This article overviews scissor lifts, their uses, and important safety considerations. Scissor lifts are versatile aerial work platforms commonly used in construction and maintenance jobs.

From selecting the right lift model to operating safely at height, this guide covers critical aspects of working with these lifts to complete overhead tasks in compliance with regulations.

What Is a Scissor Lift?

A scissor lift, also known as an aerial work platform, is a mechanical device that provides temporary access to elevated working areas for maintenance and construction tasks. It consists of a platform supported by crisscrossing braces known as scissors that expand and contract, allowing the lift to reach varying heights required for overhead jobs.

Scissor lifts are widely used in construction, facilities maintenance, and utilities to complete projects at height efficiently.

How Does a Scissor Lift Work?

A scissor lift gets its name from its unique lifting mechanism, which uses a system of crisscrossing metal braces known as scissors to raise and lower the platform. As compressed air or an electric motor activates, the scissors expand, folding and lifting the platform upwards. When retracted, the platform descends.

This scissoring action allows scissor lifts to safely reach various heights, from just a few feet off the ground to over 50 feet high, depending on the model, making them invaluable for indoor and outdoor construction, facility maintenance, and other overhead jobs that require temporary elevated access.

What Are the Different Types of Scissor Lifts?

Here are different types of scissor lifts, including:

• Electric scissor lifts are battery-powered and suitable for indoor use and job sites without external power.
• Rough terrain scissor lifts are Diesel- or gas-powered lifts with large tires or tracks for use on uneven or unpaved terrain.
• Hydraulic scissor lifts: Lifts that use hydraulic fluid pressure rather than electricity to power the lifting mechanism.
• Self-propelled scissor lifts: Wheeled lifts that can be driven from the platform controls to reposition around a site.
• Boom lifts: Lifts with an extendable working platform on the end of an articulating or telescoping boom for even greater reach.
• Outdoor scissor lifts: Weather-resistant lifts for outdoor construction and facilities work in all weather conditions.

What Are the Main Applications of Scissor Lifts?

Some typical applications of scissor lifts include maintenance, construction, installation, and painting. They are often used in manufacturing facilities, warehouses, and other industrial settings to service machinery, change lightbulbs, install equipment, and apply coatings to tall structures.

Scissor lifts are also widely used on construction sites to install siding, hang drywall, waterproof, and insulate. Their portable, elevated platform enables workers to quickly and safely complete overhead jobs.

What Are the Safety Precautions When Using a Scissor Lift?

Scissor lift operators must be adequately trained in safety procedures and wear the necessary personal protective equipment. This includes fall protection, such as safety harnesses and guardrails, to prevent falls from heights.

The lift capacity must also be followed to avoid overloading or tipping accidents. Operator training per OSHA and ANSI A92 guidelines helps ensure safe movement and positioning of the lift to avoid contact with power lines or other hazards. Adhering to manufacturer instructions and warnings further reduces risks on the job site.

How High Can a Scissor Lift Extend?

The maximum height that a scissor lift can extend depends on the specific model. Many electric scissor lifts commonly reach 40 feet, allowing access to multi-story buildings to install and service HVAC equipment and windows.

Larger diesel-powered rough terrain scissor lifts may be able to lift to greater heights of over 50 feet, which helps complete construction projects and perform maintenance on tall structures, power lines, and wind turbines safely under proper training and safety protocols.

What Are the Scissor Lift Weigh Capacities?

Scissor lifts’ weight capacity or lift capacity can range from 500 pounds or less for smaller electric models to over 2,500 pounds for larger heavy-duty rough terrain scissor lifts. This allows them to safely carry one or several workers with their tools and materials.

Proper weight distribution within the platform is essential to avoid stability issues. Operators must never exceed the rated load capacity specified by scissor lift manufacturers and ANSI safety standards to ensure safe operation at any working height.

Are Scissor Lifts Suitable for Outdoor Use?

Yes, many scissor lifts are suitable for outdoor use on construction sites and other outdoor job applications. Rough terrain scissor lifts with larger tires or tracks are especially well-suited to operate on uneven or unpaved terrain, allowing work to be performed safely in all weather conditions.

Outdoor SKYJACK scissor lifts are designed to withstand wind, rain, and sunlight to ensure reliable performance in outdoor environments. Proper training is still required as wind speeds and terrain variations present additional safety considerations for operators working outdoors at heights.

How Do You Transport a Scissor Lift?

Scissor lifts can be transported to job sites using truck beds or trailers with hydraulic lifts or ramps for easy loading and unloading. Electric scissor lifts are often small enough to be driven onto transport vehicles under their power. Larger rough terrain scissor lifts may require a forklift or crane for loading and offloading.

Proper tie-down straps should always be used to secure the electric lift firmly during transport. Following manufacturer recommendations helps ensure the safe transportation of these valuable aerial work platforms between construction sites.

What Are the Maintenance Requirements for Scissor Lifts?

Proper maintenance is essential to ensure scissor lifts are safely operating as intended. Routine scissor lift inspections should check for hydraulic fluid leaks, worn hoses or cables, and damaged electrical components. Batteries require regular testing and may need replacement.

Greasing pivot points helps reduce wear and tear on the lifting mechanism. Following an inspection checklist ensures all functions perform as specified by manufacturers. Per the operator manual, repairs should only be made by trained technicians. This helps prevent workplace accidents and protects workers at heights.

Can Scissor Lifts Be Operated on Uneven Surfaces?

While many electric scissor lifts are designed for level indoor surfaces, rough terrain scissor lifts can safely operate on uneven or unpaved terrain thanks to their larger tires or tracks. This allows construction and maintenance work to continue smoothly even if a job site features uneven ground conditions.

Of course, proper operator training is still required as uneven surfaces present additional safety considerations. Operators must avoid surfaces with deep ruts, soft earth, steep slopes, or drop-offs that could compromise the stability of these aerial work platforms.

Are There Any Regulations or Standards Governing the Use of Scissor Lifts?

Yes, some necessary regulations and standards govern the proper use of scissor lifts to ensure workplace safety. OSHA provides guidelines for aerial work platforms that must be followed on construction sites. ANSI A92 standards set lift design, operation, and safety system specifications.

Operator training programs help workers learn to operate aerial equipment per these requirements safely. Following manufacturer instructions also helps ensure lifts are utilized as intended. Compliance protects operators and workers below and prevents accidents at height.

What Are the Main Components of a Scissor Lift?

The main components of a scissor lift include the platform, lifting mechanism, power source, and safety features. The platform provides a stable work area for workers and tools. The lifting mechanism, typically comprised of crisscrossing hydraulic or electric braces, raises and lowers the platform.

Electric scissor lifts often run on battery power, while diesel or gas engines may also be the power source. Safety features like guardrails, toeboards, and fall protection anchors help ensure proper fall protection as specified in OSHA scissor lift requirements.

Can Scissor Lifts Be Used for Overhead Work?

Yes, scissor lifts are commonly used for overhead work when other means are not practical or safe. Their elevated platform enables workers to install ceiling tiles or lights, paint, and repair HVAC systems at height. Proper fall protection, such as guardrails and a safety harness, is still required per OSHA regulations when working overhead.

Operators must also pay attention to maximum height limits and ensure the boom lift is on level ground to maintain stability for any overhead reach. Following safety protocols helps prevent falls and injuries.

How Do I Choose the Right Scissor Lift for My Project?

When choosing the right scissor lift for a construction or maintenance project, several factors should be considered. The working height and lift capacity should accommodate your height needs and the number of workers/tools.
