1、489 Office of the Secretary of Transportation Pt. 38 provide access at those three stops. The sys-tems next ten stops are part of a right-of- way in which level-entry boarding is prac-ticable. In such a case, level-entry boarding would have to be provided at those ten stops. There is nothing inappro

2、priate about the same system having different means of boarding in different locations, in such a case. We also caution against a potential mis-understanding of the sentence in 810.5.3 that provides that Low-level platforms shall be 8 inches minimum (205 mm) above top of rail. This does not mean tha

3、t high- level platforms are prohibited or that low- level platforms are the only design con-sistent with the rules. It simply means that where low-level platforms are otherwise per-mitted, such platforms must be at least 8 inches above the top of rail, except where ve-hicles are boarded from the str

13、ition) 38.1 SOURCE: 56 FR 45756, Sept. 6, 1991, unless otherwise noted. Subpart AGeneral 38.1 Purpose. This part provides minimum guide-lines and requirements for accessibility standards in part 37 of this title for transportation vehicles required to be accessible by the Americans With Dis-abilitie

14、s Act (ADA) of 1990 (42 U.S.C. 1201 et seq.). 38.2 Equivalent facilitation. Departures from particular technical and scoping requirements of these guidelines by use of other designs and technologies are permitted where the alternative designs and technologies used will provide substantially equiva-l

15、ent or greater access to and usability of the vehicle. Departures are to be considered on a case-by-case basis under procedures set forth in 37.7 of this title. 38.3 Definitions. See 37.3 of this title. 38.4 Miscellaneous instructions. (a) Dimensional conventions. Dimen-sions that are not noted as m

16、inimum or maximum are absolute. (b) Dimensional tolerances. All dimen-sions are subject to conventional engi-neering tolerances for material prop-erties and field conditions, including normal anticipated wear not exceeding accepted industry-wide standards and practices. (c) Notes. The text of these

17、guidelines does not contain notes or footnotes. Additional information, explanations, and advisory materials are located in the Appendix. (d) General terminology. (1) Comply with means meet one or more specifica-tion of these guidelines. (2) If or if*then denotes a speci-fication that applies only w

18、hen the conditions described are present. (3) May denotes an option or alter-native. (4) Shall denotes a mandatory speci-fication or requirement. (5) Should denotes an advisory speci-fication or recommendation. Subpart BBuses, Vans and Systems 38.21 General. (a) New, used or remanufactured buses and

19、 vans (except over-the-road buses covered by subpart G of this part), to be considered accessible by regulations in part 37 of this title shall comply with the applicable provisions of this subpart. (b) If portions of the vehicle are modified in a way that affects or could affect accessibility, each

20、 such portion shall comply, to the extent practicable, with the applicable provisions of this subpart. This provision does not re-quire that inaccessible buses be retro-fitted with lifts, ramps or other board-ing devices. 38.23 Mobility aid accessibility. (a) General. All vehicles covered by this su

21、bpart shall provide a level- change mechanism or boarding device (e.g., lift or ramp) complying with paragraph (b) or (c) of this section and sufficient clearances to permit a wheel-chair or other mobility aid user to reach a securement location. At least two securement locations and devices, comply

22、ing with paragraph (d) of this section, shall be provided on vehicles in excess of 22 feet in length; at least one securement location and device, complying with paragraph (d) of this section, shall be provided on vehicles 22 feet in length or less. (b) Vehicle lift(1) Design load. The design load o

23、f the lift shall be at least 600 pounds. Working parts, such as ca-bles, pulleys, and shafts, which can be expected to wear, and upon which the lift depends for support of the load, shall have a safety factor of at least six, based on the ultimate strength of the material. Nonworking parts, such as

24、platform, frame, and attachment hardware which would not be expected to wear, shall have a safety factor of at least three, based on the ultimate strength of the material. (2) Controls(i) Requirements. The controls shall be interlocked with the vehicle brakes, transmission, or door, or shall provide

25、 other appropriate mechanisms or systems, to ensure that the vehicle cannot be moved when the lift is not stowed and so the lift cannot VerDate Mar2010 10:00 Dec 22, 2010 Jkt 220212 PO 00000 Frm 00500 Fmt 8010 Sfmt 8010 Y:SGML220212.XXX 220212jdjones on DSK8KYBLC1PROD with CFRProvided by IHSNot for

26、ResaleNo reproduction or networking permitted without license from IHS-,-,-491 Office of the Secretary of Transportation 38.23 be deployed unless the interlocks or systems are engaged. The lift shall de-ploy to all levels (i.e., ground, curb, and intermediate positions) normally encountered in the o

27、perating environ-ment. Where provided, each control for deploying, lowering, raising, and stow-ing the lift and lowering the roll-off barrier shall be of a momentary con-tact type requiring continuous manual pressure by the operator and shall not allow improper lift sequencing when the lift platform

28、 is occupied. The con-trols shall allow reversal of the lift op-eration sequence, such as raising or lowering a platform that is part way down, without allowing an occupied platform to fold or retract into the stowed position. (ii) Exception. Where the lift is de-signed to deploy with its long dimen

29、-sion parallel to the vehicle axis and which pivots into or out of the vehicle while occupied (i.e., rotary lift), the requirements of this paragraph prohib-iting the lift from being stowed while occupied shall not apply if the stowed position is within the passenger com-partment and the lift is int

