equipment currently on the market would be expected to comply without modifications or
adjustments to the dynamic inner roll stop load requirements. It is also believed that commerc la1
lift inner roll stops are sufficiently high to engage or stop the WC footrest and prevent pinchin ;
of the foothoes between the lift platform and the vehicle body.
Hand Rail Dimensions and Strength (S6.4.9 & S7.12) - NHTSA is requiring dual handrails on
lifts designed for Public-use MPVs and buses, but not on lifts designed for personal use vehicles.
The Access Board requires movable hand rails (e.g., hand rails move with the lift) for all lifts I 49
CFR 38.23 (b)(13) on public transportation vehicles. Handrails are necessary for manual
wheelchair passengers to hold onto and assist themselves ordoff the platform, and to control tk eir
speed. They are also used by ambulatory disabled persons (such as those with limited mobilitf
on one side of the body) for assisting themselves ordoff the platform and for standee stability
while raising the lift.
NHTSA is requiring when the Public-use lift is fully deployed, hand rails are available on eacl L
side of the lift in order to accommodate disabled persons who may have mobility limitations c n
either the left or right hand side of their bodies. For lifts designed for personal use vehicles,
handrails are optional, but if available they must meet the same load and deflection requireme its
as described below. The graspable portion of the hand rails are to be located at a height of 7t 2 -
965 mm (30"-38") and are to be a minimum of 203 mm (8") in length. The cross sectional
diameter or width of the handrails are to be between 3 1.5 mm (1.25") and 38 mm (1SO"). Th ,;
handrails are to be capable of withstanding a force of 445 N (100 lbs.) applied with a 1,290 min2
