
Stability
Do not carry unstable or loose loads, or loads which are oversized with respect to the
dumper
(fig. 1) .
When the bucket is being lifted, ensure that the dumper is on stable ground and that it
is as flat as possible.
Do not drive over objects which may endanger the stability of the machine.

The triangle of horizontal stability
To prevent the loads which are being transported from falling, it is necessary to consider
the triangle of horizontal stability
(fig. 2) . This is an imaginary inverted triangle, with the
lower end located on the centre of the rear axle and the two upper vertices on each of
the front wheels. Stability is guaranteed when the centre of gravity of load
(C) and the
machine (M) always remain within an imaginary line, starting from the lower vertex of the
triangle to the centre of the base of the same, located between the front wheels.

Longitudinal stabilization
The dumper must not be driven with the bucket raised. The risk of longitudinal overturning
increases if the dumper is driven while the load is raised. Sharp braking and accelerating
or rapid tilting movements decrease stability.

Transversal stability
The risk of overturning sideways increases on turning at unsuitable speeds, while
the dumper is unladen or when the load is raised. Rough ground, sharp braking or
accelerating or shifts in the load make these conditions worse.

The centre of gravity and the dumper capacity
Do not overload the dumper or handle loads which shift the centre of gravity beyond
that for which it is designed. Manoeuvre slowly, especially when changing direction on
slippery ground.

The load and counterweight
The raised load should only be tilted forwards when it is about to be unloaded.
Tilting the load forwards or backwards (swinging) is very useful for collecting or
positioning the load, but affects the longitudinal and lateral stability.
If using an accessory or attachment first check the permitted load. The combination of
the weight of the dumper plus the weight of the accessory reduces the nominal load.

Maximum speed
The speed of the dumper influences its stability. When turning, braking, or accelerating,
the centre of gravity shifts within the triangle of stability. Sharp turns, sudden braking or
accelerating cause the centre of gravity to shift sharply and it may fall outside the triangle.
This is the moment when the stability of the dumper and the load are not guaranteed and
there is a risk of accident.
When manoeuvring reduce the speed of the dumper and avoid turning the steering
wheel sharply.
 The surrounding area
Give your full attention to the task in hand. The safety of the driver and others depends
upon the care taken by the driver
(fig. 3) .
