Introduction
The development of mobile access and working towers systems is from the following two roots:
— scaffold manufacturers placed prefabricated unanchored scaffolds on four legs and castors;
— ladder manufacturers began to construct mobile access towers with light-weight ladders using
aluminium frames and castors.
Taking this into account, CEN/TC53 decided in 1980 to standardize the manufacture of mobile access
and working towers in parallel with the European standardization of prefabricated service and working
scaffolds EN 12810-2 and EN 12811-3.
For materials, this document refers only to valid documents. However, a large stock of equipment made
of materials conforming to documents no longer valid is in use. This document does not cover this
equipment.
Attention is drawn to the requirements of the European Council Directive 2009/104/EC (provisions
concerning the use of work equipment provided for temporary work at a height).
The average height of people continues to increase and that consideration will have to be given in later
revisions to altering vertical dimensions.
The wind load requirements of this standard (0,1 kN/m ).
Consider the fact that mobile access towers are generally intended for shorter duration tasks and may
be re-located or quickly dismantled. Attention is drawn to 3.1, Note 2 and to the requirements of
EN 1298 regarding information relating to wind conditions.
Mobile access and working towers are not anchor points for personal fall arrest equipment unless they
are specifically designed in accordance with relevant European standards by the manufacturer for that
purpose.
1 Scope
This document applies to the design of mobile access and working towers made of prefabricated
elements with dimensions which are fixed by the design and with a height up to 12 m (indoors) and up
to 8 m (outdoors). This document applies to mobile access and working towers used as temporary work
equipment.
This document:
— gives guidelines for the choice of the main dimensions and stabilizing methods,
— gives safety and performance requirements, and
— gives information on complete towers.
This product standard does not apply to scaffolds according to EN 12810-1 and EN 12811-1.