30、ended to be stowed while occupied. (3) Emergency operation. The lift shall incorporate an emergency method of deploying, lowering to ground level with a lift occupant, and raising and stowing the empty lift if the power to the lift fails. No emergency method, manual or otherwise, shall be capable of

31、 being operated in a manner that could be hazardous to the lift occupant or to the operator when operated ac-cording to manufacturers instructions, and shall not permit the platform to be stowed or folded when occupied, unless the lift is a rotary lift and is intended to be stowed while occupied. (4

32、) Power or equipment failure. Plat-forms stowed in a vertical position, and deployed platforms when occupied, shall have provisions to prevent their deploying, falling, or folding any faster than 12 inches/second or their dropping of an occupant in the event of a single failure of any load carrying

33、compo-nent. (5) Platform barriers. The lift platform shall be equipped with barriers to pre-vent any of the wheels of a wheelchair or mobility aid from rolling off the platform during its operation. A mov-able barrier or inherent design feature shall prevent a wheelchair or mobility aid from rolling

34、 off the edge closest to the vehicle until the platform is in its fully raised position. Each side of the lift platform which extends beyond the vehicle in its raised position shall have a barrier a minimum 112 inches high. Such barriers shall not interfere with maneuvering into or out of the aisle.

35、 The loading-edge barrier (outer bar-rier) which functions as a loading ramp when the lift is at ground level, shall be sufficient when raised or closed, or a supplementary system shall be pro-vided, to prevent a power wheelchair or mobility aid from riding over or defeat-ing it. The outer barrier o

36、f the lift shall automatically raise or close, or a supplementary system shall automati-cally engage, and remain raised, closed, or engaged at all times that the platform is more than 3 inches above the roadway or sidewalk and the plat-form is occupied. Alternatively, a bar-rier or system may be rai

37、sed, lowered, opened, closed, engaged, or disengaged by the lift operator, provided an inter-lock or inherent design feature pre-vents the lift from rising unless the barrier is raised or closed or the sup-plementary system is engaged. (6) Platform surface. The platform sur-face shall be free of any

38、 protrusions over14 inch high and shall be slip re-sistant. The platform shall have a min-imum clear width of 2812 inches at the platform, a minimum clear width of 30 inches measured from 2 inches above the platform surface to 30 inches above the platform, and a minimum clear length of 48 inches mea

39、sured from 2 inches above the surface of the plat-form to 30 inches above the surface of the platform. (See Fig. 1) (7) Platform gaps. Any openings be-tween the platform surface and the raised barriers shall not exceed 58 inch in width. When the platform is at vehi-cle floor height with the inner ba

40、rrier (if applicable) down or retracted, gaps between the forward lift platform edge and the vehicle floor shall not exceed 12 inch horizontally and 58 inch vertically. Platforms on semi-auto-matic lifts may have a hand hold not exceeding 112 inches by 412 inches lo-cated between the edge barriers.

42、ance ramp. The en-trance ramp, or loading-edge barrier used as a ramp, shall not exceed a slope of 1:8, measured on level ground, for a maximum rise of 3 inches, and the transition from roadway or sidewalk to ramp may be vertical without edge treatment up to 14 inch. Thresholds be-tween 14 inch and

43、12 inch high shall be beveled with a slope no greater than 1:2. (9) Platform deflection. The lift plat-form (not including the entrance ramp) shall not deflect more than 3 degrees (exclusive of vehicle roll or pitch) in any direction between its unloaded po-sition and its position when loaded with 6

44、00 pounds applied through a 26 inch by 26 inch test pallet at the cen-troid of the platform. (10) Platform movement. No part of the platform shall move at a rate exceed-ing 6 inches/second during lowering and lifting an occupant, and shall not ex-ceed 12 inches/second during deploying or stowing. Th

45、is requirement does not apply to the deployment or stowage cy-cles of lifts that are manually deployed or stowed. The maximum platform hor-izontal and vertical acceleration when occupied shall be 0.3g. (11) Boarding direction. The lift shall permit both inboard and outboard fac-ing of wheelchair and

46、 mobility aid users. (12) Use by standees. Lifts shall ac-commodate persons using walkers, crutches, canes or braces or who other-wise have difficulty using steps. The platform may be marked to indicate a preferred standing position. (13) Handrails. Platforms on lifts shall be equipped with handrail

47、s on two sides, which move in tandem with the lift, and which shall be graspable and provide support to standees throughout the entire lift operation. Handrails shall have a usable component at least 8 inches long with the lowest portion a minimum 30 inches above the platform and the highest portion

48、 a maximum 38 inches above the platform. The hand-rails shall be capable of withstanding a force of 100 pounds concentrated at any point on the handrail without perma-nent deformation of the rail or its sup-porting structure. The handrail shall have a cross-sectional diameter be-tween 114 inches and

49、 112 inches or shall provide an equivalent grasping surface, and have eased edges with corner radii of not less than 18 inch. Handrails shall be placed to provide a minimum 112 inches knuckle clearance from the nearest adjacent surface. Handrails shall not interfere with wheelchair or mobility aid maneuverability when en-tering or leaving the vehicle. (c) Vehicle ramp(1) Design load. Ramps 30 inches or longer shall support a load o
