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 trifold wings.

Boom features:

• Outer most sections incorporate spring-loaded breakaway.

• Individual boom tilt control.

• Partial folding of outer sections. This enables alternative boom widths.

3 - Description

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.

3 - Description

Yaw D am pin g

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.

Safety info

The boom must not be folded/unfolded while driving! Never use the folding/unfolding functions before the sprayer has been stopped! Failure to do so will damage the boom.

DANGER! Before unfolding the boom it is important to connect trailed sprayers to the tractor to prevent overturning

€

the sprayer.

DANGER! When folding or unfolding the boom, make sure that no persons or objects are within the operating area

€

of the boom.

DANGER! Always follow the guidelines listed below when driving in areas with overhead power lines:

Lubrication

General info

Always store lubricants clean, dry and cool - preferably at a constant temperature - to avoid contamination from dirt and condensed water. Keep oil filling jugs, hoppers and grease guns clean, and clean the lubricating points thoroughly before lubricating. Avoid prolonged skin contact with oil products.

Always follow the quality and quantity recommendations. If no quantity is recommended, lubricate until new grease becomes visible.

Pictograms in lubrication & oiling plans indicate the following:

1. Lubricant to be used (see “Recommended lubricants” below).

2. Recommended intervals. Shown in hours or with a symbol for

occasional maintenance.

3. Amount to be used. Only shown if an amount is specified.

ATTENTION! If the sprayer is cleaned with a high pressure cleaner,



lubrication of the entire machine is recommended.

Recommended lubricants

BALL BEARINGS: Universal Lithium grease, NLGI No. 2 CHEVRON Multifak EP 2

SHELL RETINAX EP2 CASTROL LMX GREASE

SLIDE BEARINGS: Lithium grease with

CASTROL MOLYMAX

OIL LUB. POINTS: TOTAL Transmission TMSAE 80W/90

Castrol EPX 80W/90 SHELL Spirax 80W/90 Mobil Mobilube 80W/90

Grease Nipple

When lubricating the sprayer, please use a grease gun which fits the dimensions of the grease nipple.

Nipple head type: DIN 71412 Nipple head size (A): 6.5 mm

ATTENTION! If grease is leaking from the nipple near its threaded



part when grease is being applied, please tighten the nipple by using a wrench or socket. Replace the nipple if it is damaged or bent out of shape.

ATTENTION! If applying grease into the nipple seems difficult,



unscrew the nipple. Check if the nipple is blocked inside, or if the spring-loaded ball is stuck. Clean or replace as needed.

6 - Maintenance

Grease Gun Calibration

Before lubricating the sprayer, you must calibrate your grease gun to ensure that the correct amount of grease is applied to each lubrication point. The correct amount of grease applied will prolong the lifetime of the sprayer.

Calibration Example

1. Insert the correct grease cartridge in your grease gun.

2. Apply grease onto a tissue or a piece of paper. Complete 10 full

strokes of the grease gun.

3. Place the paper with grease on a scale (A).

4. If your grease pile weighs for example 10 grams, then 1 stroke

equals 1 gram of grease.

When calibrated, you can count how many strokes to complete, when lubricating the different grease points on the sprayer according to the specifications.

Alternative Method

1. Count the strokes, until you have 10 grams of grease piled up on the scale (A).

2. Now you can figure out how many strokes to use for applying a certain amount of grease to a lubrication point.

DANGER! Adjustment of hydraulic cylinders is to be carried out without pressure in the system.

ATTENTION! For information on boom terminology, see “Boom configurations” on page 11.



ATTENTION! To check the boom alignment, you can use a spirit level, or you can measure the distance to the ground



from similar points in both ends of the boom wing (this method is used for horizontal alignment and only on level ground). When using the latter method, both distances should be equal to obtain a horizontal boom.

ATTENTION! Boom sections, which are not supported during adjustment jobs, might fall down or be difficult to adjust.



ATTENTION! Adjustments are to be completed equally for both right and left boom wings.



ATTENTION! The following types of arrows are used when describing the different boom adjustments:

Adjustment of Boom Tilt

The unfolded spray boom must be horizontal to begin with, before you start a spray job. If needed, horizontal adjustment of the boom wings is possible by adjusting the ram eye on the hydraulic tilt cylinders located on both sides of the sprayer.

NOTE! This boom can tilt down to max. 4 degrees below horizontal level (only if the AutoHeight function is installed).

