If you’ve ever driven past a construction site and spotted a worker rising high above the ground in a motorized basket, you’ve seen an aerial work platform in action. These machines are everywhere — on job sites, in warehouses, along highways, and on the sides of buildings — yet most people outside the industry have little idea what they are, how they work, or why they matter so much.
This guide breaks it all down, from the basics of what an AWP is to the different types available and why they’re considered essential tools in modern construction and maintenance.
What Is an Aerial Work Platform?
An aerial work platform (AWP) — sometimes called an elevated work platform (EWP) or aerial lift — is a mechanical device used to provide temporary access to elevated, otherwise-unreachable areas. In simple terms, it lifts workers (and their tools) off the ground safely and efficiently so they can do their jobs at height.
AWPs are powered machines. Unlike ladders or scaffolding, which are passive structures, aerial work platforms are motorized, mobile, and designed to reposition workers quickly without the time-consuming process of dismantling and rebuilding scaffolding. They give operators precise control over their vertical and horizontal position, making jobs faster, safer, and more cost-effective.
The term “aerial work platform” is an umbrella term that covers a wide range of equipment — from compact scissor lifts to towering boom lifts that can reach heights of 180 feet or more.
The Main Types of Aerial Work Platforms
Not all AWPs are the same. The right choice depends on the job, the terrain, and the height required.
1. Scissor Lifts
Scissor lifts get their name from the crisscrossed, accordion-style mechanism that raises and lowers the platform. They move strictly vertically and are ideal for work that requires a stable, wide platform directly above a fixed point — think ceiling installations, electrical work, or warehouse picking operations.
Scissor lifts are commonly used indoors and on smooth, flat surfaces. They come in electric models (for indoor use) and diesel-powered models (for rough outdoor terrain).
2. Boom Lifts
Boom lifts are the go-to machine when you need to reach up and out. Unlike scissor lifts, boom lifts use an extendable arm — the “boom” — to position the worker basket both vertically and horizontally, giving operators far more flexibility in tight or complex environments.
There are two main variants:
- Telescopic boom lifts extend in a straight line, like a telescope, and are best for reaching high points directly.
- Articulating boom lifts have jointed arms that can bend around obstacles, making them ideal for work on the sides of buildings or in spaces with obstructions.
JLG is one of the most recognized manufacturers of boom lifts in the world. If you’re working with JLG equipment and need replacement or maintenance components, JLG lift parts are available through specialized suppliers who stock the full range of components to keep your machines running at peak performance.
3. Vertical Mast Lifts
These are compact, single-person platforms that rise vertically. They’re lightweight, narrow, and perfect for tight indoor spaces like grocery stores, hospitals, or server rooms where a full-sized scissor lift wouldn’t fit.
4. Spider Lifts
Spider lifts are among the more unusual-looking AWPs. They feature stabilizing legs (hence the name) that extend outward to keep the machine balanced on uneven terrain. They’re popular for tree trimming, building maintenance, and work on sloped or rough ground where conventional lifts can’t safely operate.
5. Trailer-Mounted Lifts
These are AWPs mounted on trailers that can be towed to a job site. They’re often used for one-off jobs where purchasing or renting a full self-propelled unit isn’t practical. Utility companies and sign companies frequently use these for roadside work.
What Are AWPs Used For?
Aerial work platforms appear across a surprisingly wide range of industries. Their versatility is a big part of what makes them so valuable.
Construction is the most obvious use case. AWPs allow workers to safely access elevated areas for framing, roofing, facade installation, HVAC systems, and electrical work. On large commercial projects, you’ll often see multiple types of lifts operating simultaneously.
Building maintenance relies heavily on AWPs for window washing, exterior painting, gutter cleaning, and facade inspections. AWPs make these tasks not only safer but dramatically faster than traditional scaffolding.
Warehousing and logistics operations use scissor lifts and order pickers to move goods and workers to upper shelving levels with precision and speed.
Telecommunications and utilities depend on boom lifts and truck-mounted cranes to install and service power lines, cell towers, traffic lights, and signage.
Event production frequently uses AWPs to rig lighting, hang banners, and build stage structures for concerts, sporting events, and film shoots.
Forestry and landscaping crews use spider lifts and specialty units to safely prune and work around mature trees without the hazards of traditional climbing.
Why AWPs Matter in Construction and Maintenance
The importance of aerial work platforms goes far beyond simple convenience. They represent a fundamental shift in how we think about working at height — one driven by both safety imperatives and economic efficiency.
Safety
Before the widespread adoption of AWPs, working at height often meant improvised ladders, makeshift scaffolding, or risky manual hoisting. Falls remain one of the leading causes of workplace fatalities globally. AWPs dramatically reduce that risk by providing stable, enclosed platforms with guardrails, non-slip surfaces, and engineered weight limits. Modern machines also feature automatic leveling, outrigger systems, and tilt sensors that prevent operation on unsafe slopes.
Speed and Efficiency
A scissor lift can be deployed and operational in minutes. Scaffolding for the same job might take hours or even days to erect. AWPs let crews move freely and reposition as needed, turning multi-day tasks into single-day efforts.
Cost-Effectiveness
Labor is expensive. When workers can reach their work area quickly, safely, and without the overhead of scaffold erection and dismantling, project timelines shrink and labor costs fall. For contractors, this is a direct competitive advantage.
Reach and Versatility
Modern AWPs can reach heights that would be impractical to scaffold safely. Telescopic boom lifts routinely access points 120 to 150 feet above ground, while some specialty units exceed 180 feet. That kind of reach, combined with precise positioning, opens up project possibilities that simply weren’t feasible with traditional methods.
Keeping AWPs Running: The Role of Quality Parts
Like any heavy equipment, aerial work platforms require regular maintenance to stay safe and functional. Hydraulic systems, drive motors, control panels, and safety sensors all need periodic inspection and occasional replacement. Using quality, manufacturer-compatible components isn’t just good practice — it’s often a regulatory and safety requirement.
For construction and maintenance professionals working with aerial lifts, sourcing reliable parts quickly can be the difference between a day’s delay and a week-long shutdown. Intella Parts is an example of a supplier dedicated to providing AWP components — including parts for JLG, one of the industry’s most trusted lift manufacturers — ensuring machines spend more time working and less time waiting for repairs.
Final Thoughts
Aerial work platforms are the unsung workhorses of the modern built environment. They make it possible to construct skyscrapers, maintain bridges, service power grids, and keep the infrastructure of everyday life running — all with a level of safety and efficiency that previous generations of workers couldn’t have imagined.
Whether you’re new to the industry, considering renting a lift for a project, or simply curious about the machines you see on job sites every day, understanding what AWPs are and why they matter is the first step toward appreciating just how much they shape the world around us.
