Belt weight
If the mass per metre of the belt is not given, you have the possibility to determine it yourself. To do
this, weigh the belt and divide the weight in kilogrammes by the total length of the belt in metres.

Trum force
With the specified mass per belt metre, the trum length and the measured frequency in Hertz, the
trum force can now be determined. It is calculated on the basis of the following formula:
𝐹
𝑡𝑟𝑢𝑚
= 4 ∗ 𝑚
𝑚𝑒𝑡𝑒𝑟

f
= Frequency in Hertz
The determined trum force can be compared with the specifications of the drive manufacturers and
the belt tension can then be adjusted according to the set point.
