When you invest in a used digger derrick truck, you’re buying more than a piece of machinery — you’re investing in productivity, uptime, and safety. Heavy equipment breakdowns are linked to poor maintenance habits that lead to up to 40% construction project costs. Regular upkeep isn’t just about keeping things running — it’s the key to maximizing the lifespan of your equipment and protecting your investment.

For businesses that rely on the best digger derrick trucks for lifting, drilling, and setting poles, maintenance isn’t optional — it’s essential. Here’s how maintaining used digger derrick trucks can keep your fleet performing like new for years to come.

1. Keep Your Hydraulic System in Top Condition

The hydraulic system is the heart of every digger derrick truck. It powers the boom, auger, and lifting functions. Contamination or fluid breakdown can quickly lead to sluggish performance or costly damage.

Maintenance tips:

• Check hydraulic fluid levels daily and top off with the manufacturer-recommended oil.
• Replace filters on schedule to prevent particle contamination.
• Inspect hoses and fittings for leaks, cracks, or signs of abrasion.
• Flush the system at regular intervals to remove debris and moisture.

A clean and properly maintained hydraulic system ensures smoother movement, faster response, and fewer repair bills over time.

2. Inspect the Boom Regularly

Booms endure tremendous stress during operation. Regular inspections help prevent small cracks or misalignments from turning into safety hazards.

Here’s what to check:

• Look for corrosion, dents, or weld fatigue on the boom sections.
• Test rotation and extension for smooth, unrestricted motion.
• Verify that boom pins and bushings are properly greased.
• Inspect safety locks and load limiters for correct operation.

Performing a visual check before each job takes only minutes but can save thousands in potential repairs — or worse, job-site accidents.

3. Maintain the Auger and Drill Components

The auger faces some of the toughest working conditions, especially in rocky or clay-heavy soil. Regular upkeep ensures efficient drilling and consistent torque delivery.

Best practices include:

• Sharpen or replace worn teeth and cutting edges.
• Keep auger flights clean and free from caked dirt or debris.
• Inspect drive shafts and gearboxes for play or unusual noise.
• Lubricate moving parts according to the service manual.

A well-maintained auger cuts faster, wears evenly, and keeps your entire system running smoothly.
