Are Scissor Lifts Considered Aerial Lifts?

Yes, scissor lifts are considered a type of aerial lift or mobile elevating work platform (MEWP). Aerial lifts include machinery used to safely lift workers vertically, such as scissor lifts, boom lifts, aerial work platforms, aerial ladders, and articulating boom lifts.

Scissor lifts function through a scissor mechanism and are commonly used in construction works, like installing power lines and maintenance tasks to access high heights safely, as required by regulations like ANSI and OSHA. They allow workers to conduct jobs in various locations, including outdoor uses and rough terrains.

Comparing Scissor Lifts to Aerial Lifts

Both scissors and aerial lifts aim to elevate workers and equipment to height safely. Mobile elevating work platforms, or MEWPs, protect workers from fall hazards and allow jobs to be performed from an elevated work area or platform. Some critical similarities between scissor lifts and other types of aerial lifts include:

Similarities in Functionality and Purpose

Scissor lifts and other aerial lifts like boom lifts, aerial work platforms, aerial ladders, and articulating boom lifts all function to lift workers vertically using a lifting mechanism moves, whether the scissor mechanism in scissor lifts or articulating booms in boom lifts.

They aim to provide safe access to heights required for jobs like installing power lines, conducting maintenance of overhead hazards or outdoor signage, and other construction works.

Scissor lifts and aerial lifts both allow working at height in compliance with the safety regulations of ANSI and OSHA. Their mobile scaffold design suits them for both level and rough terrains.

Differences in Design and Operation

While scissors and aerial lifts have similarities in their purpose of safely lifting workers to height, they differ in design and operation. Scissor lifts function through a scissor mechanism consisting of crisscrossing support legs resembling scissors that elongate to raise the platform vertically.

They are often electric-powered and suitable for indoor and outdoor use in level and rough terrains. On the other hand, boom lifts use articulating or extending boom arms to lift the work platform, allowing greater horizontal reach. Boom lifts may be electric, fuel, or hydraulic-powered and used following manufacturer instructions for tasks like servicing overhead lines and hazards. Both are operated by trained personnel in compliance with safety standards to prevent accidents at worksites.

Regulatory Classifications

Safety regulations set by authorities like ANSI and OSHA classify mobile elevating work platforms (MEWPs) like scissor lifts and boom lifts into different types depending on their design and use.

These include MEWP Group A for self-propelled scissor lifts used indoors and outdoors and Group B for larger boom lifts and aerial work platforms used in construction works.

Proper operator training and following manufacturer instructions are important per OSHA standards when using MEWPs to handle materials safely and prevent accidents from risks like tipping over on uneven terrains or working at unsanctioned locations like near power lines. Regulations aim to protect lift workers and provide safe work platforms and fall protection when working at height.

Benefits Of Using Scissor Lifts

Here are some benefits of using scissor lifts, including:

• Enhanced Safety Measures: Scissor lift operators benefit from adherence to American National Standards Institute (ANSI) regulations, ensuring compliance with scissor lift safety protocols. With features such as guardrail systems and manufacturer-provided training, operators can work safely at elevated heights, minimizing the risk of accidents.
• Increased Efficiency: Utilizing scissors and aerial lifts provides a more efficient alternative to traditional methods of accessing elevated workspaces. These lifts offer versatile lifting mechanisms that move vertically, horizontally, and in various directions, allowing operators to navigate different locations and easily save time and effort.
• Enhanced Accessibility: Scissor lifts and aerial work platforms enable operators to easily access elevated work areas such as vertical towers and boom platforms. This accessibility is particularly advantageous in construction settings where safely reaching an elevated platform location is essential for completing tasks efficiently.
• Improved Flexibility: Scissor lifts come in various classifications and types, including an electric model and mobile elevated work platforms (MEWPs), offering flexibility in choosing the right equipment for specific work locations and requirements. This adaptability ensures operators can efficiently maneuver in different work environments, indoors or outdoors.
• Optimal Work Environment: Scissor lifts contribute to a safer and more ergonomic work environment by providing a stable platform for operators to perform tasks without the need to lean or compromise their safety. Features such as small buckets and platform locations further enhance the efficiency and comfort of operators while working at height.

Safety Considerations When Using Scissor Lifts

Prioritizing safety when working with heavy equipment like aerial lifts is crucial. These mobile elevating work platforms enable workers to access job sites at heights and present potential hazards if not operated properly.

Aerial lifts such as scissors and boom lifts can expose operators and workers to fall risks, tipping accidents, and other dangers if safety protocols are not followed carefully.

Common Safety Hazards Associated With Aerial Lifts

To protect lift workers, it is essential to be aware of potential safety hazards when operating aerial lifts like scissors and boom lifts. Hazards include tipping over on uneven terrain or near drop-offs, especially in rough terrain conditions or high wind speeds.

Overloading the platform or moving the equipment in the stowed position can also lead to stability issues. Working near overhead power lines and other overhead hazards like traffic requires proper safety training and following traffic control measures for protection.

Fall hazards are also present, requiring guardrail systems, tied-off attachments, and fall protection per OSHA regulations. Crushing injuries may occur from moving parts of the lifting mechanism. Therefore, operators must provide training per manufacturer instructions and only operate MEWPs on level surfaces within the rated capacity.

Specific Safety Concerns Related to Scissor Lifts

Some safety hazards specific to scissor lifts include tipping over on uneven or sloped terrain, which concerns rough terrain scissor lifts working outdoors. Operators must receive proper training per manufacturer instructions and know the lift’s load capacity and rated working conditions.

Scissor lifts may also present crushing hazards between the scissor arms or legs during operation if safety procedures are not followed. Proper fall protection, such as a guardrail system, is essential for scissor lifts in outdoor environments or near drop-offs.

Safety Regulations and Best Practices for Both Types of Lifts

Regulatory standards set by authorities like ANSI and OSHA guide the safe operation of aerial and scissor lifts. Provisions include following traffic control measures, avoiding moving lifts near overhead power lines, and other equipment overhead hazards. OSHA requirements, such as fall protection attachments and guardrails, must be in place.

Lift workers should also receive safety training on lift capacities, stabilizing on uneven terrain, avoiding leaning outside the platform, and handling materials safely per manufacturer instructions. Mobile elevating work platforms must only be used by trained operators in compliance with regulations to protect workers and prevent accidents across various job sites and industries.
