Boom lifts are among the most versatile pieces of aerial equipment on the market. Their ability to provide both vertical and horizontal reach makes them essential for a wide range of jobsite tasks, from heavy construction and facility maintenance to tree care and sign installation. But with multiple types of boom lifts available—each designed for specific challenges—it’s important to understand which model best fits your needs.

In this guide, we break down the most common types of boom lifts, where they shine in real-world applications, and what makes each one different from the others.

‍

What Is a Boom Lift?

A boom lift is a type of aerial work platform (AWP) that uses an extendable arm to lift workers and tools into elevated positions. Boom lifts offer much more flexibility than scissor lifts or vertical mast lifts, particularly in situations where you need to reach up and over obstacles or cover long horizontal distances. They are commonly used in construction, utility work, building maintenance, and landscaping.

Types of Boom Lifts and Their Applications

‍

Articulating Boom Lifts (Knuckle Booms)

Articulating boom lifts have multiple pivot points in their arm, allowing them to bend like a finger and maneuver around obstacles. This makes them perfect for working in tight spaces or areas with overhead obstructions.

Common real-world uses:

• Commercial HVAC maintenance: Technicians use articulating booms to reach rooftop units around parapet walls or existing ductwork without disassembling components.
• Exterior building repairs: Painters, masons, or glaziers often need to access balconies, cornices, or awkward window placements that are unreachable by scissor lifts.
• Factory maintenance: Indoor electric articulating lifts allow maintenance crews to navigate around overhead cranes, ducting, or production equipment safely.
• Theme parks or sports arenas: Technicians use articulating booms to access lighting rigs or sound systems above stadium seating without damaging the infrastructure.

What sets them apart: Articulating boom lifts are best when you need to work around fixed obstacles or access hard-to-reach corners without repositioning the base of the machine.

‍

Telescopic Boom Lifts (Straight Booms)

Telescopic boom lifts feature a straight arm that extends outward, providing the greatest horizontal outreach of any aerial platform. These lifts are ideal for applications that require long-distance access or maximum elevation.

Common real-world uses:

• Bridge and overpass construction: Crews rely on telescopic booms to perform inspections, install beams, or weld sections from a distance, especially when working from ground level is not possible.
• Wind turbine servicing: Workers use high-reach telescopic lifts to inspect or repair turbine blades that can sit over 200 feet in the air.
• High-rise building work: These lifts are often used on urban jobsites where reaching up from the street to the top floors or roofs is critical.
• Airport maintenance: Telescopic boom lifts are used to inspect and maintain lighting systems, radar arrays, and air traffic infrastructure without disrupting operations on the ground.

What sets them apart: Telescopic boom lifts deliver unmatched height and outreach, making them the go-to option for wide-open sites or vertical projects with minimal obstructions.

‍

Towable Boom Lifts (Trailer-Mounted)

Towable boom lifts are compact, lightweight machines that can be hitched to a standard pickup truck. They are commonly chosen for quick jobs or locations where transporting heavier equipment is impractical.

Common real-world uses:

• Residential tree trimming: Landscapers and arborists use towable booms to access limbs in hard-to-reach backyards or driveways where larger lifts can’t maneuver.
• Sign and banner installation: Small marketing or sign crews often use towable lifts to install wall signs, holiday lights, or banners on buildings and lamp posts.
• Exterior home projects: Homeowners or contractors might rent a towable boom for projects like painting, gutter replacement, or light fixture installation.

What sets them apart: Towable boom lifts are easy to transport and don’t require a flatbed or forklift to move. They’re ideal for homeowners, DIYers, or contractors working short-term jobs on flat terrain.

‍

Spider Lifts

Spider lifts are compact aerial platforms with multi-jointed arms and track-style undercarriages. They’re lightweight enough to operate on delicate flooring or grass and narrow enough to pass through standard double doors.

Common real-world uses:

• Church steeple maintenance: Their lightweight design and vertical reach make spider lifts perfect for work inside sanctuaries where traditional lifts would damage flooring or can’t fit through doors.
• Atrium and mall lighting work: Facilities crews use spider lifts to replace bulbs or clean skylights in high-ceiling areas where scaffolding would be time-consuming or impractical.
• Historic property maintenance: For projects that require working on older buildings, spider lifts minimize damage to sensitive landscaping or surfaces.
• Tree trimming near landscaped gardens: Arborists use spider lifts to access tree canopies in tight or decorative spaces without tearing up turf or irrigation systems.

What sets them apart: Spider lifts combine compact design with excellent height and reach, making them the best choice for delicate indoor or landscaped environments.

‍

What Makes Boom Lifts Different from Other Aerial Equipment?

Compared to scissor lifts or vertical mast lifts, boom lifts provide more reach, flexibility, and maneuverability. Where a scissor lift can only move vertically and requires a level, open surface, a boom lift can extend outward, bend around obstacles, and operate on uneven terrain (especially rough-terrain or 4WD models).

Additionally, boom lifts typically offer:

• Higher working heights (often over 100 ft.)
• Better horizontal outreach (essential for utility work or façade access)
• Platform rotation and jib articulation for precise positioning
• Options for electric (indoor) or diesel (outdoor) power
