USER MANUAL FOR WTS TOWERS
Figure 75
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.
Figure 76
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.
Figure 77
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 descend 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.
