Always try to increase the dimensions of the floor contact surface area. Close the two front clampson
on the stabilizer, making sure it rests firmly on the ground, and then tighten the corresponding eyebolt
nuts. Repeat the same sequence of operations for the other three tower uprights;
• As the tower is being assembled, pay careful attention to place the floor pieces in a position that
allows the person working at height the maximum possible safety and freedom of movement. The
person should have the possibility to anchor the safety belt worn easily;
• Once the tower has been assembled, fit the work platforms, toeboards and lateral protections at the
desired heights; make sure that the anti-lifting devices (hooks), located at the ends, are in the correct
position of the anti- detachment;
• The lateral protections are composed of 2 long frames and 2 short frames The two frames must be
fitted first, parallel to the long sides of the tower. Rest them on the cross-pieces of the load bearing
frames, making sure the top pipe is one meter from the walking surface. Install the short frames parallel
to the short side of the mobile access tower, hooking them up to the long guardrails at the top end,
and to the latches positioned on the latter at the bottom side;
• Once assembly is complete, insert the caps (packaged together with this manual, in the Wheel-bearing
section) in the terminal horizontal bracing, to preserve the scaffolding.
• For passage platform use the steel guardrail bar, with anti-detachment device at the ends. Place the
bars on the rung and make sure that the hooks are in the correct anti-detachment position.
• During assembly, to raise the components for the upper section, it is advisable to use ropes or cables
rated for the application, taking care never to pass up more than one component at a time;
• If access to the work platforms is to be gained by inclined rung or step ladders, these must be attached
with the two hooks at the top end to the cross piece on wich the work platform
DISASSEMBLY
• To dismantle the mobile access tower, follow the assembly instructions in reverse order;
• Lower mobile access tower components from above using ropes, cables or other suitable means,
avoiding at all times abrupt impact with the ground.
STABILITY
• Erect and use the mobile access towers only in the absence of windy conditions;
• Fit the stabilizers, based on the configuration and height to be reached.
• The maximum horizontal load capacity (e.g. applied by effect of work in progress in an adjacent
structure) is 25 kg, understood as the sum of the loads applied by the various operators working on
the tower;
• If the tower must be left unattended in position due to temporary interruption of work or windy
conditions, anchor it firmly to a fixed, stable structure;