Steps for adjustment:

ATTENTION! If the hydraulic cylinder is not being replaced, it is not necessary to disconnect the ram eye / hydraulic



cylinder from the boom to make the adjustments described in the following steps. Instead, the piston rod can be rotated by turning it with a wrench placed just behind the ram eye, without disconnecting the hydraulic cylinder from the boom.

1. Disconnect the ram eye from the boom wing.

2. Loosen nut (A) and the pin bolt inside. This will unlock the ram eye

from the cylinder’s piston rod.

3. Rotate the cylinder rod with a wrench fitted on the flat surfaces on the end of the ram eye (near A). This will move the ram eye in or out.

To raise the boom wing: Move the ram eye inwards.

To lower the boom wing: Move the ram eye outwards.

4. To be able to lock the ram eye to the piston rod after adjustment, turn the ram eye 1 full revolution at a time; this will move the ram eye approximately 1/16” (2 mm) in or out.

5. Reconnect the ram eye to the boom parts to check the horizontal level of the boom wing.

If further adjustment is needed, go back to step 3.

If horizontal alignment is OK, tighten the pin bolt and nut (A).

Adjustment is now completed.

6 - Maintenance

Horizontal Alignment of Inner Sections (Hydraulic Yaw)

This alignment is to compensate for the wind resistance when driving with an unfolded boom, as well as keeping a good balance in the boom when driving on uneven fields. The boom is adjusted relatively to the direction of driving.

Steps for adjustment:

1. Turn the stop bolt (A). Wrench = 30 mm.

• To bring the boom forward (B):

Turn the stop bolt counterclockwise and tighten the jam nut.

Torque = 185 Ft/lb (250 Nm).

• To bring the boom backward (C):

Loosen the jam nut and turn the stop bolt clockwise.

2. .Stand near the boom center and look towards the boom end. Compared to being on a perpendicular line to the direction of driving, the boom should now be adjusted a little forward (B).

The boom tip must be between 4” (100 mm) and 18” (450 mm) ahead of the perpendicular line.

Hydraulic Yaw

3. When the plunger cylinder (D) is fully pressurized, the piston stroke (E) must not exceed 1.5” (38 mm). Adjust the stop bolt (A) accordingly.

4. Adjustment is completed when the boom is aligned within the range mentioned in step 2. After aligning other boom sections, check if realigning is needed here.

6 - Maintenance

Accumulator Service

If the yaw damping seems to be insufficient, the accumulators need to be recharged or replaced. Ask your HARDI® dealer to assist you.

1. Check for any leaks.

2. Check pressure setting for the accumulators in the test sockets,

which are located in the hydraulic block below. Hydraulic hoses for the accumulators are also connected to this block.

3. Fill nitrogen gas (N pressure of 260 psi (18 bar) [factory setting]. The gas volume in the accumulator is approx. 0.5 quarts/liters.

4. Fill hydraulic oil until you reach a pressure of 500 psi (35 bar) in the accumulators [factory setting].

DANGER! Do not fill the accumulators with other gases, such as air or pure oxygen. Risk of explosion.

1. Loosen the 2 allen screws (1) on the link eye

2. Turn the threaded rod (2). Wrench=16mm

• To bring the boom forward (B):

Turn the threaded rod (2) counterclockwise and tighten allen screws (1).

Torque = 26 Ft/lb (35 Nm)

• To bring the boom backward (C):

Turn the threaded rod (2) clockwise and tighten the allen screws (1).

Torque = 26 Ft/lb (35 Nm)

ATTENTION! It is necessary to maintain 51/64” (20mm) of threads inside the link eye.



3. Stand near the boom center and look towards the boom end. Compared to being on a perpendicular line to the direction of driving, the boom should now be adjusted a little forward (B).

The boom tip must be between 4” (100 mm) and 18” (450 mm) ahead of the perpendicular line.

6 - Maintenance

ATTENTION! The hinge will move forward and backward during



the spray job; make sure that the threaded rod does not come in contact with the boom. Minimum distance is 5/8” (15mm).

ATTENTION! Make sure that there are threads showing outside of



the jamb nuts. If not you will run the risk of the boom coming free and swinging forward toward the tractor cab.

Mechanical End Stop

1. The mechanical end stop (1) must be adjusted so that it is placed in the middle of the folding arm.

• Loosen bolt (A) so that the end stop can slide freely.

• Adjust the position of the end stop by screwing or unscrewing bolt

(B).

