1.1.1 Equipment Covered by This Code This Code covers the design, construction, operation, inspection, testing, maintenance, alteration, and repair of the following equipment, its associated parts, and its hoistways, where located in or adjacent to a building or structure (except as modified by 1.2): (a) hoisting and lowering mechanisms, equipped witha carorplatform, whichmove betweentwo or more landings. This equipment includes, but is not limited to elevators (see 1.3). (b) power-driven stairways and walkways for car- rying persons between landings. This equipment includes, but is not limited to escalators and moving walks (see 1.3). (c) hoisting and lowering mechanisms equipped with a car that serves two or more landings and is restricted to the carrying of material by its limited size or limited access to the car. This equipment includes, but is not limited to dumbwaiters and material lifts (see 1.3). 1.1.2 Equipment Not Covered by This Code Equipment not covered by this Code includes, but is not limited to, the following: (a) personnel hoists within the scope of ANSI A10.4 and CSA-Z185 (b) material hoists within the scope of ANSI A10.5 and CSA-Z256 (c) platform lifts and stairway chairlifts within the scope of ASME A18.1, CSA B355, and CSA B613 (d) manlifts within the scope of ASME A90.1 and CSA B311 (e) mobile scaffolds and towers; platforms within the scope of ANSI/SIA A92 and CSA-B354 (f) powered platform and equipment for exterior and interior building maintenance within the scope ofASME A120.1 and CSA-Z271 (g) conveyors and related equipmentwithinthe scope of ASME B20.1 1 (h) cranes, derricks, hoists, hooks, jacks, and slings within the scope of ASME B30, CSA Z150, CSA B167, CSA Z202, and CSA Z248 (i) industrial trucks within the scope of ASME B56 and CSA B335 (j) portable equipment, except for portable escalators, which are covered by 6.1 (k) tiering or piling machines used to move material to and from storage located and operating entirely within one story (l) equipment for feeding or positioning material at machine tools, printing presses, etc. (m) skip or furnace hoists (n) wharf ramps (o) amusement devices (p) stage and orchestra lifts (q) lift bridges (r) railroad car lifts and dumpers (s) mechanized parking garage equipment (t) line jacks, false cars, shafters, moving platforms, and similar equipment used for installing an elevator (u) platform elevators installed in a ship or offshore drilling rig and used for the purpose of loading and unloading cargo, equipment, and personnel (v) docklevelers (freightplatformlifts) havingatravel of 500 mm (20 in.) or less (w) in Canadian jurisdictions, devices having a travel of2 000 mm (79 in.) or less and used only for the transfer of materials or equipment 1.1.3 Application of Parts This Code applies to new installations only, except Part 1, and 5.10, 8.1, 8.6, 8.7, 8.8, 8.9, 8.10, and 8.11, which apply to both new and existing installations. 1.1.4 Effective Date The requirements of this edition and subsequent addenda to the Code are effective as of the date noted on the copyright page of this document. The authority having jurisdiction will establish the effective date for their local regulations.
braking system: driving-machine brake alone, or in combination with electrically assisted braking, which operates to slow down and stop the elevator. See Non- mandatory Appendix F. buffer: a device designed to stop a descending car or counterweight beyond its normal limit of travel by stor- ing or by absorbing and dissipating the kinetic energy of the car or counterweight. oilbuffer: abufferusingoilas amedium, whichabsorbs and dissipates the kinetic energy of the descending car of counterweight. gas spring-return oil buffer: an oil buffer utilizing the pressureofacompressedgas to returnthe bufferplunger or piston to its fully extended position. mechanical spring-return oil buffer: an oil buffer utiliz- ing the force of the compressed mechanical spring or springs to return the buffer plunger or piston to its fully extended position. oil buffer stroke: the oil-displacing movement of the buffer plunger or piston, excluding the travel of the buffer plunger accelerating device. spring buffer: a buffer utilizing one or more springs to cushion the impact force of the descending car or counterweight. spring buffer load rating: the load required to com- press the spring buffer an amount equal to its stroke. spring buffer stroke: the distance the contact end of the spring can move under a compressive load until all coils are essentially in contact or until a fixed stop is reached. 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) International Building Code (IBC) (b) Building Construction and Safety Code (NFPA 5000) (c) National Building Code of Canada (NBCC) NOTE: Local regulations or laws take precedence. In the absence of local regulation a model building code is applicable. bumper: a device, other than an oil or spring buffer, designed to stop a descending car or counterweight beyond its normal limit of travel by absorbing the impact. cable, traveling: see traveling cable. capacity: see rated load. car door interlock: a device having two related and interdependent functions, which are: (a) to prevent the operation of the driving machine by the normal operating device unless the car door is locked in the closed position 3 (b) to prevent the opening of the car door from inside the car unless the car is within the landing zone and is either stopped or being stopped car door or gate, power-closed: a door or gate that is closed by a door or gate power operator. car door or gate electric contact: an electrical device, the function of which is to prevent operation of the driving machine by the normal operating device unless the car door or gate is in the closed position.
