• Shipping Length: About 32 feet 3 inches
  
• Transport Width: Ranges from 10 feet 6 inches to 11 feet 3 inches depending on track shoe size (600mm to 850mm)
  
• Tail Swing Radius: Approximately 6 feet 3 inches, notably smaller than many standard excavators, facilitating tight space operation
  
• Ground Clearance: About 1 foot 8 inches
  
• Track Gauge: Around 8 feet 6 inches
  

Boom and Reach Options

• Boom reach stands at 20 feet 2 inches with over 34 feet maximum reach at ground level, allowing for substantial coverage on worksites.
  
• Stick options vary between 8 feet 8 inches and 10 feet 6 inches, offering versatility for different excavation depths and applications.
  
• Maximum digging depth ranges from around 20 feet 11 inches to 22 feet 8 inches depending on boom and stick configuration.
  

Performance and Power

• Outlet driven by a Cat C7 ACERT engine producing roughly 204 horsepower, ensuring robust yet efficient power delivery.
  
• Operating weight is approximately 87,850 pounds (around 39,830 kilograms), providing stability with the reduced tail swing design.
  
• Hydraulic flow rate sits near 62 gallons per minute, supporting smooth operation of attachments.
  

Bucket and Digging Forces

• The machine carries buckets around 1.2 cubic meters (1.57 cubic yards) in capacity.
  
• Maximum bucket digging force reaches approximately 45,000 pounds force (200 kN), suitable for tough digging jobs.
  
• Stick digging forces are around 29,000 to 34,000 pounds force, accommodating various soil conditions.
  

Operator Comfort and Features

• Cabin height approximately 10 feet with ergonomic design, increasing operator comfort and visibility.
  
• Intuitive controls and optional technologies support operator efficiency and safety during precise excavation tasks.
  

Applications and Advantages

• The reduced tail swing radius enables work near walls, urban sites, and densely packed environments, where standard excavators may struggle.
  
• Excellent for utility installation, landscaping, and site development with limited workspace.
  
• Reliable powertrain and hydraulic system deliver consistent performance across diverse conditions.
  

Glossary

• LCR (Long Carriage Radius): Design format balancing compact rear swing with longer undercarriage base for stability.
  
• Boom: Main arm component used for reach and excavation.
  
• Stick: Secondary arm section adjusting reach and digging depth.
  
• Tail Swing Radius: The minimum clearance required at rear when excavator rotates.
  
• Digging Force: Measured power of bucket and stick to penetrate soil.
  

Summary
The Caterpillar 328D LCR stands out as a powerful, maneuverable hydraulic excavator designed for work in tight or restricted areas. Its compact size combined with strong digging capabilities and enhanced operator comfort make it a strong choice for urban construction, utility maintenance, and general excavation needs. Its dimensions, strength, and durability reflect Caterpillar’s legacy of building reliable, high-performance machinery for demanding job sites.
