Buying a pre owned aerial unit can save serious budget, but only if the truck passes a proper safety review. A lot of incidents are connected to improper lift operation, many of which stem from worn components, hydraulic issues, or skipped inspections. This is why a full bucket truck safety inspection is the first step before selecting any unit. With the right checks, buyers can avoid unexpected downtime and protect operators from preventable hazards.

Boom Structure and Fiberglass Condition

The boom is the heart of any aerial unit. Before considering a used bucket truck, inspect the entire boom for cracks, stress lines, soft spots, and previous repair marks. Fiberglass booms should be tested for dielectric performance to confirm they meet OSHA and ANSI A92.2 requirements for insulated operation. Any sign of UV damage, swelling, or delamination calls for further evaluation. Boom rotation and extension should be smooth, with no sticking, grinding, or unexpected drift.

Hydraulic System Performance

Hydraulics power every movement in used bucket trucks. A full check of cylinders, hoses, valves, and seals is essential. Look for leaks around fittings and joints. Test lift, lower, rotate, and extend functions to confirm consistent pressure. Listen for irregular pump noise, slow response, or sudden jerks. Poor hydraulic performance is one of the most common reasons aerial units fail on job sites. Inspect the reservoir for contamination and confirm that filters have been changed at proper intervals.

Chassis Stability and Mounting Points

Even the best boom becomes unsafe if the chassis is compromised. Review the frame for corrosion, cracks, and previous weld repairs. Verify that the boom pedestal is firmly mounted with no movement at attachment points. Test stabilizers or outriggers to ensure they extend and retract without hesitation. On Altec bucket trucks and similar models, stabilizers play a major role in lift safety, so any wobble or sag during operation must be addressed immediately.

Electrical and Control Function Checks

Aerial lifts depend on responsive controls. Review lower and upper controls for worn switches, loose wiring, or delayed response. Emergency stop switches must activate instantly. For insulated units, confirm that electrical components meet the required safety rating. Inspect bucket controls for stickiness or inconsistent feedback. Faulty electronics can cause sudden boom behavior, which raises risk for the operator and people on the ground.

OSHA and ANSI Compliance Review

Buyers should request documentation for annual OSHA and ANSI inspections. A properly maintained unit will have clear service logs, dielectric test records, hydraulic service notes, and repair documentation. Missing records or gaps in testing history indicate that more evaluation is needed before buying.

Visual Bucket and Safety Gear Inspection

Check the bucket for cracks, mounting wear, and damage from previous impacts. Inspect safety lanyard attachment points and confirm they meet load requirements. Review harness systems and anchor hooks if included.
