CONTROLS TO STABILIZE THE VEHICLE
The outriggers rams prevent hurmful stresses both to the frame and to the
vehicle suspensions on which the crane is mounted and assure the stability
of the unit during load handling.
Supplementary beams (optional)
Supplementary beams (supplementary outriggers) are used in conjunction
with the crane outriggers to ensure the vehicle stability during load handling.
They are hydraulically extendable.
Supplementary outrigger ram extension max.
beam code stroke interaxis
190B070 340 mm 4142 mm hydraulic extension
190B072 550 mm 4142 mm hydraulic extension
Identification data of the supplementary beam are punched on the beam (fig. 12)
in the following sequence:
Example *190B070*0001*
serial no.
identification code
! ATTENTION !
(!) The crane stability is only guaranteed by the maximum lateral
extension of the outrigger supports of the crane and supplementary
outriggers
Be very careful during vehicle stabilization operation; make sure that no one
is or transits in close proximity of the working area of the outriggers.
Check that they are applied on a solid base; the maximum plate pressure of
the rams is:
25,1 daN/cm
2
on a plate which diameter is 230 mm
If needed use the special base plates (on request).
When stabilization is complete the wheels of the vehicle must still be in
contact with the ground and the suspensions must not be fully
unloaded.
Level the crane so as to operate on a horizontal plane.
The crane is supplied with outrigger supports having hydraulic side
extension. (On request hydraulic extra extendable supports).
The controls to stabilize the vehicle are activated only on ground level and on
both sides of the crane base.
