A
Right angle distance from the loader swing centre to the tipping edge
B
Right angle distance from the end of the boom (from the loader) to the tipping edge
C
Right angle to the distance from the vehicle rear axle centre to the tipping edge
E
Right angle distance from the loader boom centre of gravity to the tipping edge
G
Maximum load at the distance A+B
N
Loader weight without the booms
P
The weight of the booms

Required extra weight to the centre of the rear axle
Line X -X is a tipping edge, it runs through the centre of the front axle and through the centre of the rear
wheel.
Note! If the stability coefficient n becomes smaller than 1.0 in the calculation, extra weights must be used to
get enough stability. Extra weight can be determined by calculation the value for M
