Boom
Boom configurations
The DELTA FORCE boom is trapeze suspended and fully hydraulically operated with all functions controlled via the Direct
Hydraulic System (D.H.).
The DELTA FORCE boom is suspended from a trapeze with nitrogen dampers and is available in 88’, 90’, 100’, 120’and132’
(26.8, 27.4, 30.5, 36.6, 40.2 m) working widths. The 88’- 100’booms have bi-fold wings, while the 120’ - 132’ booms have tri-
fold wings.
Boom features:
•Outer most sections incorporate spring-loaded breakaway.
•Individual boom tilt control.
•Partial folding of outer sections. This enables alternative boom widths.

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.

Hydraulics
Hydraulic Block
Spray Boom
The main hydraulic block manages hydraulic pressure for the boom
controls.
Yaw D amp ing
The unfolded spray boom will create yaw movements when:
•driving over uneven terrain
•turning on headland
•speeding up
•braking.
There are 2 types of damping:
•Mechanical
•Hydraulic
Damping Function (Mechanical Yaw)
Rubber blocks located on the hinge assembly provide damping when
the boom makes a yaw movement.
Damping Function (Hydraulic Yaw)
The three accumulators located in the boom center act as dampers for
the yaw movements, when driving in the field. Each accumulator contains nitrogen gas and hydraulic oil, separated by a
diaphragm. When the boom makes a yaw movement, hydraulic oil will be transferred into the accumulator. The oil pushes
the diaphragm while compressing the gas. When this compression overcomes the oil pressure from the boom, the boom
wing is moved back to its original position dampened by the oil flow in the circuit.

Hydraulic systems
General info
Ensure that the quick couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check the vehicle’s hydraulic oil level and top off, if
necessary.
€
DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which
can cause violent movements of the boom.
€
DANGER! Hydraulic leaks: Never use your fingers to locate a leakage in any part of the hydraulic system. Due to high
pressure, hydraulic oil may penetrate the skin.
Requirements - tractor (DELTA FORCE model)
The hydraulic system requires:
•One double-acting outlet for the electro-hydraulic operation of the boom functions. The hydraulic hoses are marked
with arrows and colored tie straps to indicate direction of oil flow. Red tie strap = pressure. Green tie strap = Return to
tank. The hoses must be hooked up to the correct outlet for the hydraulics to function properly (pressure hose to
pressure outlet, return hose to tank outlet).
•Oil flow between 4 - 21 gal/min. (15 - 80 l/min) and a min. pressure of 2610 psi (180 bar).
•Maximum permissible oil pressure is 3050 psi (210 bar).
•Return flow of the connected tractor must be maximum 215 psi (15 bar).
•For Load Sensing systems an oil flow of approximately 0.8 gal/min (3 l/min) at 360 psi (25 bar) is supplied by the sprayer
hydraulics.
