RHA3-B3 boom adjustments

Linkage 1st section2nd section

Linkage2nd section3rd section

Use a wrench with a tube to tighten the bolts to maximum.

To start the adjustments of the RHA3-B3 boom,go from the linkage 2nd - 3rd section.

Before adjusting the boom, tighten all the bolts at the hinge points.

1/ Unfold the boom and remove the bolt at the cylinder rod end as well as the bolt of the double ball joint.

3

2/ Ensure that the 2nd and 3rd arms are perfectly horizontal by tightening or loosening the two ball joints A and B.

Tighten the ball joint nuts very slightly once the boom is perfectly horizontal.

3/ Fold up the boom by hand in order to make the 3rd section gently rest in its bracket on the 2nd section.

Adjustment too low Correct adjustment Adjustment too high

At the same time, pre-adjust the two stops C and D between the 2nd and the 3rd arms in order to have the boom well straight.

4

5/ Adjust the stop E of the hinge arm.

For that, disalign the 3 articulation points.L=20mm

When the stop E is correctly adjusted, you can tighten the nuts of the stop.

4/ If the 3rd section is too high, unfold the boom again and without disturbing the horizontal setting of the two arms, play on the two ball joints A and B. You must bring the 3rd arm closer to the 2nd arm.

On the other side, if when the boom is folded up, the 3rd arm is too low, you must move the 3rd arm away from the 2nd arm.

When the 3rd arm sits correctly on its bracket, you can tighten the ball joint nuts. We recommand to use an extension tube at the end of the wrench to ensure a good tightening of the nuts.

Check again the alignment of the boom in refining the adjustment of the stops C and D.

VERY IMPORTANT- STOP D SHOULD BE TOUCHING THE OTHER SECTION.

- THERE SHOULD BE A 2MM GAP BETWEEN STOP C

AND THE ALUMINUM.

STRONGtightening 6/ Adjustment of the double ball joint

Reattach the double ball joint on the hinge arm by reducing or increasing the distance «X» (see next picture), then tighten strongly the bolt.

To ensure a good hold of the boom for working, we advise you a manual adjustment of the linkage.

a/ Stand on the opposite side from theclosing direction and increase the distance «X» of the double ball joint.The increasing of the length «X» means a distance from the stop E to his contact point.

NoteA gap of a few centimeters is

really important.It determinates the locking effort.

b/ Pull on the hinge arm in leaning on the boom.The tractive effort on the unfolding armmust be important.When the locking is occuring, a clack of the stop E against its support gets along.

6

Once the locking done, make sure again that the boom is well aligned, otherwise adjust again stops C and D.

c/ Unlock the hinge arm and increase thedistance «X» of the double ball joint abouthalf turn, then tighten very strongly the locknuts.

Tightening of the counternuts of the

double ball joint

STRONGtightening

Turn the cylinder rod couterclockwise with a flat wrenche

7/ Adjustment of the cylinder rod.

a/ Extend hydraulically to the maximum the cylinder rod and screw the ball joint to the maximum too.

b/ Reattach the cylinder rod on the hinge arm, tighten strongly the bolt.The stop E is no more in contact. Look at the gap between the stop and the head of the screw.

c/ Unscrew the ball joint in order to have the stop E in contact.For that, fold slightly hydraulically the 2nd section to access to the adjustment of the ball joint.Turn the cylinder rod in the anti-clockwisedirection.CAUTION!! Make it gradually.

Put again hydraulic pressure in the cylinder to unfold the boom.

7

Slightbuckling

Stop in contact

You can now start the adjustment of the 2nd section with the 1st one.

To this end, resume all the previous steps:

1/ Seperate all the elements (step 1)2/ Line up the sections (step 2)3-4/ Adjust the height of the sections while folding (step 3-4)5/ Adjust the stop (step 5)6/ Adjust the double ball joint (step 6)7/ Adjust the cylinder rod (step 7)

Once the contact of the stop E is done,fold up slightly the 2nd section.

Turn again the cylinder rod (step c) until you can see a small buckling of the cyl-inder rod (the buckling corresponds ap-proximately to a 2-3mm additional stroke of the rod).

Now tighten strongly the locknut of theball joint.

8/ If your boom has a hydraulic sensorbetween the 1st and the 2nd section, adjust the stop F. This one must pressthe push-piece of the sensor.

CAUTION!! The push-piece must not be crushed, let a 2mm gap.

8/ If your boom has a hydraulic sensorbetween the 1st and the 2nd section, adjust the stop F. This one must pressthe push-piece of the sensor.

CAUTION!! The push-piece must not be crushed, leave a 2mm gap.

Maintenance & care of your aluminium boom

Weekly checks

Bolts and nuts checking

-Check that all the bolts and nuts are correctly tightened or tighten if necessary with suitable tools (wrench with 1 meter long extension bar).

Springs

-Check the tension of the breakaway spring. The tension of the spring is its zero state plus 100mm.

Lubrication-Lubrication of all linkage points (15 Lubrication points along the boom)and all ball joints and pin joints.
