Paralift Lock Brackets
With the spray boom folded in transport position, the paralift is locked in position. This is to prevent accidental movements
of the boom while driving on the road.
Description of the Lock Mechanism
The hydraulic cylinder (A) for the paralift extends fully to raise the boom
into transport position.
A lock bracket (B) will then automatically be lowered onto the extended
piston rod by means of another hydraulic cylinder (C), when the boom
is fully folded.
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 is 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
mudguards for the wheels and further damage to the sprayer.
The extent of the damage depends on the sprayer size 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) is in the lock position. If the hydraulic pressure drops,
when you are standing below the paralift, it could cause a
dangerous situation, as the paralift will be lowered quickly.
Risk of squeezing and getting trapped. Risk of fatal accidents.
