Symbol Description

add

Moment of inertia of the cable drum, the deflection and guiding rollers, etc.

• The moment of inertia of the hoisting cage does not have to be taken into consideration here

since it is already included.

• The moment of inertia has an effect on the dynamic torque!

• Value can be entered directly or calculated using the inertial calculator.

Width of the cable drum

• Is used to determine the number of layers of the cable on the drum, and thus the increase in

the effective drum diameter.
