Everything you need to make your decision
The Altec AA55E is a 55-foot articulating aerial bucket truck featuring Altec's PowerLine electric auxiliary power system — a fully integrated electric drive that powers the boom independently of the truck's PTO when the engine is off. This electric auxiliary capability is the defining operational feature: linemen working on distribution circuits often need to operate the boom silently, at night, or in tight ROW where truck noise creates a hazard. The AA55E's electric mode runs on a vehicle-mounted battery bank charged by the truck's alternator while driving. Platform height reaches 55 feet (61 feet of working height) with 25 feet of horizontal outreach. The 500 lb single-person bucket is ANSI A92.2 rated. Four-point extendable outriggers with mudpads handle roadside and off-road shoulder positions. The AA55E mounts on a Class 5 or 6 truck chassis. Altec's 1,500+ location service network provides the most comprehensive aerial device field support in North America.

Watch the Altec AA55E Articulating Aerial Bucket Truck in action — full installation and operation demo.

Aerial bucket trucks use a truck-mounted hydraulic boom and articulating system to position a work bucket at height. The PTO-driven system draws power from the truck engine — boom operation requires the truck engine to be running.

PTO Engagement

Before operating the boom, engage the Power Take-Off (PTO) via the in-cab switch or lever. The PTO connects the truck's transmission output to the hydraulic pump. The truck must be in neutral (auto) or PTO gear (manual) before PTO engagement.

Outrigger Setup

Deploy all four outriggers before raising the boom. Place outrigger pads under each foot on soft or uneven ground. Confirm all four indicator lights show "set" (or physically verify leveling) before raising the boom above horizontal.

Boom Controls

Both platform (bucket) controls and base controls operate the boom. Platform controls replicate all boom functions with the addition of a platform rotation control. The base controls include an emergency override for all boom functions in the event of power loss in the bucket.

Emergency Lowering

A manual hydraulic override at the base of the boom lowers the platform in the event of engine failure or hydraulic system failure. The operator in the bucket should wear a full-body harness with a lanyard connected to the bucket's D-ring anchor at all times.

Note: Set up on level, firm ground whenever possible. If working on a slope or soft ground, use outrigger pads and check the manufacturer's rated operating slope. Exceeding the rated slope with the boom raised is the leading cause of bucket truck tip-overs.

⚙️ Outrigger Interlock

The boom cannot be raised above horizontal unless all four outriggers show confirmed ground contact. An electronic sensor in each outrigger pad signals the control system. A boom raised without full outrigger deployment is the primary cause of tip-overs in aerial truck incidents.

🛡️ Insulation Testing (Class E)

Insulated bucket trucks require annual dielectric testing per ANSI/SIA A92.2. The fiberglass upper boom and bucket are tested to their full rated voltage (40 kV for Class E). A test port on the unit allows in-field testing without removing components.

🔒 Platform Fall Arrest Anchor

A certified D-ring fall arrest anchor is welded into the bucket structure. All operators in the bucket must wear a full-body harness with the lanyard connected to this anchor at all times — OSHA 1910.67 requirement for aerial devices.

🚨 Emergency Lower / Override

A manual hydraulic override at the base of the boom lowers the platform to ground level independently of all electronic controls and truck power. Location and operation are marked clearly on the unit. Test this system at every pre-shift inspection.

How does this compare?

AA55E vs. XT55 at 55 feet: the AA55E offers Altec's electric auxiliary (engine-off boom operation) as its premium feature. The Terex XT55 offers overcenter boom reach as its premium feature. Choose the AA55E if silent operation or engine-off work is important to your application. Choose the XT55 if both-sides-of-the-truck reach from a single position is more valuable. Both are 55-foot ANSI-rated aerial devices; the choice comes down to operational requirement, not quality.
