12. It is not permitted to push against adjacent objects (such as walls)
when working on mobile working platforms.
13. Lifting gear must not be attached to or used on mobile working
platforms.
14. Assembly and movement is only permitted on sufficiently strong
surfaces, and only in the longitudinal direction or diagonally. All impacts
must be avoided. If the base is widened on one side with wall bracing,
movement must always be parallel to the wall. Movement should not
be faster than normal walking pace.
15. No personnel and/or loose objects may be on the tower while it is
being moved.
16. After movement, the wheels must be locked by pressing down the
brake lever.
17. The towers must not be subjected to any aggressive fluids or gases.
18. Mobile working platforms must not be connected by bridging unless
a special verification of structural stability is provided. The same applies
to all special structures such as suspended scaffolding. The attachment
of any bridging elements between one mobile working platform and a
building is also not permitted.
19. When used in the open air, or in open buildings, the mobile
working platform must be moved to an area protected from the wind
or secured by other suitable means to prevent it falling over if the
wind strength exceeds 6 on the Beaufort scale, or at the end of the
working shift. (Wind that exceeds strength 6 can be recognized from
the difficulty felt when walking into the wind.) If possible, rolling towers
used outside buildings should be securely fastened to the building or to
some other structure. It is recommended that mobile working platforms
are anchored down if they are left unsupervised. The scaffolding must
be aligned perpendicular either by use of the compensating screw, or by
inserting suitable materials underneath. The permitted deviation from
the perpendicular must not be more than 1 %.
20. Decks can also be raised or lowered one rung in order to obtain a
different working height. In that case it is necessary to make sure that
the specified side protection heights of 1.0 m and 0.5 m are maintained.
When assembled this way, deck diagonals are to be used.
The manufacturer must be consulted regarding a stability
verification.
21. The access hatches must always be kept closed except when
climbing through them.
22. All couplers are to be tightened up to 50 Nm.
23. It is forbidden to climb over from rolling towers.
24. Jumping onto the deck surfaces is forbidden.
25. A check must be made on whether all the parts, auxiliary tools
and safety equipment (ropes etc.) needed for assembly of the mobile
working platforms are available on the building site.
26. Horizontal and vertical loads that could cause the mobile working
platform to tip over must be avoided. These include:
– forces caused by pushing against adjacent objects (e.g. walls)
– additional wind loads (the tunnel effect of buildings with through-
passages, buildings without facings or building corners).
27. Mobile beams, stabilizers or outriggers and ballast must be installed
if specified.
28. It is forbidden to increase the height of the deck surfaces by using
ladders, boxes or any other objects.
29. Mobile working platforms are not designed to be lifted or
suspended.
30. The item numbers for components given in blue in the text refer to
the list of individual parts on pages 27 – 29.
