with 3-part side protection.
12. When working on mobile working platforms, it is not allowed to
push against adjacent objects (e.g. wall).
13. Lifting gear must not be attached to and used on mobile working
platforms.
14. Assembly and movement are only permitted on sufficiently firm
ground, and only in a longitudinal or diagonal direction. Avoid any
impacts. When the base is extended on one side with wall bracing,
movement is only permissible parallel to the wall. During movement,
do not exceed normal walking speed.
15. No personnel and/or loose objects may be on the tower while it is
being moved.
16. After movement, lock the castors by pressing down the brake lever.
17. The scaffolding structures must not be subjected to any aggressive
fluids or gases.
18. Mobile working platforms must not be connected by bridging unless
its structural strength has been specifically verified. The same applies
for all other special assemblies, e.g. suspended scaffolding etc. Fur-
thermore, the provision of bridging parts between a mobile working
platform and a building is not permissible.
19.
When the mobile working platform is used outdoors or in open
buildings, it must be moved to a wind-protected area when wind
strengths exceed 6 on the Beaufort scale or at the end of a shift, or
secured against toppling over by other suitable measures.
(a wind
strength of more than 6 can be recognized by noticeable difficulty in
walking.) If possible, towers used outside buildings must be securely
fastened to the building itself or to other structures. It is recommended
that mobile working platforms be anchored if they are left unattended.
Set the tower to the perpendicular using the adjustable baseplates or
by inserting suitable materials underneath it. The maximum divergence
from the perpendicular is 1 %.
20. Decks can also be fixed one rung higher or lower to achieve a dif-
ferent working height. Care must be taken that the specified side pro-
tection heights of 1.0 m and 0.5 m are complied with. Deck diagonal
braces must be used in this assembly form.
21. The access hatches must be kept shut whenever they are not in use.
22. All couplers must be tightened with 50 Nm.
23. Climbing over from rolling towers is prohibited.
24. Jumping onto decked surfaces is prohibited.
25. Check that all parts, auxiliary tools and safety equipment (ropes etc.)
for assembling the mobile working platforms are available at the site.
26. Horizontal and vertical loads that can cause the mobile working
platform to topple over should be avoided, for example:
– pushing against adjacent objects (e.g. wall)
– additional wind loads (tunnel effect of through-type buildings, unclad
buildings and corners).
27. If stipulated, mobile beams or stabilizers or outriggers and ballast
must be provided.
28. It is prohibited to increase the height of the deck using ladders,
boxes or other makeshifts.
29. Mobile working platforms are not designed to be lifted or suspend-
ed.
