Minimum ratio: actual

rear axle/ mass of the
unladen tractor
Legal
requirement
Required front ballast
To calculate
FWr
Ballast required at the front when
carrying a load RW at the rear
CALCULATION OF FWr
M*e = R1*b
e = (R1*b)/M
RW*(c+d) - (M *e) + (RF *b) = FWr*(a+b)
RF > 0.2*M
RF value must be higher than 0.2*M
FWr>[RW*(c+d- (R1*b)+(0.2*M*b)]/(a+b)
Required rear ballast
To calculate
RWr
Ballast required at the rear when
carrying a load FW at the front
CALCULATION OF RWr
M*b (b- e) = R2*b
FW*a - M *(b- e)+ (RR*b) = RWr*(b+c+d)
RW*(c+d) - (M *e) + (RF *b) = FWr*(a+b)
RR > 0.45*M
RR value must be higher than 0.45*M
RWr> [(FW*a) - (R2 *b)+(0.45 *M*b)]/(b+c+d)
Axle load limits
To calculate:
RF
RF < RFmax
RR
RR < RRmax
W
W < Wmax
CALCULATION OF RF
(RF*B) - FW*(A + B) - (M*E)+ RW*(C + D)
RF = [FW *(A+B)+ (R1*B) - RW*(C+D)]/B
< RFmax
CALCULATION OF W
W = FW + M + RW < Wmax
CALCULATION OF RR
R2T = W - RF < RRmax