• Tighten counter nut (C).

ATTENTION! Make sure that bolt (B) does not come completely



unscrewed from mechanical stop (1).

6 - Maintenance

Anti-Yaw Damping

1. Adjusting the damping on the Anti-Yaw is done by tightening or loosening the tension on either side of the rubber dampers.

• To make the damping tighter:

Loosen jamb nut (A), and tighten tensioner nut (B), making sure to retighten jamb nut (A).

• To make the damping looser:

Loosen jamb nut (A), and loosen tensioner nut (B), making sure to retighten jamb nut (A).

ATTENTION! When loosening up the tension on the dampeners, there should always be a tension load on the



dampers. They should never be loose.

NOTE. Factory adjustment is finger tight, then tighten the tensioning nuts another 10mm with a wrench.

6 - Maintenance

Vertical Alignment of Middle and Outer Sections

Steps for adjustment:

1. Start with the middle section, which is aligned with the inner section.

2. At the top of the boom, nuts (A, B) are adjusted. Wrench = 41 mm.

Raise the boom: Loosen (A), tighten (B).

Lower the boom: Loosen (B), tighten (A).

3. At the bottom of the boom, the ram eye (C) can be adjusted if needed. Remove the black pin (D), loosen the jam nut (E) and turn the ram eye 180°. Replace the black pin and check alignment of the boom section.

4. When the middle section is aligned, tighten all jam nuts.

Adjustment is completed when the alignment is straight, and the folding is trouble-free.

5. The outer section is aligned with the middle section in the same way by completing steps 2 & 4.

Adjustment of Boom Lock

Description of Boom Lock Mechanism

To prevent accidental folding of the spray boom while spraying, the boom joints interlock automatically when fully unfolded. The conical bolt (A) will guide the boom sections into the interlocking position.

A specially designed steel plate (B) will be lifted up, as the conical bolt (A) passes through the plate. The plate (B) will fall down behind the bolt head, thus securing the unfolded position.

When folding, a hydraulic cylinder (C) will temporarily pull up the steel plate (B) to allow the boom sections to separate.

NOTE! On the picture, the cylinder (C) is detached from the steel

plate (B). It must be attached during operation of the boom.

Horizontal Alignment of the Boom

The bolt (A) can be adjusted sideways as needed.

1. Loosen the lock nut (D). Wrench = 41 mm.

2. Turn lock bolt (A), until the boom sections align. Wrench = 46 mm.

6 - Maintenance

ATTENTION! The lock bolt is eccentric. Always turn it 1 full



revolution at a time; this will move the lock bolt 1/8” (3 mm) back or forth. Ensure that the lock bolt aligns with the center of the hole in the lock mechanism when the adjustment is completed.

3. Retighten the lock nut (D). Torque = 185 Ft/lb (250 Nm).

Adjustment completed.

Vertical Alignment of Breakaway Section

Align the breakaway with the outer section of the boom.

Steps for adjustment:

1. Loosen nut (A). Wrench = 24 mm.

2. Rotate turnbuckle (B). Wrench = 17 mm.

Turn clockwise: The breakaway is raised.

Turn counterclockwise: The breakaway is lowered.

3. When the breakaway is aligned, tighten nut (A)

Adjustment is completed.

6 - Maintenance

Horizontal Alignment of Breakaway Section

Complete the following steps to adjust the breakaway to align it with the outer section of the boom.

ATTENTION! Before making adjustments, Locktite 638 (or



equivalent) must be added between the bolt holes on bracket (B) to ensure that the bracket (B) does not move after adjustment.

1. There are four sets of bolts and nuts (A) in all, mounted in both sides of the steel bracket (B). Wrench = 17 mm.

In the picture, the bolt and nut are already removed from one hole. The slotted holes in the steel bracket allow adjustment. The steel bracket is attached to the breakaway

2. Align the breakaway with the outer section by moving the bracket.

3. Retighten the bolt and nuts. Torque = 130 Ft/lb (180 Nm).

Adjustment is completed.

Adjustment of Breakaway Section

Th e br eakaw ay se ctio n at t he b oom e nd wi ll mo ve b ack o r for th if it hi ts a stat iona ry obj ect ( e.g . a po le o r a tr ee) when driv ing with an unfolded spray boom. The spring on the outer section of the boom will pull the breakaway back into place when the boom is clear of the object. When spraying, the breakaway may also sway a little if driving on uneven ground.

