B4. Car and counterweight
B4.1. Car dimensions
B4.1.l. The dimensions and the arrangement of the car should
manifestly prevent the access of persons. Accordingly the hori-
zontal dimensions of the car (width and depth) should not exceed
3ft 4in. (im) and its height should not exceed 4ft (l.20m).
Exceplion
However, a height of more than 4ft is permissible ifthe car has
several fixed compartments meeting the above-mentioned require-
ments.
B4.2. Car walls, floor and roof
B4.2.l. The car should be completely closed, except for the
door openings, by walls, a floor and a roof.
134.2.2. The car walls, the floor, the roof and any shelving
in the compartments dividing the car:
should be sufficiently strong (see B4.2.3); and
should, in case of fire, keep their strength as long as required,
and should not consist of materials apt to become dangerous
owing to their high flammability or as a result of the nature and
quantity of the fumes which they would produce in the event
of a fire.
B4.2.3. The car walls, the floor, the roof and any shelving in
the compartments dividing the car should be sufficiently strong to
withstand the stresses to which the car is subjected during normal
operation of the lift (taking into account the nature of the load
carried) when it strikes the buffers (or other arresting devices) or
when the safety gear operates if the car is fitted with such gear.
