Ever wondered about the differences between scissor lifts vs. aerial lifts? Both types of forklifts are essential to the modern construction and logistics industries. The key difference between these lifts lies in their functionality. A scissor lift is a type of aerial lift that allows workers to complete tasks at heights. But, the lift moves only up and down. Comparatively, an aerial lift can move in different directions. It also comes in many forms.
Scissor Lift vs. Aerial Lift: What&#;s the Difference?
Aerial lifts and aerial scissor lifts are more alike than they are different. Even aerial work platform workers often fail to understand what makes each piece of equipment unique. Ultimately, the differences between scissor lifts vs. aerial lifts come down to OSHA definitions.
OSHA defines an aerial lift as a machine used to lift workers. An aerial lift lets operators complete tasks at heights. In addition, the machine should only be used by an OSHA-approved operator. Otherwise, an unlicensed aerial lift operator risks operational or maintenance errors that can lead to accidents, injuries, and fatalities. Aerial lifts are frequently used for construction, maintenance, by those working on power or lines, while fighting fires in tall structures, for window washing, during safety inspections, and for orchard and tree care.
A scissor lift is similar to a standard aerial lift. This type of lift can move workers and equipment vertically. As such, a scissor lift enables operators to safely access work areas that commonly require a ladder, tower, or scaffolding. Professionals rely on scissor lifts to repair signs, clean gutters, provide safe access to high shelves, and for routine maintenance chores.
It pays to know the similarities and differences between scissor and aerial lifts. Regardless of the type of lifts used across your business, your workers need OSHA-approved certification training, too. This training verifies that your employees know how to use different types of aerial lifts. It also confirms that your workers can do their part to identify scissor and aerial lift hazards and address them right away.
What is an Aerial Lift?
OSHA&#;s aerial lift definition is the same as the one from the American National Standards Institute (ANSI), which considers the following vehicle-mounted rotating and elevating platforms as aerial lifts:
&#; Vertical towers
&#; Aerial ladders
&#; Articulating boom platforms
&#; Any combination of the above
Aerial lifts, or boom lifts, are classified as vehicle-mounted devices used to elevate personnel. They can lift workers both vertically and horizontally to reach exterior building structures, windows, trees, and power lines. They can be articulated to reach up and over structures, as well as access the top of roller coasters. The difference between an aerial lift and a scissor lift is that scissor lifts can only extend horizontally, and do not have the same reach power.
Think of aerial lifts as a more versatile elevated work platform. Aerial lifts, unlike aerial scissor lifts or vertical scissor lifts, are typically used outdoors. However, they&#;re also used in some indoor facilities, such as heavy equipment manufacturing centers.
What is a Scissor Lift?
Just what is a scissor lift, exactly? They do not fall within any of the above categories of aerial lifts, nor are there any OSHA provisions exclusive to scissor lifts. They do, however, meet the definition of a scaffold. Unfortunately, if you look at the general requirements for scaffolds (§.451), you won&#;t find scissor lifts mentioned. Anywhere on the page. Luckily, OSHA has made some improvements with their Scaffolding eTool. This page on the OSHA website makes it easier to understand what is a scissor lift and where it falls within the standards. It gives industry professionals some helpful background information on what makes a scissor lift.
According to OSHA, scissor lifts are &#;mobile supported scaffold work platforms used to safely move workers vertically and to different locations in a variety of industries including construction, retail, entertainment, and manufacturing.&#; Unlike aerial lifts, scissor lifts can only move vertically, directly above the base. It&#;s the recognizable criss-cross style beams that move the lift platform straight up and down.
All scissor lifts are considered scaffolding, whether it&#;s a vertical scissor lift or aerial scissor lift.
Additional differences between what is a scissor lift and an aerial lift are the use of fall protection. OSHA requires that operators use body harnesses and lanyards on aerial lifts at all times, but these personal protection tools aren&#;t requirements for scissor lifts. As long as there are functioning guardrails present, scissor lift operators don&#;t need to wear harnesses while on the platform. This applies to aerial scissor lifts and vertical scissor lifts.
Why Use a Scissor Lift vs. an Aerial Lift?
Both of these unique tools come with their own pros and cons. Scissor lifts are simple to use and easy to move from one location to the next. They&#;re also easy to operate and can be used in diverse work environments &#; including the outdoors. Scissor lifts have bigger platforms, allowing more than one person to safely work on the lift at the same time. They&#;re cheaper than aerial lifts and are easier to store.
Aerial lifts, on the other hand, can reach up and around structures to access even the most difficult of areas. They can work at heights of 180 feet or greater. They allow workers to perform their duties safely, even on rough or uneven terrain. Small platforms mean operators can work in tight areas, and the ability to extend long distances horizontally allows for even more versatility.
The Importance of Aerial Lift and Scissor Lift Safety
Perhaps the most important difference in scissor lifts vs. aerial lifts is their operation. Each lift has unique safety standards that operators must follow in order to prevent accidents. A little education can go a long way in keeping workers safe on the job.

