Safety is paramount when it comes to the design, installation, and maintenance of platform lifts and stairway chairlifts. These devices provide essential accessibility solutions for individuals with mobility challenges, allowing them to navigate buildings and overcome architectural barriers. To ensure the highest level of safety and reliability, the American Society of Mechanical Engineers (ASME) has developed the A18.1 Safety Standard for Platform Lifts and Stairway Chairlifts.
At Mobility123, a leading elevator company in New Jersey, we understand the importance of adhering to the ASME A18.1 standard. This article aims to provide architects, builders, and elevator industry professionals with a comprehensive overview of the standard, highlighting its significance and offering best practices for implementation.
Key Definitions:
Before diving into the specifics of the ASME A18.1 standard, it's essential to understand some key terminology. Platform lifts are mechanical devices designed to transport a person in a standing or seated position between two or more levels, typically in a vertical or inclined direction. Stairway chairlifts, on the other hand, are mechanical devices designed to transport a seated person up and down a stairway.
The ASME A18.1 standard distinguishes between public and private residence applications. Public applications refer to platform lifts and stairway chairlifts installed in buildings accessible to the general public, such as commercial buildings, schools, and healthcare facilities. Private residence applications are those installed in private homes or residences.
Other important terms defined in the standard include runway enclosures, ramps, safeties, and governors. These components play critical roles in the safe operation of platform lifts and stairway chairlifts.
Equipment Covered by ASME A18.1:
The ASME A18.1 standard covers a range of equipment designed to provide accessibility solutions for individuals with mobility challenges. This includes:
- Inclined Stairway Chairlifts: These devices are designed to transport a seated person up and down a stairway, following the incline of the stairway.
- Inclined Platform Lifts: These lifts are designed to transport a person in a standing or seated position along an inclined plane, typically alongside a stairway.
- Vertical Platform Lifts: These lifts are designed to transport a person in a standing or seated position vertically between two or more levels.
It's important to note that the ASME A18.1 standard does not cover equipment such as elevators, escalators, moving walks, material lifts, dumbwaiters, personnel hoists, or manlifts. These devices are covered by other ASME standards, such as ASME A17.1 for elevators and escalators.
Understanding the Difference: ASME A18.1 and ASME A17.1 Elevator Codes
By clearly defining the scope of the standard, ASME A18.1 ensures that manufacturers, installers, and owners of platform lifts and stairway chairlifts have specific guidelines to follow, promoting safety and reliability in the industry.
Significant Requirements for Platform Lifts:
The ASME A18.1 standard outlines several key requirements for platform lifts to ensure their safe and reliable operation. Some of the most significant requirements include:
- Runway Enclosures, Ramps, and Pits: The standard specifies requirements for runway enclosures, which protect users from the moving components of the lift. It also covers the design and installation of ramps and pits, ensuring safe access to the platform.
- Platform Requirements: The standard dictates minimum and maximum platform sizes, as well as requirements for platform floors, doors, and gates. It also specifies the location and design of operating controls, ensuring ease of use for individuals with disabilities.
- Capacity, Speed, and Travel Limits: ASME A18.1 sets limits on the rated load, speed, and travel distance of platform lifts. These limits are based on the type of application and the specific requirements of the installation site.
- Safety Devices: Platform lifts must be equipped with a range of safety devices, including safeties and governors. Safeties are mechanical devices that stop and hold the platform in case of an overspeed condition or suspension failure. Governors monitor the speed of the platform and activate the safeties if necessary.
- Electrical Equipment and Wiring: The standard provides requirements for the installation of electrical equipment and wiring, ensuring the safe and reliable operation of the lift's electrical components.
By adhering to these requirements, manufacturers, installers, and owners can ensure that platform lifts provide a safe and reliable means of vertical transportation for individuals with mobility challenges.
Significant Requirements for Stairway Chairlifts:
ASME A18.1 also provides specific requirements for stairway chairlifts to ensure their safe and reliable operation. Some of the most significant requirements include:
- Seat and Footrest Specifications: The standard dictates the minimum and maximum seat dimensions, as well as requirements for footrests and armrests. These specifications ensure that users can comfortably and safely use the chairlift.
- Capacity, Speed, and Angle Limits: ASME A18.1 sets limits on the rated load, speed, and angle of incline for stairway chairlifts. These limits are based on the specific requirements of the installation site and the needs of the user.
- Safety Devices: Stairway chairlifts must be equipped with safety devices, such as seatbelts, to ensure the safety of the user. The standard also requires that chairlifts have a means of stopping and holding the chair in case of an overspeed condition or suspension failure.
Private Residence Applications:
The ASME A18.1 standard recognizes that platform lifts and stairway chairlifts installed in private residences may have different requirements than those installed in public buildings. As such, the standard provides specific guidelines for private residence applications.
For vertical platform lifts installed in private residences, the standard allows for smaller platform sizes and reduced clearances. It also permits the use of a self-closing door or gate at the upper landing, rather than requiring a fully enclosed runway.
Similarly, for inclined platform lifts and stairway chairlifts installed in private residences, the standard provides specific requirements for platform size, ramps, and safety devices. These requirements are tailored to the unique needs of residential applications, while still ensuring the safety and reliability of the equipment.
Inspection and Testing Requirements:
To ensure the ongoing safety and reliability of platform lifts and stairway chairlifts, the ASME A18.1 standard mandates regular inspections and tests. These requirements are divided into four categories:
- Routine Inspections and Tests: These inspections and tests are performed at regular intervals, typically every six months for public applications and routine maintenance for for private residence applications. They include a visual inspection of the equipment, as well as functional tests of safety devices and operating controls.
- Periodic Inspections and Tests: These inspections and tests are performed at longer intervals, typically every one to five years, depending on the specific requirement. They include more in-depth inspections of the equipment's components, such as safeties, governors, and hydraulic systems.
- Acceptance Inspections for New Installations: Before a newly installed platform lift or stairway chairlift can be put into service, it must undergo a comprehensive acceptance inspection and test. This ensures that the equipment meets all applicable codes and standards and is safe for public use.
- Inspection Requirements for Altered Equipment: If a platform lift or stairway chairlift undergoes any alterations or modifications, it must be re-inspected and tested to ensure that it still meets the requirements of the ASME A18.1 standard.
By following these inspection and testing requirements, owners and operators of platform lifts and stairway chairlifts can ensure that their equipment remains safe and reliable throughout its lifetime.
Importance of ASME A18.1 for Industry Professionals:
The ASME A18.1 standard plays a critical role in ensuring the safety and reliability of platform lifts and stairway chairlifts. For industry professionals, such as architects, builders, and property owners, understanding and adhering to this standard is essential.
By specifying equipment that complies with ASME A18.1, industry professionals can ensure that their projects meet all applicable building codes and regulations. This not only promotes public safety but also helps to minimize liability and risk.
