverage criteria

Buying a crane without proper certification can result in delays, costly upgrades, or outright rejection from worksites.

Final Thoughts

Buying a used crane can deliver huge savings, but only if you approach the deal with the right level of diligence. Always take the time to inspect service history, structural condition, hydraulic/mechanical systems, electrical and safety components, and certifications. When in doubt, partner with an independent crane consultant or inspection service to ensure you’re making a safe, compliant, and profitable investment.
