USER MANUAL FOR FT TOWERS 24

Figure 69
When the section reaches its end of path, lock
with the safety system and unlock the next safety
system to raise the next mast. Perform the same
operation until you reach the required height.
All safety systems must be in their locked
position. Slack the cable from the winch so that
the system is seated.
WARNING! The rate of rise and descend should
be similar. If the structure rises or descends
faster at one end, a destabilization of the entire
facility can occur, causing a serious accident.

To descend the load. Tense the cable and
unlock the first security system. Turn the winch
while keeping the safety system unlocked with
your other hand. If the safety system is not
operated with one hand, the tower will lower
until it is locked.
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.
Once the load is descended, block all sections
and follow steps 4 to 1.
