20 Ton Used Excavator Caterpillar Brand Cat 320GX Precise Operation Secondhand Digger

While many focus on new heavy equipment, this case study demonstrates how 20 refurbished Cat 320GX excavators (21-ton class) became the workhorses of a large-scale rural development project in Indonesia, delivering fuel efficiency, durability, and versatility at a fraction of the cost of new machines.

Key Applications & Advantages
1. Road & Bridge Construction
12 excavators were deployed to build 45km of reinforced roads in mountainous terrain.

Their 187 HP Cat C7.1 engines provided optimal power while consuming 15% less fuel than older models.

Advanced hydraulics allowed smooth grading and precise digging, even on steep slopes.

2. Riverbank Stabilization
6 units equipped with long-reach arms (up to 12.5m) placed 3,500 tons of rock boulders to prevent erosion.

Sealed undercarriages minimized wear in muddy conditions, extending service life.

3. Agricultural Land Development
2 excavators fitted with ripper attachments cleared tree roots and prepared 200+ hectares for farming.

Eco-mode operation reduced fuel consumption by 20% during light-duty tasks.

Why Choose Used Cat 320GX?
✔ Proven Reliability – Simple mechanical design ensures easy maintenance in remote areas.
✔ Fuel & Cost Savings – GX series optimizes efficiency, lowering operating costs.
✔ Attachment Flexibility – Quick couplers allow rapid switching between buckets, breakers, and grapples.

Post-Project Results
After 8 months of intensive use, all 20 machines remained operational with 92% availability, proving that well-maintained used Cat 320GX excavators offer exceptional value for large-scale infrastructure projects.

This deployment highlights how strategic fleet utilization of used heavy equipment can achieve high productivity at lower costs, making it an ideal choice for budget-conscious contractor