All are aerial lifts, defined by OSHA as &#;any vehicle-mounted device used to elevate personnel.&#;
The agency says aerial lifts &#;may be powered or manually operated, and are considered to be aerial lifts whether or not they can rotate around a primarily vertical axis.&#;
Even though the lifts &#;have replaced ladders and scaffolding on many jobsites due to their mobility and flexibility,&#; several hazards are associated with their use. Among them: falls from height, objects falling from lifts, tip-overs and electric shock/electrocution (often caused by contact with power lines).
Associate Editor Alan Ferguson discusses this article on the September episode of Safety+Health's &#;On the Safe Side&#; podcast.
Here are five facts about aerial lifts to help ensure they&#;re used safely.

That&#;s according to OSHA. In an August letter of interpretation, the agency states that its standard on aerial lifts in construction (.453) is based on an American National Standards Institute consensus standard: ANSI A92.2-.
&#;Therefore, the requirements in .453 apply to equipment identified in that ANSI consensus standard as aerial lifts. The ANSI standard definition includes the following vehicle-mounted elevating and rotating work platforms: &#;extensible boom platforms,&#; &#;aerial ladders,&#; &#;articulating boom platforms,&#; &#;vertical towers,&#; and &#;a combination of any of the above,&#;&#; writes Russell B. Swanson, former director of OSHA&#;s Directorate of Construction.
Scissor lifts are considered scaffolds and, because they&#;re mobile, &#;the specific requirements for mobile scaffolds in the scaffold standard (.452[w]) must be met.&#;

That&#;s according to A92 Committee Chair Joshua Chard, who adds that an aerial lift is &#;generally understood to be equivalent to the defined term &#;mobile elevating work platform,&#; or MEWP.&#; An &#;aerial device,&#; meanwhile, is a &#;chassis (generally a truck) mounted elevating work platform.&#;
The A92.20, A92.22 and A92.24 standards apply to MEWPs, while A92.2 applies to aerial devices.
OSHA regulates aerial lifts under .67, .269(p), .453, .21 and .502.
The Scaffold & Access Industry Association has served as secretariat for the A92 standards since .

Only trained and authorized workers are permitted to operate an aerial lift, per OSHA. That training should include:
Retraining is required when an incident occurs while using an aerial lift, workplace hazards involving an aerial lift are discovered, a different type of aerial lift is being used or if an employer observes a worker operating an aerial lift improperly.
The ANSI/SAIA standard on training requirements for MEWPs is A92.24-. Training requirements for aerial devices are found in OSHA&#;s .67 and .453, as well as the ANSI/SAIA A92.2 standards.

OSHA&#;s Subpart L, which covers aerial lifts and scaffolds, requires employers to have &#;each employee who performs work while on a scaffold trained by a person qualified in the subject matter to recognize the hazards associated with the type of scaffold being used and to understand the procedures to control or minimize those hazards.&#;
The ANSI/SAIA A92 standards differentiate between operators and &#;occupants.&#; An occupant is, for example, someone who&#;s on a work platform but not at the controls.
&#;Sometimes the work may require you to have an assistant,&#; said Mike Kassman, director of OSHA and disaster response training at CPWR &#; The Center for Construction Research and Training. &#;He or she should also have an orientation to that aerial lift or scissor lift.&#;

OSHA requires everyone working from an aerial lift to have a personal fall protection system.
&#;Employers must ensure that employees tie off at all times when working from an aerial lift,&#; the agency writes in an August letter of interpretation.
When workers are 6 feet or higher above a lower level, personal fall arrest systems must comply with .502(d) in Subpart M.
In the general industry standards, a fall arrest or travel restraint system must meet the requirements of Subpart I. Personal fall arrest systems need to be rigged so that workers don&#;t fall more than 6 feet and make contact with a lower level.
Body belts, as of January , are no longer an acceptable part of a personal fall arrest system, according to .453(b)(2)(v). However, the use of a body belt as part of a tethering system or restraint system is acceptable and regulated under .502(e), OSHA says.
OSHA&#;s and standards require that employees &#;always stand firmly on the floor of the basket, and shall not sit or climb on the edge of the basket or use planks, ladders or other devices for a work position.&#;
