To continue assembly of the tower, at this
point, at least one of the operators responsible
for assembly should wear a safety harness
and climb on the next work platform from
inside the tower through the specific trapdoor;
gradually, as the assembly operations proceed
of the tower, you should take care to position
the scaffolding in such a position to guarantee
the operator present at a height moves in an
agile and safe manner and has the possibility of
easily fastening the safety harness worn; once
assembly is complete of the tower, the work
platform should be positioned according to
instructions, at the desired heights, including
the toeboards and the side guards, locating
the two side protection battens correctly, i.e.
positioning the batten with a 50x22 profile over
the 4
th
rung and the batten with the 97x25 profile
over the 2
nd
rung compared to the work platform
and taking care to fasten the hooks placed on the
ends of the upright on the frame.
6.4 Dismantling instructions
Dismantling of the towers must take place by executing the necessary operations in the inverse
order to those for assembly; the elements composing the towers must be lowered from above
using ropes or other suitable devices, avoiding sudden impact with the ground.
7 STABILITY
a) The mobile access towers must be assembled and used only in the absence of wind;
b) the stabilizer braces must always be applied, based on the configuration and the height to
reach, as indicated;
c) the maximum applicable horizontal load, for example by effect of the work in progress
on an adjacent structure, is 25 kg, intended as the total of the loads applied by various
operators on the scaffolding;
d) mobile access towers left unsupervised due to temporary suspension of works or due to
the presence of wind, must be firmly fastened to a fixed, stable structure;
e) no additional structures must be added at the top of the tower and no screens of any
nature, such as timber frames, coverings or otherwise, should be mounted.
8 USE
8.1 Preliminary controls
a) Check the mobile access tower was assembled in a vertical position, regularly and
completely following the supplier’s instructions to guarantee state of the the art
implementation;
b) check no environmental changes can influence safe use of the access tower (frost, rain,
wind, ...).