The spring is preloaded from the factory - but adjustment is needed if:

• the breakaway is continuously swaying a lot due to a bumpy field (tighten the spring).

• the breakaway has become very hard to move by hand, when the sprayer is at a standstill (loosen the spring).

• reattachment is necessary due to replacement of the spring, cable or other parts.

Steps for adjustment:

A. Turn these nuts to adjust the spring.

B. Dimension of preload of the spring. Factory setting is 18-7/8” (480 mm). Maximum preload is 21-5/8” (550 mm).

WARNING! Risk of squeezing. Keep fingers and clothes away from the spring windings when adjusting the spring.

Alignment of Rubber Pads on Spray Boom

When the boom is folded, it must be checked that it rests correctly on the rubber pads. The rubber pads protect the boom parts during folding and transport, so please check them for misalignment. The rubber pads also help to steer the boom into the transport position.

Steps for adjustment:

1. Fold the boom and check the positions of the rubber pads (A). They must be touching, when folding is completed.

2. If realignment is needed, loosen the four lock nuts (B) slightly. Wrench = 17 mm.

3. Move steel bracket with the rubber pad sideways to the wanted position.

4. Tighten the four lock nuts to lock the position of the rubber pad.

5. Adjust other rubber pads on the boom as needed.

6 - Maintenance

Adjustment of Tilt Indicators

When tilting the spray boom for transport, there are indicators to ensure the correct height of the tilts. When correctly adjusted, the indicators will point to the very end of the tilt cylinder barrel so the entire spray boom can be set directly into transport after folding.

Steps for adjustment:

1. Fold the boom completely into transport.

2. Without activating the tilts, lift the spray boom via the main lift, unfold the inner fold and check that indicator (B) is

pointed at the end of the tilt cylinder barrel.

3. If not then it is necessary to loosen bolts (A) and reposition indicator (B) so that it is pointed at the end of the tilt cylinder barrel.

6 - Maintenance

Venting the Boom Hydraulics

If the hydraulic cylinders or hoses have been dismantled, it is necessary to vent the cylinders after reassembly.

DANGER! Failing to vent the hydraulic system when needed may result in violent boom movements and poor boom

€

performance. Risk of damage to the boom parts or foreign objects nearby. Risk of severe injuries or death.

ATTENTION! Not all hydraulic cylinders have a venting option. In this case you must loosen the hydraulic hose



connected to the cylinder to let the air out this way. Note that ORFS fittings are used - be careful not to damage the sealing O-ring, when venting oil.

ATTENTION! The following venting instructions are for double acting cylinders only. For single acting cylinders, such



as for the boom tilt motion, the venting is easily completed: After service, apply hydraulic pressure to the cylinder, retract and extend the piston approx. 5 times, and the air is then removed from the system automatically.

Sequence of Cylinders for Venting

To complete an efficient venting of air in the system, this sequence should be followed.

1. Boom center: Cylinders for inner sections on boom wings.

2. Boom wings: Cylinders for middle sections.

3. Boom wings: Cylinders for outer sections.

4. Boom center: Cylinder for slant motion.

Venting Procedure

Follow these steps to complete the venting. Both venting screws or valves (A and B) are closed to begin with.

1. Cylinder piston is retracted.

2. Remove the dust caps from the venting valves.

3. Mount a clear 5 mm hose to the venting valve (A) and lead it into

a suitable container.

4. Open the venting valve (A).

5. Activate the hydraulic oil pressure and extend the piston fully.

6. Close the venting valve (A) and remove the hose.

7. Mount the clear hose to the other venting valve (B).

8. Open the venting valve (B).

9. Activate the hydraulic oil pressure and retract the piston fully.

10. Close the venting valve (B) and remove the hose.

11. Repeat steps 3 - 10 a few times until air is no longer visible in the

hose.

12. Refit the dust caps. Venting is completed for this cylinder.

13. Check your hydraulic oil level - top up if needed.

DANGER! Be careful when operating the cylinders. Make sure that no unauthorized persons are in the working area,

€

when folding or unfolding the boom! When retracting the pistons into the cylinders, keep fingers, tools and clothes away from the piston. Risk of getting trapped between moving boom parts or folded boom sections resulting in severe injuries or death.

ATTENTION! Depending on the boom design, it might be more practical to begin with the cylinder extended.



ATTENTION! A helping hand is useful to complete the venting procedure.
