Stability considerations
The stability of a vehicle with a loading crane is determined by several factors, such
as the type and weight of the load to be moved, or the surface on which the vehicle
is standing.
Attention must be paid to the asymmetric installation of the crane. The maximum
load difference between the wheels on the same axle (unilateral axle load) must not
be exceeded.
Stability must be ensured by support feet, which are laterally extended. The use of
hydraulic feet is recommended. The support feet protruding beyond the vehicle
must be properly marked with reflective paint, reflectors, or any other signalling
method approved.
The crane must be used on flat and stable surfaces.
During operation of the crane, the extendable support feet must be always extend-
ed and in contact with the ground, as this ensures the best possible stability.
The turning radius of the crane should be limited. A critical situation with respect to
stability occurs when the crane is placed obliquely in front of the vehicle, above the
cab. In this position, the lifting capacity of the crane and its turning radius will be
seriously limited. It is recommended to ensure that the range of motion of the crane
work is limited to the area behind the supporting legs.
