Tabel No. 3. Calculations of required ballasts
REQUIRED BALLAST IN FRONT
REQUIRED BALLAST ON THE REAR
BRr
–
ballast required on the front during transport
of BF load on the rear
BRr
–
ballast required in the rear during transport
of BF load in the front
MT · e = MF · b
e = (MF · b)/MT
MT · (b –
e) = MR · b
BR · (c + d)

e) + (MPR · b) = BRr · (b + c + d)
MPF > 0,2 · MT
Maximum permissible weight of front axle must be greater
than 0.2 × vehicle curb weight without load
MPR > 0.45 · MT
Maximum permissible weight of the rear axle must be greater
than 0.45 × vehicle curb weight without load
BFr > [BR·(c+d)
-
(MF·b) + (0,2·MT·b)] / (a+b)
BRr > [(BF·a)
-
(MR·b) + (0,45·MT·b)] / (b +c +d)
You should read the Instruction Manual of the vehicle (tractor), get to know
maximum axle load and fulfil the below conditions, so as to achieve:
MPF < MPF
max
of the tractor
MPR < MPR

MPT < MPT
