ParaLift Lock Brackets
With the spray boom folded in transport position, the ParaLift is in locked position. This is to prevent accidental movements
of the boom while driving on the road.
Description of the Lock Mechanism
When the boom is fully folded and the hydraulic cylinder (A) for the
ParaLift fully extends to raise the boom into transport position, a lock
bracket (B) automatically lowers onto the extended piston rod by means
of another hydraulic cylinder (C).
The lock bracket will now prevent the piston rod from retracting
unintentionally during road transport, if the hydraulic pressure drops.
The lock bracket helps to ensure a safe transport position of the boom.
±
WARNING! During road transport, it is important that the lock
bracket (B) be in the lock position. If not, it could cause a
dangerous situation, if the hydraulic pressure drops. Risk of the
boom gliding out of the transport brackets, resulting in damage
to the wheel mudguards and further damage to the sprayer. The
extent of the damage depends on the sprayer and boom size.
However, this damage is depending on other components failing as well.
Service Situation
€
DANGER! In a service situation, it is very important that the lock
bracket (B) be in the lock position. If the hydraulic pressure drops
when standing below the ParaLift, it could cause a dangerous
situation from a quickly lowered ParaLift.
Risk of squeezing and being trapped. Risk of fatal accidents.
