Excavators are essential machines in construction, mining, and demolition projects. Over time, components wear out, making it crucial to replace them with quality parts.
In this guide, we’ll explore the core systems and parts excavator owners need to know, highlight popular brands like Hitachi, Takeuchi, Volvo, and Caterpillar (Cat), and explain how to find the best excavator for parts.
Key Excavator Components Explained
Excavators have multiple systems that work together for performance and efficiency. Here are the main parts of an excavator:
Boom: It’s the part that gives the excavator its extended reach.
Stick (or Dipper Arm): Attached to the boom, it allows for digging and extending deeper into the ground.
Bucket: Used for digging, trenching, and lifting materials.
Cab: Modern cabs offer comfort and protection.
Undercarriage: Tracks are often replaced due to wear.
Engine: Usually a diesel-powered unit that supports hydraulic and mechanical systems.
Hydraulic System: Requires regular maintenance to prevent leaks and breakdowns.
Swing Drive: Allows the excavator to rotate 360 degrees.
Counterweight: Balances the machine during operation.
Each of these components can wear out or become damaged with time, requiring replacement. That’s when contractors look for excavator for parts options to keep their machines running.
Why Buy an Excavator for Parts?
When a machine is beyond repair or retired from active use, it can still be valuable as a source of parts.
Benefits of using excavators for parts:
Save money by using salvaged components.
Promotes sustainability in the construction industry.
Ideal for discontinued or rare models.
Useful when operating multiple machines of the same brand.
This method is especially popular in regions where new parts are expensive or unavailable.
