S = 75 kg
Max permissible load of towing trailer
R = 1200 kg
D - force is calculated using the following formula:
T-technically permissible maximum mass in tonnes of the towing vehicle (also towing
tractors) including, if neccessary, the vertical load of a centrale axle trailer.
TxR
D
= g kN R-technically permissible maximum mass in tonnes of the full trailer with drawgal free
