7. Product technical features

RECOMMENDATIONS:
All technical features stated make reference at a room
temperature of 20°C (± 5°C).
King Gates reserves the right to modify the product at any
time it deems necessary, however maintaining the same
functionality and destination of use.

8. Product duration

The duration and average economic life of the product. The
value of duration is strongly affected by the fatigue index of the
manoeuvres performed by the automation: i.e. the sum of all
factors that contribute to wear of the product (see Table 1).
The estimation of duration is made on the basis of the design
calculations and the test results performed on prototypes. In fact,
as it is an estimate, it does not represent any guarantee regarding
the effective duration of the product.
To establish the probable duration of your automation, proceed
as follows:
01. Calculate the fatigue index by adding the percentage values of
the items present in Table 1.
02. In Graph A of the value just found, trace a vertical line that
crosses the curve; from this point trace a horizontal line until
the "manoeuvre cycles" line is crossed. The value determined
is the estimated duration of your product.
Example of the duration calculation of an gear motor.
Refer to Table 1 and Graph A:
1) - Panel length: 1.7 m
2) - Panel weight: 200 kg = fatigue index: 20%.
3) - Installation in windy areas = fatigue index: 15%.
4) - Does not have other elements of fatigue.
Total fatigue index = 35%
Estimated duration = 120.000 manoeuvre cycles
