FASTENER SYSTEM

This system uses a profiles specially designed in order to bear 
heavy loads.The wide of these profiles and the thickness of their 
walls ensures a big firmness of the set. These profiles incorporate 
a rail with a serie of fixation holes where the security bolt are 
located. 
These holes have the sufficient size in order the bolts could be 
introduced quickly, providing the folding speed of the tower.

The security bolts have been

The pulley system (upper and lower on each profile) entrusts to transmit the generated strain 
in the winch and to elevate the profiles, for this reason, these pulleys disposes of an appropiate 
design in order to handle the cable, enclosing the whole system in a compact set.

PROFILE 2

The fastener system operates in following way:
We turn clockwise the winch that thighten the cable and thanks 
to the pulley system, the more outer profile is elevated. 

ALL SECURITY BOLTS MUST BE IN BLOCK POSITION

, 

so the elevation of the profile cause that the spring pin
of the bolt retracts, which triggers when a hole of the profile 
is located in paralell with it, blocking the tower in that position.

This situation is not 100% assured. The load could deploy an
intermediate section but the lifting process will restore the normal
unfolding.

For the descent, we must to unblock the lower security bolt and turn the winch on inverse 
sense, the load bring down the profile up to the stand position, in that moment we must 
to block the bolt for the transport use and we must unblock the new security bolt from 
the descended profile.
We proceed in the same way, with all profiles up to the total tower unfolding.

In this point, there is a strain in the cable in order 
to keep unfolded the pulley system, but all load is 
supported by the security bolts, releasing the winch
and give up using it.

We continue elevating the tower up to the security 
bolt locates in the las hole of the elevated profile. 
In that moment, the next profile is elevated 
identically up to total tower folding.
