Bucket Truck Buyer's Guide: How to Choose the Right Aerial Lift

A bucket truck is a 10-to-20-year capital investment. The wrong one — too short, wrong insulation class, wrong chassis size — is not a small inconvenience. It's a unit that can't do the job you bought it for, or worse, one that creates a safety hazard on energized work. This guide covers the four decisions that determine the right bucket truck for your operation, and maps those decisions to the units we carry.

Quick Reference: Which Bucket Truck for Your Application?

Decision 1: How High Do You Actually Need to Reach?

Working height is not the same as vertical reach. Working height adds approximately 6 feet to vertical reach to account for the height of a standing operator in the bucket above the bucket floor. A unit rated at 45-foot vertical reach provides a working height of approximately 51 feet. When you're comparing specs, use vertical reach to compare units against each other, and use working height to compare against the structure height you need to reach.

Match height class to your actual structures — not your most optimistic future use case. A bucket truck bought "just in case we need more height someday" that routinely operates at 60% of its rated height is heavier, more expensive, and harder to maneuver than a correctly-sized unit. Buy for your primary application.

Small Class: 35–45 ft Working Height

This is the most common height class for municipal fleets, landscaping companies, and general contractors. Most streetlights run at 28–35 ft pole height. Most residential trees top out under 45 ft. The Altec AT37G at 37 ft and the SkyCommand 45 at 45 ft cover this entire range. A Class 3 or 4 truck chassis works at these heights — keeping the overall rig weight in a range where a standard commercial driver's license is typically sufficient.

Medium Class: 50–65 ft Working Height

Distribution-class utility work lives in this range. The majority of overhead distribution lines in the US attach at pole heights of 35–55 ft. Add OSHA-required safe approach distances and you need a bucket that can reach 50–65 ft working height to service these structures safely. The Altec AA55-MH, TowerReach 55, Terex Hi-Ranger XT55, and Elliott L60 all operate in this class. For non-utility applications like tree service and sign work, the Elliott L60's 37-foot horizontal reach makes it the standout in the group.

Large Class: 70+ ft Working Height

This is transmission line territory. High-voltage transmission structures typically run 60–100 ft tall. The Altec AM900 at 75-foot working height covers the lower portion of the transmission height spectrum, plus rural distribution upgrades and any tall structure maintenance requiring a heavy-duty unit. These machines mount on Class 7 or 8 chassis — CDL and specific operator training are required.

Decision 2: Do You Need Electrical Insulation?

This is not a performance decision. It is a regulatory and safety requirement.

If your workers will be working within OSHA minimum approach distances of energized overhead lines — or making contact with energized conductors during live-line work — you need a Class E insulated bucket truck. Full stop. There is no other option that complies with OSHA 1910.269 or OSHA 1926.950 for energized line work.

Class E insulation means the upper boom and bucket assembly is rated to 40,000 volts (40 kV) per ANSI/SIA A92.2. The fiberglass upper boom and bucket physically isolate the worker from ground potential. The insulation must be tested annually via dielectric test — and units like the Terex Hi-Ranger XT55 have a built-in test port that enables in-field testing without disassembly.

For non-utility applications — tree service, construction, sign installation, municipal maintenance on non-energized structures — non-insulated units are the correct choice. They are lighter, less expensive, and perform the same mechanically. Do not buy a more expensive insulated unit for applications that do not require it.

Decision 3: One Person or Two?

Bucket capacity is listed in pounds, but the real decision is one-person versus two-person.

Most single-person buckets are rated at 300–400 lb. Two-person buckets typically run 500–750 lb. The weight rating matters — exceed it and you've voided the machine's certification. But the practical question is: does your work require two workers in the bucket at the same time?

For utility line work, the answer is almost always yes. OSHA 1910.269 requires a minimum of two workers for many energized line tasks. For telecom and CATV installation — splicing fiber, running drops, making connections — two-person crews are the operational standard. The Versalift VST-40 is built specifically for this application with a two-person bucket at the 40-foot height class.

For tree service, landscaping, and single-technician maintenance work, a single-person bucket keeps the unit lighter and simpler. The Altec AT37G is built for exactly this application — one operator, maximum maneuverability, compact footprint.

Decision 4: What Truck Chassis Can You Operate?

Bucket truck boom assemblies mount on a separate truck chassis — the chassis is not included. The boom manufacturer rates each unit for specific chassis classes, and your chassis choice has downstream effects on the vehicle weight, licensing requirements, and operational costs.

The chassis class determines the total rig weight with the boom assembly installed. A Class 3 chassis with a 3,100 lb boom assembly from the Altec AT37G stays within non-CDL GVWR range in most configurations. A Class 7 chassis with the 10,400 lb Altec AM900 boom assembly requires CDL for every operator. Account for chassis licensing requirements before you buy the boom — retrofitting a boom onto an underpowered chassis creates structural and safety problems.

New vs. Used: What Actually Matters

The used bucket truck market is large and active. A 10-to-15-year-old unit from a major manufacturer can be a legitimate value if you know what to inspect. Two things matter above everything else:

Dielectric testing history for insulated units. An insulated bucket truck that has not had annual dielectric testing per ANSI/SIA A92.2 is not certified for energized line work regardless of its physical condition. Request the complete test history. If it's missing, the insulation must be retested before the unit can be used on energized work — budget accordingly.

Structural inspection. Boom structures accumulate fatigue from years of use. A qualified third-party structural inspection is worth the cost on any used aerial unit. Hydraulic systems are repairable. Structural failures are not.

Boom Lifts vs. Bucket Trucks: What's the Difference?

Boom lifts (articulating and telescopic) and bucket trucks look similar from a distance but serve different operational roles. Bucket trucks are truck-mounted and self-propelled on the road — they drive to the job and operate from the truck. Boom lifts are freestanding machines transported to the job site on a trailer or flatbed.

For work that moves up and down a road (utility maintenance, streetlight work), a bucket truck is operationally correct — it drives down the street and stops at each pole. For construction sites and fixed locations, a boom lift is often more practical — it positions independently of a truck chassis and can be repositioned around the site without moving a full-size truck.
