ASME A18.1:2017 pdf free download – Safety Standard for Platform Lifts and Stairway Chairlifts
1.1.1 Equipment Covered by This Standard. This safety Standard covers the design, construction, installa- tion, operation, inspection, testing, maintenance, and repair of inclined stairway chairlifts and inclined and vertical platform lifts intended for transportation of a mobility impaired person only. The device shall have a limited vertical travel, operating speed, and platform area. Operation shall be under continuous control of the user/attendant. The device shall not penetrate more than one floor. A full passenger enclosure on the plat- form shall be prohibited.
The provisions of this Standard are not intended to preventthe use ofsystems, methods, or devices ofequiv- alent or superior quality, strength, fire resistance, effec- tiveness, durability, and safety to those prescribed by this Standard, provided that there is technical documen- tation to demonstrate the equivalency of the system, method, or device. The specific requirements of this Standard shall be permitted to be modified by the authority having juris- diction based upon technical documentation or physical performance verification to allow alternative arrange- ments that will assure safety equivalent to that which would be provided by conformance to the correspond- ing requirements of this Standard.
alteration: any change to equipment other than mainte- nance, repair, or replacement. approved: acceptable to the authority having jurisdiction. authority having jurisdiction: organization, office, or indi- vidual responsible for approving equipment. Where compliance with this Standard has been mandated by law, the “authority having jurisdiction” is the federal, state, or local department or individual so designated in the enacting legislation or administrative regulation. authorized personnel: persons who have been instructed in the operation of the equipment and designated by the owner to manage the use of the equipment. building code: an ordinance that sets forth requirements for building design and construction, or where such an ordinance has not been enacted, the International Code Council (ICC), International Building Code (IBC), and International Residential Code (IRC) are the code standards.
governor pull-retarding means: a mechanical means of developing a sufficient force in the governor rope to activate the platform or counterweight safeties or to trip the governor rope releasing carrier, where used. Such mechanical means include, but are not limited to, rope-gripping jaws, clutch mechanisms, and traction arrangements. governor pull-through tension (force): the magnitude of the tensile load developed in the moving governor rope after the governor rope-retarding means is actuated. inclined platform lift: a powered hoisting and lowering mechanism designed to transport mobility-impaired persons on a guided platform that travels on an incline. inclined stairway chairlift: a powered hoisting and low- ering mechanism that is guided, equipped with a seat, to transport seated passengers along stairways.
installation, new: any installation not classified as an existing installation by definition, or an existing plat- form lift or stairway chairlift moved to a new location subsequent to the effective date of this Standard. installation, placed out ofservice: an installation whose power feed lines have been disconnected from the machine disconnect switch. labeled: equipment or materials to which has been attached a label, symbol, or other identifying mark of an independent certifying organization concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a speci- fied manner.
