Boom Lift vs Scissor Lift: Which Aerial Lift is Right for Your Job?

Choosing the right aerial lift is critical for your project’s efficiency, safety, and budget. Whether tackling high-rise construction, managing warehouse inventory, or performing facility maintenance, the equipment has a profound impact on success.

The two most common aerial lifts are boom lifts and scissor lifts; while both elevate workers, their functions differ significantly. The main difference is that boom lifts offer horizontal reach, while scissor lifts move vertically with more stability. The incorrect selection of lift equipment results in expensive delays and safety risks.

When deciding whether to use a scissor lift or a boom lift, it's not a matter of technical specifications; it's a matter of how and where you're going to use the equipment. Each lift is designed for specific scenarios, and understanding the difference will allow you to choose the safest and most efficient option.

Scissor Lifts Use Cases

• Moves only straight up and down, supported by a crisscrossed (scissor-like) mechanism for maximum stability.

• Best for indoor or flat-surface tasks where vertical height is the main requirement.

• Common use cases:

  • Installation or maintenance of ceiling-mounted lights and electrical devices.

  • Painting or cleaning of flat walls and ceilings.

  • Warehouse stocking, retrieval, or storage management.

  • Construction or maintenance tasks requiring multiple workers on the same platform.

Boom Lifts Use Cases 

• Features a hydraulic arm that extends both horizontally and vertically, offering greater reach and maneuverability.

• Ideal for outdoor, uneven, or complex work environments where you need to move up, over, or around obstacles.

• Common use cases:

  • Maintenance and installation of rooftop AC units or mechanical equipment.

  • Cleaning windows on tall or irregularly shaped buildings.

  • Outdoor construction or maintenance around trees, signs, or power lines.

  • Bridge or industrial site inspections where access points are restricted.

When your work requires more than vertical lift, a boom lift is the way to go. They're ideal for outdoor applications, construction sites, and difficult access situations. But boom lifts are different.

Boom lifts exist in articulating and telescopic styles, both built for varying reach demands.

• Articulating Boom Lifts: Also referred to as "knuckle booms," these lifts have several joints in their arm. This configuration gives them amazing agility, so they can drive around obstacles such as trees or the structures of buildings. They perform well in tight spaces, such as painting intricate architectural features or maintenance in industrial plants.
• Telescopic Boom Lifts: Telescopic Boom Lifts: Also referred to as "stick booms or straight boom lifts," these models have a straight, extendable arm providing maximum horizontal outreach. They are the masters of height and distance, perfect for high-rise building work, bridge inspection, or any job that requires reaching across big, open spaces without obstruction.
• Crawler Boom Lift: These types are built for tough terrain. Instead of wheels, they use rubber tracks, similar to those on a tank, which provide superior stability and traction on mud, sand, snow, and uneven ground. Their low ground pressure makes them ideal for soft or sensitive surfaces where wheeled lifts might sink or lose control. Crawler models come in both articulating and telescopic configurations, offering flexibility without sacrificing rugged performance. They're the go-to solution for outdoor jobs in rough, remote, or unfinished sites where traction and stability are critical.

Boom lifts have no equal in terms of reach, with certain models reaching more than 185 feet in the vertical plane. The majority are made for hard outdoor use, featuring 4-wheel drive, oscillating axles, and mud-type tires with aggressive tread for mud, inclines, and rough surfaces.

However, their platform capacity is typically less than that of scissor lifts, usually supporting a single or two workers with an average capacity of approximately 500 lbs.

A boom lift is excessive for mere vertical tasks on a flat surface. For simple indoor work such as warehouse applications, the scissor lift's sophistication, increased price tag, and bigger footprint are not needed and are wasteful.

For applications where a stable, high-working platform is needed for employees and materials with no horizontal reach, the scissor lift is the best choice.

Scissor lifts also exist in models designed specifically for certain environments.

• Electric Scissor Lifts: Indoor standard, electric-powered scissor lifts are quiet and zero-emission, safe in enclosed environments such as warehouses, hospitals, schools, and retail outlets. Non-marking tires ensure floor protection, and their compact shape facilitates easy movement through tight aisles.
• Rough Terrain (RT) Scissor Lifts: Designed for use outside, these lifters are most often diesel-powered with four-wheel drive, heavy-duty tires, and added stability. They traverse uneven surfaces, mud, and slopes that are prevalent on construction sites for applications such as installing siding or outside signage.

