Whether you're building roads, digging foundations, or handling heavy materials, excavators play a critical role. 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.
Understanding the Main Parts of an Excavator
Excavators have multiple systems that work together for performance and efficiency. Here are the primary parts of an excavator:
Boom: Responsible for reaching and lifting, the boom is a vital hydraulic arm.
Stick (or Dipper Arm): Controls the distance between the machine and the bucket.
Bucket: One of the most replaced parts excavator owners need.
Cab: Equipped with joysticks, screens, and safety features.
Undercarriage: Provides mobility on rugged terrain.
Engine: Powers the entire machine.
Hydraulic System: Drives the boom, stick, bucket, and other attachments.
Swing Drive: Important for maneuvering on tight sites.
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.
Environmentally friendly by recycling old machinery.
Older excavators may not have parts in production.
Useful when operating multiple machines of the same brand.
Rather than buying new, sourcing used parts from similar machines can extend equipment life.
