Types of Risks
1
Structural and wear-and-
tear mechanical risks
[1] Loss of stability
1.3.1
1.3.2
and parts falling off
1.5.15
[2] Slipping
1.3.7
Mechanical risks caused by the movement of the door (see references in figure 1)
1.3.8
□
WARNING - If the door/gate is used exclusively with the man-operated controls (and complies with the
1.4
requirements of regulation EN 12453) it is not necessary to protect the hazard points listed below.
□
WARNING - If the safety devices are installed (in accordance with regulation EN 23978) which prohibit
all contact between the moving door and people (e.g. photo-electric barriers, detectors), it is not
necessary to measure the actual operative stress.

Evaluation Criteria and Solutions to Adopt
(Check the box corresponding to the solution adopted)
□
Check the stability of this structure (columns, hinges, doors) compared with
the motor-generated stress.
Firmly fasten the motor using the proper materials.
□
If necessary, perform structural calculations in the appendix of the Technical
Documentation.
□
Check that the thrust of the doors is limited (when opening and closing) by
appropriately firm mechanical stops.
□
Check that eventual thresholds greater than 5 mm are visible, marked and
modeled.
