ASME A18.1-2005 pdf download.Safety Standard for Platform Lifts and Stairway Chairlifts.
1 INTRODUCTION 1.1 Scope 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. 1.1.2 Equipment Not Covered by This Standard. Equipment not covered by this Standard includes, but is not limited to, the following: (a) elevators, escalators, moving walkways, material lifts, and dumbwaiters within the scope of ASME A17.1b–1997 and later edition (b) personnel hoists within the scope of ANSI A10.4 (c) manlifts within the scope of ASME A90.1 (d) powered platform and equipment for exterior and interior building maintenance within the scope of ANSI A120.1 (e) portable equipment (f) amusement devices (g) stage and orchestra lifts 1.1.3 Application. This Standard applies to new installations only. 1.1.4 Effective Date. The requirements of this edition to the Standard are effective as ofthe date established by the local regulations ofthe authority having jurisdiction. Where the Standard has not been adopted by local regu- lation and a specific edition has not been stipulated by contractual agreement, compliance with this edition is recommended as of the effective date listed in the front of the document.
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. 1.3 Definitions This section defines various terms used in 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 and/or maintenance of the equipment and designated by the owner to use or maintain the equipment. building code: an ordinance that sets forth requirements for building design and construction, or where such an ordinance has not been enacted, one of the following model codes: (a) National Building Code (b) Standard Building Code (c) Uniform Building Code cable, traveling: see traveling cable. capacity: see rated load. certified: a certification by a testing laboratory, a profes- sional engineer, a manufacturer, or a contractor that a device or an assembly conforms to the requirements of this Standard.
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. 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 arrange- ments. 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. inspection and tests acceptance: the initial inspection and tests of new or altered equipment to check for compliance with the applicable requirements. periodic: routine inspection and tests plus additional detailed examination and operation of equipment at specified intervals witnessed by an inspector to check for compliance with the applicable requirements.
