Over 70% of utility companies rely on used bucket trucks to handle high-reach jobs. But here’s the problem: a surprising number of these trucks hit the resale market with hidden mechanical issues, unsafe lifts, or outdated hydraulics. One missed detail can cost thousands—or worse, cause an accident.

If you’re eyeing a bucket truck for sale, don’t just kick the tires. A thorough used bucket truck inspection is the smartest move you’ll make before signing a check.

1. Start with the Boom and Bucket

This is where safety matters most.

Check the fiberglass for cracks, chips, or wear—even minor ones compromise electrical insulation. Test the boom’s articulation through the full range of motion. Listen for hissing, grinding, or lagging movement.

Next, examine the bucket’s weight capacity label. If it’s worn off or unreadable, that’s a red flag. Look at the liner condition, safety harness anchor points, and inspect for non-functioning bucket controls.

Pro tip: Ask for the last dielectric test record. This should be done every 12 months.

2. Inspect the Hydraulic System

Leaking seals or slow response times are often the death of a good deal.

Check:

• Hydraulic fluid color and level
• Cylinders for pitting or scoring
• Hoses for wear or cracking
• Pump operation during cold starts

A sluggish hydraulic system on a used bucket truck signals bigger issues down the road.

3. Chassis and Frame: Not Just the Foundation

The truck itself needs to carry more than weight—it needs to hold up over time.

Inspect:

• Frame rails for signs of stress or prior weld repairs
• Suspension components, especially leaf springs and bushings
• Axles and U-bolts for rust or structural damage
• Tire tread and sidewalls

Don’t forget to check for uneven wear—this could signal alignment or suspension problems.

4. Engine and Transmission Health

Pop the hood. Run a cold start. Let it idle, then drive it.

Look for:

• Smoke color (black = fuel, blue = oil, white = coolant)
• Smooth gear shifts without jerks or delays
• Fluid leaks under the engine or transmission
• Warning lights that flicker or stay on

A used bucket truck inspection should also include a compression test for older trucks.

5. Electrical Systems and Lighting

Bucket trucks often work after sunset.

Ensure:

• All markers and work lights function
• Outrigger control panel lights work correctly
• Interior gauges and displays are accurate
• Battery voltage and alternator output are within spec

Inspect for exposed wiring and corroded connectors.

6. Outriggers: Stability First

Outriggers keep your crew and truck grounded during operation.

Test for:

• Smooth, even extension and retraction
• Leaks in hydraulic rams
• Cracked or bent pads
• Malfunctioning safety interlocks

Any stiffness, uneven lift, or instability means the truck isn’t ready for work.

7. Cab Comfort and Control Panel Function

The inside of the cab should feel maintained—not neglected.

• Check seat condition, air conditioning, heater, and control knobs
• Inspect the dashboard warning lights for function during ignition
• Verify that safety and override systems can be accessed from the driver’s seat

These things might feel minor—until they aren’t.
