ELATECH® belts do not need any safety factor. However if there
are unknown peaks or shock loads or swings in the peripheral
force unknown at design time, which therefore can not be inclu-
ded in the calculation parameters, a suitable safety factor should
be considered by the designer.
Steady load c 1 = 1
Peak or fluctuating loads:
Light c 1 = 1,4
Medium c 1 = 1,7
Heavy c 1 = 2,0
