Discussion on Excavator Vertical Digging Depth

[MikePhua]

This discussion focuses on the maximum vertical digging depth of various small to medium-sized excavators, especially those ranging from 1 ton to 8 tons. Users shared their real-world experiences and advice on the topic.
Key Points:
Definition of Digging Depth
Vertical digging depth refers to the vertical distance from the ground level down to the maximum depth that the excavator bucket can reach.
Variations by Model

• Different excavator models vary greatly in vertical digging depth due to their design and structural differences.
  
• Examples:
  • Smaller machines like Komatsu PC26 and Hitachi ZX26 have digging depths around 3 meters.
    
  • Larger models such as Komatsu PC78 can reach about 4 meters or more.
    
  • Compact models like Kubota U27 or Bobcat E35 also achieve nearly 3 meters.
    

Factors Affecting Digging Depth

• Length and design of the boom and arm.
  
• Bucket size and configuration.
  
• Machine stability and working radius.
  
• Ground conditions and operator skill.
  

Practical Suggestions

• Select an excavator model based on your required digging depth.
  
• Note that stated digging depths are reference values; in actual work, boom reach and width constraints must be considered.
  
• For deeper digging needs, some machines offer optional extended booms or longer dipper arms.
  

Other User Discussions

• Official manufacturer digging depth specs may vary considerably; practical, real-world measurements are often more reliable.
  
• It’s recommended to prioritize machines that perform well in your typical working environment.
  

Summary
Vertical digging depth is an important specification when choosing an excavator. Generally, small excavators from 1 to 3 tons have digging depths between 2.5 to 3 meters, while medium excavators from 5 to 8 tons can reach 3.5 meters or more. Besides the machine’s parameters, terrain, working method, and attachments also influence effective digging depth. Buyers should carefully evaluate their actual needs and working conditions before selecting a machine.
