Du to the lenght of a
single elastic band (3,00 cm) it is possible to form an arch with a span of
250 cm with only one band. For spans over 250cm two elestic
bands connected with the supplied bolts on the middle support.are needed.
Double arch, diametre of 170 to 250 cm.
( 68 to 98 inches)
 | Make sure to place both Multiarcs on solid
ground. Bolt each on a square board of 50 cm ( 18" )minimum size
|
| Place the two Multiarcs in a straight line
at a distance, half the chosen arch diametre.(Diameter
240 cm = Axis 120) |
| Slide both the assemblies to the top of the
centre poles.
|
| Pull the triggers and rotate the inner arms
to the desired radius, that is half the diametre
|
| Remove the u-clamps from both inner arms.
|
| It is important that both arms are at the
same height. If not please ajust one of the centre poles.
|
| Hang the red ajoining device on the u-clamp
pin of the left clamp and close the handle.
|
| Hang the red ajoining device on the u-clamp
pin of the left clamp and close the handle.
|
| Now you have to join the two Multiarcs with
the red ajoining device. To do this, there is a trick: press the right
handle half way down and the plate can easily be put in position
|
| The „pre-tension" with the right
handle, makes it easy to slide the middle support to the desired rise.
Press down the handle fully to secure the support.
|
Tip: The rise of an
arch with an diametre between 170 and 250 cm (68" and 98")
should be approximately 15 to 20 per cent of the diametre.
| Mount the flexible band. Open the clamp
handles on the outer arms of the Multiarcs. Remove the u-clamps and fasten
the band.
   |
Tip: To make it
easier, rotate the arms to a 80 cm position. When you have fastened the
flexible band on both sides, rotate the arms to the desired diametre.
| Please make sure that the band is secured on
top of the middle support.
|
| Slide the assemblies down the centre poles
until the band touches the poles. This stabilizes the flexible band
|
| Adjust the height of the arch with the centre
poles. |
| Check if the Multiarcs are horizontal with a
lever. If not, adjust a centre pole. It is important that the centre poles
are a hundred per cent vertical! |
Double
arch, diametre of 250 to 340 cm.
(98 to 134 inches)
| Place the two Multiarcs in a straight line
at a distance of half the chosen arch diametre. (Diameter 300 cm = Axis 150 cm)
|
| Join the two flexible bands with the
supplied bolts on the middle support.
|
| Pull the triggers and rotate the inner arms
to the desired radius, that is half the diametre. Remove the two u-clamps.
It is important that the two arms are at the same height. If not, please adjust a centre pole.
|
| Slide both the assemblies to the top of the
centre poles.
|
| Hang the red ajoining device on the u-clamp
pin of the left clamp and close the handle.
|
| Slide the middle support between the two
arms and let it rest on the clamps.
|
| Press the right handle half way down and the
ajoining plate can easily be put in position
|
| The pre-tension with the right handle makes
it easy to slide the middle support to the desired rise. Press down the
handle fully to secure the middle support. |
Tip: The rise of an arch with an
diametre between 250 and 340 cm should be approximately 10 to 20 per cent of
the diametre.
| Align the flexible band to the desired
diametre on the outer arms and secure with the clamps.
|
| The final adjustment of the arch curve is
made by eye.
|
| Slide the assemblies down the centre poles,
until the band touches the poles. This stabilizes the supporting band.
|
| Adjust the height of the arch with the centre
poles.
|
| Check if the Multiarcs are horizontal with a
lever. If not, adjust one of the centre poles. It is important that the
centre poles are a hundred per cent vertical!
