Used Cat 320 Excavator For Sale In UK
The Caterpillar 320 excavator remains a benchmark machine for contractors seeking versatile power in the 21-tonne class. When you are hunting for a used Cat 320 for sale in the UK, focus on provenance, maintenance history, and suitability for the job rather than simply price. This machine has global acclaim for its hydraulics, fuel efficiency, and operator comfort—not to mention parts availability within the UK supply chain—making it an astute purchase for groundworks, infrastructure, and demolition projects.
Why the Cat 320?
Operators praise the Cat 320 for its outstanding balance between lift capacity and mobility. On used units you’ll still find:
- Proven hydraulics: Cat’s hydraulic system gives smooth, predictable response for precise grading and loading.
- Fuel efficiency: Modern Cat 320s (especially the later E-models) carry Tier 4 Final engines calibrated to cut consumption without sacrificing power.
- Operator comfort: Remote diagnostics, superior cab visibility, heated seating, and climate control keep crews productive through UK weather extremes.
A used Cat 320 that’s been serviced at authorised Cat dealers will typically have well-documented filter and oil changes, which is crucial when you’re still investing capital.
What to Check Before Buying
Buying used requires scrutiny. Key inspection points include:
- Track and undercarriage condition – Track links, rollers, and idlers can be pricey if worn. Measure wear and plan for replacement costs if the machine has upwards of 6,000 hours.
- Hydraulic leaks – Inspect boom, stick, and bucket circuits. Leaks hint at cylinder seal failure or hose fatigue, both costly.
- Engine hours and service history – Confirm consistent maintenance, ideally via Cat’s service records. Machines maintained by Cat dealers often have built-in Cat Connect data.
- Structural integrity – Look for welds or repairs on the boom, dipper, and frame. Avoid machines with evidence of misuse or signs of overloading.
A reputable UK seller will allow you to conduct a walkaround and, if needed, arrange a pre-purchase inspection with a qualified mechanic.
Sourcing Options Across the UK
Used Cat 320 excavators can be sourced through:
- Cat dealers: Multiple Cat dealerships across the UK (e.g., Rix, Finning, Finning UK) sell inspected, warranted used units.
- General plant dealers: Companies like Plantworx, Marshall, and HHD also offer quality used machines with service histories.
- Online marketplaces: Platforms such as Mascus, Machinery Trader, and Ritchie Bros. offer listings. Filter by UK location, year, and hours to compare.
Look for listings that mention:
- Machine serial number
- Attachments included (thumbs, tiltrotators, GP buckets)
- Certifications (MOT-style LOLER for lifting attachments if relevant)
- Transport logistics (UK delivery or ports serviced)
Financing, Warranty, and Support
Used Cat equipment can still qualify for financing through Cat Financial or independent brokers, aiding cash flow for contractors. Dealers often provide limited warranties or refurbished units with Cat Certification, which can reduce risk.
Don’t overlook post-sale support. Many dealers offer:
- Cat Extended Service Plans (ESP) for continued coverage on major components.
- Training on the Cat Grade Assist or Cat Command control systems that newer 320s include.
- Parts and availability through Cat parts centres, ensuring uptime.
Getting the Most Value
To maximise your investment:
- Compare machines from multiple sellers and have a mechanic verify any claims.
- Factor in UK transport costs (road haulage or ferry) and VAT implications if buying from Europe.
- Confirm attachments match the intended work; excavators with general purpose and ditching buckets add flexibility.
A well-maintained used Cat 320 in the UK can perform reliably for another 8,000+ hours with proper upkeep. Prioritise machines with full histories, recent undercarriage replacements, and clean hydraulic systems to keep your fleet running efficiently.
