4.2 PRELIMINARY CHECKS: gate structure; guides; rails and sliding wheels
Effective installation requires that the gate and its mechanical features comply with the construction and functional
characteristics of safety and sliding performance.
For this purpose it is necessary to carry out the inspections indicated below and all apposite interventions.

Inspection of the gate structure
The gate structure must be:
• rigid, straight and in good condition, without poorly fi xed
or partially detached parts
• without automatic locking devices (remove any automatic
locking devices)
Inspection of lower rail
The lower rail of the opening wing must be:
• straight, horizontal (use a spirit level) and in good
condition
• equipped with a LIMIT STOP of the opening wing
(Fig.6)
to prevent the gate from slipping out of the rail and
consequently A SERIOUS RISK OF OVERTURNING.
Choosing the wheels
The wheels must be:
• suitable for the type of rail profi le used: with round or
“V” section
(Fig.7)
• with a diameter at least 120 mm and dimensions suitable
for the lower rail profi le
• in good condition and suitable for the gate weight
• MAX TWO; positioned in the vicinity of the gate ends
If these requirements are not fully met, wheels HAVE
TO BE REPLACED.
Checking the upper guides
The upper guides must be:
• at least 2, fl ush with the gate panel
• they must prevent the gate from oscillating during
operation
• they shall produce no friction during motion.
Some installation examples are shown in
Fig.8
.
Warning
!
• The gate structure must comply with current SAFETY
rules, especially at points where there is a danger of
CRUSHING or SHEARING.
• The gate MUST BE EASILY MOVED BY HAND so
that it can be opened in the event of manual release.
