6.1. General information
The erection of a mobile working scaffold may only be carried out if the safety instructions in
Chapter 2 "Safety instructions" have been read through completely and understood.
Therefore, first observe Chapter 2 and only then continue with the following instructions;
a) Scaffolds must be assembled, dismantled or altered under the supervision of a person in
charge and by workers who have received appropriate training for the operations
envisaged;
b) At least two people are always required for the assembly and dismantling of the mobile working
scaffold and it is essential that they are familiar with the assembly instructions and operating
limits;
c) During the assembly or disassembly of the mobile scaffold from a height of 2.00 m above the
ground, work platforms or scaffold planks of a size suitable for the dimensions of the deck must
be installed over the entire surface, to be used as a support surface for the assembly personnel;
d) Depending on the height to be achieved, one of the configurations given in Chapter 5 will
be chosen, where the weight of the structure and the quantity of the elements required for
assembly are also given.
CONFIGURATION OTHER THAN THOSE INDICATED IN THIS MANUAL, IN ORDER NOT TO
REDUCE THE STABILITY OF THE SCAFFOLD, WHETHER IN WORKING OR NON-WORKING
;
CONDITIONS
e) Railings, horizontal and diagonal beams are secured by means of quick-release fasteners that
snap into place during assembly and are therefore automatically secured against accidental
opening. To open the quick-release fasteners, the retaining bracket must be pressed against the
resistance of the existing spring;
f) During assembly work it must be ensured that the diagonal beams are always inserted from
above next to the side members, and the guardrails on the longitudinal side of the upper work
platform must be fixed laterally to the respective side panel uprights from the inside to the
outside;
g) The components of the mobile scaffold must be transported vertically (during assembly or
dismantling) using ropes or other suitable means, taking care never to lift more than one
component at a time and in any case avoiding sudden impacts of the components with the
ground;
h) All decks on the mobile scaffold, positioned in accordance with the instructions in Chapter 5,
even if they are used as walkways and not as working decks, must be fitted with side protection
(guardrails) and footboards.
6.2. Preliminary verifications
a) The surface on which the mobile working scaffold is mounted and moved must be able to bear
the weight of the scaffold and must be levelled to ensure that the load is evenly distributed
(check the tables on the weight of the structure and the maximum load on the work platform to
determine the total weight that is unloaded onto the ground);
b) The absence of any kind of obstacle must be ensured;
c) Mounting operations can only begin when there is no wind;
d) It must be verified that all components, any accessories, tools and safety equipment for erecting
the scaffold are available on site.
