2Assembly and use
2.5 Positioning of the Stairway Tower
Sureface
Always place the scaffolding a stable and horizontal surface. Make sure that the scaffolding cannot
sink into the ground. In addition, the general slope of the surface may not be steeper than 1 degree.
So, at a height of 4 meters, the deviation may amount to a maximum of 4 cm.
Obstacles
Position the scaffolding in such a way that no danger to the user can arise when descending. Pay
attention to obstacles on the ground and/or obstacles at height.
Maximum height
This depends on the placement and type of scaffolding (see Table 1).
Tabel 1. Maximum Height.
* This is the maximum platform height; it only applies to scaffolds with stabilizers (not fixed).
Anchor the tower every 4 meters. There are several possibilities for anchoring which may vary
depending on the situation. The method of anchoring should always be determined on site by an
expert (the most common method is steel wall anchors in combination with screw eyes).
Weather conditions
Consult the weather report to determine safety in various weather conditions. Consider the following
conditions and use common sense. At wind force 6 or higher a scaffold may not be used.
Also, any materials such as canvas that are installed must be removed.
Precipitation
Remove snow and ice from the scaffolding before starting work. If necessary, sprinkle sand on the
work floor to prevent slippage.
Cold
Avoid using Stairway Tower at temperatures below freezing.
2.6 Personal protection equipment
•Always wear work gloves, safety shoes and a safety helmet.
•When working at height, use a life-line.

2.7 Assembly
For checking for damage: see section 3.
There are no tools required for assembling a Stairway Tower. For Staiway Towers from five meters
onwards, it can be useful to use a rope (with or without an accessory) to lift the components.
2.8 Assembly Instructions
1. Sort the diagonal (8) and horizontal (7) braces by length. Check that all materials meet the annual
inspection labels and inspect all materials for damage. If in doubt, contact ASC or your dealer with
any questions. Aluminum Scaffolding must only be assembled by people with sufficient and
proven experience.
2. Insert the wheel uprights (10) with casters into the frame (1) (without locking pins) along the
bottom edge. Apply the brakes evenly to the wheels.
3. Attach a horizontal brace (6) on its side to the upright and allow the brace
to rest on the ground.
4. Now click the horizontal brace to the other
frame, both frames will now stand.
5. Place the diagonal brace (8) on the 2nd rung of the frame and click on the 6th
rung of the opposite frame. A cross is now formed.
6. Place the stairway (4) from the opening in the (walkthrough) frame (1) to the
other frame.
7. The base section must now be leveled and, if necessary, adjusted with the adjustable wheel
uprights (by turning the nut) The maximum angle of inclination is 1%.
8. Place the stabilizers (11) and make sure they are firmly on the ground, always place a stabilizer
linkage under a rung (against shifting) It is recommended to use 4 pieces, but in any case use 2.
9. Place the inner guardrail (5) on the Stairway Tower. Secure it with the
locking clips.
10. Place the next two frames (1) on the base frames and secure the
frame with a locking clip.
11. Place the guardrail outside (6) on the inside of the (walkthrough) frame.
Check all components (use the list of components) that are required for assembly,
are present and undamaged. Damaged components should not be used.

12. Place the platform (3) on the 7e rung of the base-section. The platform will be
next to the stairway.
13. Repeat steps 9 to 13 until the desired height is achieved. Raise the parts using a rope.
14. Now install the double horizontal brace (with foldable frame) (9) next to the platform on at hip
and knee height.
15. Finally place the side board holders to the upright (just below the clips) on the top work floor and
place the side boards (or kick edges) in the slots of the side board holders.
2.9 Use
Extension/increase
Never elevate the scaffolding with a tool. Therefore, do not use stairs, ladders, crates or steps on the
scaffolding unless the stairs or ladder are intended to be part of the scaffolding.
Maximum permissible weight
Please read on the sticker on the platform what the maximum load is. Each ASC Group scaffold may
be loaded to a maximum of 200 kg/m2 and never more than 375 kg in total. This means on average:
two people with (hand) tools. The maximum horizontal load is 30 kg.
Stabilization
Stabilizers must always be installed. Stabilizers are supplied in an
adjustable version.
They are placed on a scaffolding which is placed against a building as
shown in figure A and a freestanding scaffold as shown in figure B.
Sideboard set
Sideboards are always required on the platform being worked on.
Security
Do not leave a stairway tower unattended in a public place for an extended period. If this is
nevertheless necessary, the scaffolding can be secured to a fixed object with a ring lock. To do this,
put the ring lock through one of the frame's compartments and attach an anti-climb device.
Before use, please check that:
•All parts are still present
•All the parts are still properly attached
•The tower is still perpendicular
•The stairway tower is clean
•There are any changes in the surroundings which may affect safe use
•The brakes are working on the wheel
•The stabilizers are touching the ground
•All locking clips are correctly in place
Never use a Stairway Tower near
non-insulated, electrical installations or machinery.

Relocation
A stairway tower can be moved by dismantling and rebuilding it. After moving the scaffolding, it must
be put back into plumb; therefore, go through the checklist again from Section 2.9.
2.10 Chemical products
3Inspection, care and maintenance
According to the regulations one must work safely at heights. On an ASC Mobile Tower, it is not
obligatory to wear extra fall protection (provided that the recommendations in this manual have
been followed).
3.1 The Health and Safety Law
The Working Conditions Decree is a concrete elaboration of the Safe Working at Height Act. It states
that everything above 2.50 meters is 'working at height' and is therefore a situation with increased
risk of injury. This also means that all materials must be properly manufactured and checked in a
quality cycle. ASC tests all materials and performs strength calculations. The user must also have the
material inspected annually for defects.
Annual control
Your ASC Mobile Tower must be inspected for any defects annually by an expert. The ASC Group can
perform this control for you.
Self-inspection
The ASC Mobile Tower can be inspected by yourself. Before each use, always check the components
for any damage. We certainly recommend larger companies to do a monthly inspection of all
components of the Mobile Towers and to record this inspection. If you are in doubt about damage,
consult an accredited inspector.
Damages
Examples of the most common damages on aluminium scaffolding;
•Components: if a claw or a sport is loose, the mobile scaffolding must be rejected.
•Dents and or holes: if there is a big dent in the aluminium or even a crack or hole, the
scaffolding must be rejected.
•Contamination: if there is too much concrete, paint or other non-removable contamination
on the components, the scaffolding must be rejected; after all, you can no longer judge
whether the components are still intact.
What to do in the event of damage
If there is any damage, which cannot be repaired, the component must be taken out and replaced. If
repairing is possible, please contact ASC Group for further information.
Avoid contact with acids and chemical products. These can cause corrosion to
the aluminium, which can affect the strength of the aluminium.

Repair
3.2 Transport
•Always transport the components in accordance with the locally applicable legislation.
•Stack the components correctly for transport; never place the heavy components on top.
•Transport the components of a scaffolding, preferably standing, f.e in a carrier.
•Handle the material with care. Do not drop components onto a hard surface; this can reduce
the quality of the material.
3.3 Maintenance
•Make sure the scaffolding material is clean, especially the connecting pins. The frames should
go in and out easily.
•Make sure the pawl of the hook of the diagonal and horizontal braces is clean. If necessary,
lubricate it with a little oil. The same applies to the wheel spindle.
•Replace missing and broken parts in time.
3.4 Storage
Store components of the scaffolding preferably in a dry, clean, dark and frost-free place.
Repairing a component must be carried out by a certified body or person.
