A bucket truck inspection is the operator's daily check of an aerial device before anyone goes up: the truck itself, the set-up on firm ground with chocks and outriggers down, the boom, turntable and hydraulics, both sets of controls and the emergency lowering, the bucket, its liner and the anchorage the operator clips to. For tree crews it adds the parts that matter near trees and wires: the hydraulic tool circuit, the insulated boom and its last dielectric test, and power-line awareness. This checklist scores each item and ends with a clear decision on whether the truck goes up today.

Set-up decides most of the risk
Most aerial lift incidents in tree work start on the ground: a truck on soft soil or too steep a grade, outriggers not fully down or without pads, wheels not chocked, a drop zone that overlaps the truck, or a boom swung into a line nobody looked up at. This form checks the set-up before the boom moves, including wind and weather against the maker's limits.
Controls and getting down
The lower controls must work every function and be able to take over from the bucket. The upper controls must be clearly marked and return to neutral when released. The emergency stop must stop the boom, and the emergency or auxiliary lowering system must bring the bucket down if the main power fails. Each of these is a safety check, and the crew on the ground should know how to use the lower controls and the emergency lowering without looking it up.
Insulated booms and the dielectric test
If the truck has an insulated aerial device, a gated section asks for the date of its last dielectric test, typed from the test sticker or certificate, and whether that test is current as your program requires. ANSI A92.2 is the standard most US insulated aerial devices are tested to. The insulated section of the boom and the bucket liner must be clean, dry and undamaged, and nothing conductive should bridge the insulation.
Near power lines
Where any part of the work is within reach of overhead conductors, the form records the minimum approach distance the crew used, as their qualification, state and the utility's rules require, and checks that the operator is qualified for that work, that the utility was contacted where needed, and that someone on the ground is watching the boom. It does not state a distance as law; ANSI Z133 and your utility set those for your work.
Common questions
How often should a bucket truck be inspected?
The operator checks it before each day's use, and a fuller frequent and periodic inspection follows the maker's manual and the standard your company works to. This form is the daily, pre-use check.
How often is a dielectric test required on a bucket truck?
It depends on the standard your company follows, the device's category and how it is used. This form does not set an interval; it records the date of the last test and whether it is current as your program requires.
What is the minimum approach distance for tree work near power lines?
It depends on the voltage, on whether the worker is a qualified line-clearance arborist, and on your state and the utility. ANSI Z133 sets out the distances most tree crews work to. This form records the distance your crew used rather than stating one.
Does the operator need to wear a harness in the bucket?
Most makers and safety standards expect a body harness with a short lanyard clipped to the anchorage the maker provides on the boom or bucket. The form checks that it is worn and attached to that point.
Does completing this checklist mean the truck is compliant?
It records what was checked, what was found, the dielectric test date and who decided whether the truck could be used. Whether a truck or a crew meets ANSI A92.2, ANSI Z133 or any other rule is judged against that document.
