Step 2:

Check whether the distances between the applied forces are within the permissible values (see maximum permissible distances).

Variant:1 rail1 trolley
sy + sz<2 Lx - Y0
ay + az<2 Lx - Y0
sy< 5 Zm
sz<5 Zm

Calculating the required drive force

3.1

Step 3.1

Centre of mass in x- and z-direction within the carriage(s)

3.2

Step 3.2

Centre of gravity in z-direction outside the carriage(s)

3.3

Step 3.3 01

Centre of gravity in x-direction outside the carriage(s)

Step 3.3

If the position of the centre of mass cannot be classified:

Variables in the calculations

Fa:drive force[N]
Fs:Mass force[N]
