Link-Belt excavators are well-regarded in the construction and heavy machinery industry for their durability, precision, and innovative engineering. Link-Belt Construction Equipment Company, established in the early 20th century, initially produced cranes and later expanded into hydraulic excavators. The brand has a long-standing reputation for robust undercarriage systems, advanced hydraulic controls, and versatile attachments. Used Link-Belt excavators remain popular due to their longevity and adaptability in both construction and mining operations.
Terminology Explained
Used Link-Belt excavators cover a wide range of sizes and configurations, from compact models to large mining machines. Key specifications include:
Operational Insights
Operators value used Link-Belt excavators for their responsive hydraulics and stable performance on uneven terrain. The swing mechanism allows for continuous operation without repositioning the undercarriage, which enhances efficiency on large worksites. Many models include auxiliary hydraulic circuits for attachments such as breakers, grapples, and augers.
Maintenance Considerations
Buying a used Link-Belt excavator requires careful evaluation of critical components:
Construction companies using used Link-Belt excavators report that these machines often outperform other brands in longevity and reliability. One anecdote involved a model operating on a quarry site for over 12 years with minimal major repairs, emphasizing the brand’s durable hydraulic components and solid undercarriage design.
Operators also highlight the ease of retrofitting attachments and performing preventive maintenance, which contributes to lower overall operating costs.
Recommendations for Buyers
Used Link-Belt excavators offer a combination of durability, precise hydraulics, and flexible functionality. Their long service life and adaptability to diverse environments make them a valuable choice for contractors, mining operations, and heavy construction projects. Proper inspection, preventive maintenance, and operator training ensure continued performance and cost efficiency in the long term.
Terminology Explained
- Hydraulic Excavator – A machine that uses pressurized hydraulic fluid to power its arm, boom, and bucket.
- Undercarriage – The system of tracks, rollers, idlers, and sprockets supporting the excavator’s weight and movement.
- Bucket Capacity – Volume of material a bucket can hold, usually measured in cubic meters or cubic yards.
- Swing Mechanism – Hydraulic system allowing the upper structure to rotate independently of the undercarriage.
- Cycle Time – Time required for one full operation of digging, lifting, and dumping material.
Used Link-Belt excavators cover a wide range of sizes and configurations, from compact models to large mining machines. Key specifications include:
- Operating weight: 10,000–50,000 kg depending on the model
- Engine output: 90–350 horsepower
- Bucket capacity: 0.5–2.5 m³ for general-purpose models
- Hydraulic flow: 120–350 L/min
- Track type: Standard steel tracks with optional rubber for sensitive surfaces

Maintenance Considerations
Buying a used Link-Belt excavator requires careful evaluation of critical components:
- Undercarriage Wear – Inspect rollers, sprockets, and tracks for wear or damage, especially in high-hour units.
- Hydraulic System – Check for leaks, pressure drops, and fluid contamination. Replace filters regularly.
- Engine Health – Examine turbochargers, injectors, and cooling systems to prevent overheating or power loss.
- Swing and Boom Bearings – Look for excessive play or unusual noises, which may indicate wear.
- Sluggish arm movement may indicate low hydraulic pressure or worn pump components.
- Uneven track wear can result from misalignment, poor tension, or damaged rollers.
- Engine performance issues may be traced to fuel quality, clogged filters, or injector problems.

Recommendations for Buyers
- Conduct a thorough inspection of the undercarriage and hydraulic systems.
- Verify service history, including oil changes, track replacements, and filter maintenance.
- Test swing and boom responsiveness before purchase.
- Evaluate attachment compatibility and hydraulic auxiliary circuits for current or future needs.
- Consider total hours of operation in relation to resale value and remaining service life.
