Étape 1 - Fitting of Mounting Channel 3

...Check with supervisor for correct handing and orientation of module and parts before commencing fitting

1 Fit mounting channels to frame using m12 Set bolts and A form washers.

Do not add adhesive to bolts at this stage . Do not tension bolts.

2 Set the first mounting channel to the middle of the adjustment slot at the extreme end of the frame

3 Place 2 meter straight edge between indicated points , and raise or lower point b to bring straight edge level with engineers level

4 Tighten bolts to hold in place

Étape 2 - Fitting of Mounting channel 2

1 Move channel 2 section up or down to copy height of adjacent channel 3. Use the tabs as the reference points

2 Use 2 meter straight edge and level between points indicated

Move channel 2 at the end indicated, to give a level reading

3 Tighten bolts to hold in place

Étape 3 - Fitting of mounting channel 1

1 Move channel 1 section up or down to copy height of adjacent channel 2. Use the tabs as the reference points

2 Use 2 meter straight edge and level between points indicated

Move channel 1 at the end indicated, to give a level reading

3 Tighten bolts to hold in place

Étape 4 - Quality Check Required

Once at this stage with mounting channels being set in position, a quality check is required from a Supervisor.

Étape 5 - Finalising Fixings

1 Remove Set bolt

2 Add adhesive Loctite 243 to bolt.

3 Refit and tighten

4 Mark head with ink to show completion of fixing

5 Repeat for all M12 fixings holding on mounting sections 1,2 and 3

Étape 6 - Dowel in Position

1 Drill 8mm Diameter holes in all roll pin holes situated between previous tightened m12 bolts ( 19 off in total reference detail 1 )

2 Insert 8mm x 24mm spiral pins to 8mm holes

3 Clean drilled areas of swarf and cutting fluid

Étape 7 - Mount support channels

1 Mount support channels to frame using m10 set bolts and m10 A form washers

Do not add adhesive at this point to fixings

2 Set all sections mid slot as per picture

3 Slightly tension bolts to hold in place

Étape 8 - Mount Support arms to frame

1 Support arm as shown in detail

2 Use 8mm x 25mm spiral spin to locate arm on mounting face

Use m10 cap heads with no washers to fix arm to mounting face

Use Loctite 243 to fix m10's and loosely secure arm to mounting face

3 Adjust arm for level on X axis by using the indicated face to check level with an engineers level

4 Tighten m10 cap heads to lock x axis position on arm and then ink mark bolts as finished

5 Adjust arm for level on Y axis. Use jack on pedestal to adjust height. Use engineers level on indicated point to check level

Étape 9 - Add support brace to Arm

1 Add brace to arm as indicted > bottom hole will need drilling into main frame to secure . Drill and tap M6. Position bottom of bracket to dimension shown

2 Repeat Step 8 to mount next arm onto frame.

3 The bottom position of the support brace is determined by the previous arm.

Measure Top pitch and replicate below

Étape 10 - Repeat step 8 and 9

Repeat step 8 and 9 to complete the mounting of the support arms

Leave the pedestal as support under beams 8 and 9

Étape 11 - Arm alignment

use following dokit for alignment

Alignment guide using wire line

Use support arms 1 and 7 as fixed datum points. The mounting section these are bolted to should be in the middle of their slot adjustment wise.

Set wire line and move indicated arms in directions shown to achieve straightness by wire line

Once alignment has been achieved, Check level of arms on Y axis and adjust if required by using pedestal stand and jack

Recheck alignment if arms have been adjusted on y axis , and correct if necessary

Étape 12 - Quality Check !

Supervisor sign off required for alignment

Étape 13 - Dowel and Fastener finalisation on arms 1 to 7

Secure m10 bolts at positions shown lightly, then drill 8mm diameter to top and bottom faces indicated then add 8mm x 25mm roll pins to drilled holes.

Repeat at all indicated points

Étape 14 - Ensure alignment of end sections

Now the arms are pinned at there local fix points, manipulate the two ends of the blue channel so they are in line with each other

repeat this step at both indicated points

Étape 15 - Drill final 8mm dowel points

Drill Final 8mm diameter holes at the remaining indicated points , top and bottom, and fit 8mm x 25mm roll pins

ow finalise all m10 bolts associated with each dowel , by removing one at a time, adding adhesive and then tightening to final tension. Then mark each bolt as complete with a pen mark.

Repeat this on all bolts next to dowels on the drilled blue section

Étape 16 - Finalise position of arms 8 and 9

Now a datum is set, arms 8 and 9 can be finalised

Arms 1 to 7 are used as the datum to set the position of these arms

Étape 17 - Set wire line and positions arms 8 and 9

Set up a wire line onto the indicated face , and use arms 1 to 7 for reference to set the alignment of arms 8 and 9.

Ensure slight gaps on arms 2 to 8 are maintained to ensure the straightness is held along the entire span of arms

Y axis position should be double checked when adjustment is complete for alignment of wire line, and adjusted to suit if required

Étape 18 - Quality Check required

Quality check from supervisor required at this point to assure correct setting of alignment of arms

Étape 19 - Drill and Dowel

Drill indicated remaining 8mm diameter holes next to arms 8 and 9 and fit 8mm roll pins .

Then finalise m10 bolts using the same process as before by removing one by one, adding adhesive and then tightening and marking as complete

Étape 20 - Alignment complete!
