USER MANUAL FOR WTS TOWERS
with one hand, the tower will descend until it is
locked.
Once the load is descended, block all sections
and follow steps 4 to 1 (in that order).

WARNING! If the tower is attempted
to go down without tension in the
cable and any of the safety systems
are activated, a dangerous situation will occur
because the load will descend very abruptly,
being able to destabilize the whole installation
and incurring in a serious accident.
USING THE TOWER IN
STRUCTURAL MODE (WIND
CONDITION)
The towers used in the structural mode form a
column type system that can withstand higher
loads than the mechanism mode.
In order to be able to use the towers outdoors
and subjected to bursts of wind, you should
contact an engineer in the area or our technical
department to study the case
In outdoor use many factors must be taken into
account, the most important are:
- Wind gusts
- Total exposed area
- Working height
- Angle of the braces
- Weights and distance to the tower
- Rigging of all joints
- Etc …
As an operating guide, the towers involved in this
manual can be used outdoors as long as they are
in structural mode and the maximum loads are
those of the mechanism mode.
This is because the loads transmitted by the
winds are transmitted vertically from the tower
to the ground, adding an overload that depends
on several factors. This overload is added to the
maximum load of the tower.
If it is not calculated in each specific case of use,
it is possible to take as base the data contained
in the load chart (figure 100) operating the
tower as mechanism for security purposes.