Electric scissor lifts perform best in indoor environments. Their big, rectangular working platform allows for ample room for several workers, tools, and materials, minimizing trips and enhancing productivity. Their straightforward, only-vertical operation is simple to operate and inherently stable.

Outside of warehousing, scissor lifts are utilized in retail for display setup and stocking. On movie sets, they offer working platforms for crews. Indoor sports arenas utilize them for the upkeep of scoreboards and ceiling equipment.

The wrong lift can be an expensive mistake. Here are the most frequent errors and how to avoid them.

This is mistake number one. Some select a scissor lift based on platform size and lower price, then realize that they have to reach around an obstacle. Always determine maximum height and measure horizontal outreach requirements. Keep in mind, "working height" is usually 6 feet above "platform height."

Operating an electric slab scissor lift outdoors is dangerous. Its wheels are intended for smooth surfaces and will become bogged down in mud or break up on uneven ground, posing a tip-over hazard. Always ensure the lift's terrain capacity matches your work site.

Never operate a diesel lift in an indoor area that is not well ventilated. Diesel engines produce deadly carbon monoxide, and in confined spaces, that can be fatal. For indoors, only an electric lift is safe.

A lower upfront cost can result in increased long-term costs. An under-spec'd lift may require the need to rent a second machine, or result in efficiency losses costing more in labor and time than are being saved on the front-end rental.

Take into consideration the weight of workers, tools, and materials. Overloading the platform is one of the leading causes of accidents. Refer to the manufacturer's recommended load capacity.

The sticker price is only the tip of the iceberg. Real cost includes maintenance, gasoline, and safety compliance.

Although scissor lifts tend to be cheaper to buy, optimal ROI is realized from selecting the appropriate machine for the task. A higher-cost boom lift that finishes a complicated task in less time provides a superior return compared to a lower-cost scissor lift that is incapable of doing the job right.

In the United States, OSHA’s Aerial Lifts FactSheet and Aerial Lifts e-Tool state that only trained and authorized personnel may operate aerial lifts such as boom lifts and scissor lifts.

Employers must provide instruction on hazards, safe use, inspections, and manufacturer guidelines, followed by hands-on practice and evaluation. All training and authorization must be documented to meet compliance, with industry best practices guided by ANSI/SAIA A92 standards.

For scissor lifts, typical injuries are tip-overs (from an uneven surface or overloading) and falls. For boom lifts, there are risks of electrocution from power cables and crushing injuries from the large range of motion. Appropriate training and on-site evaluation can reduce these hazards.

Electric lifts are fuel-efficient but need to be charged. Diesel boom lifts provide more power and runtime but consume more fuel or require more maintenance, and cannot be used indoors.

Boom lifts and scissor lifts are essential across multiple sectors, providing safe, elevated access for tasks that require height, precision, and efficiency. Below are the following industries that rely on one or both of these lifts to carry out their operations effectively.

In building construction, an outdoor telescopic boom lift is needed to do roofing or steel frame erection, which requires high elevation and long reach. Inside, an electric scissor lift is ideal for drywalling, suspending materials, and laborers on its sturdy platform.

The scissor lift's home environment, the warehouse, is utilized for receiving inventory, picking orders, and facility upkeep, offering protected and efficient elevated shelf access.

This is strictly boom lift country. Articulating or telescopic boom lifts, sometimes insulated, are needed to safely place utility workers close to high-voltage wires or telecom cables. A scissor lift is not capable of that kind of reach or agility.

For routine maintenance in big buildings such as airports or schools, both lifts find their use. Scissor lifts are used for tasks such as replacing light bulbs or cleaning high-up windows, while boom lifts may be required for exterior maintenance or trimming a tree.

Purchasing or renting a boom lift or scissor lift for the first time can be challenging without the right guidance. The expert tips below will help you choose the right equipment, avoid costly mistakes, and ensure a safe, efficient experience from day one.

Measure your top reach point physically. Subtract 6 feet for "working height." Horizontally check from the base position of the lift for obstructions requiring outreach, meaning a boom lift.

Inside confined, congested areas, favor a small, very maneuverable lift (articulating boom or compact electric scissor lift). When heavy materials and several workers are being lifted, platform size and weight capacity are priorities.

Don't spend money on unnecessary features. For level, indoor use, a heavy-duty rough-terrain version is extravagant. A careful site evaluation can avoid renting or purchasing an over-furnished machine.
