Risk of accident if outrigger beams cannot be seen
Cordon off the area where you intend to extend and retract the outrigger
beams. Nobody is allowed to be in this area.
Observe the moving outrigger beams or have them observed by a banks-
man who is in visual contact with you.
G
Danger of overturning if improperly supported
Always extend all the outrigger beams, and always extend them to the
spans corresponding to the RCL code.
This also applies if you are working on one side only, since it ensures that
the truck crane is stable at the rear.
S
Risk of damage to the outriggers
Before extending, always check whether the required pins for the desired
outrigger span are inserted/removed.
Before retracting the outrigger beams, always check whether they have
been secured in driving position.
