2.0 USER MANUAL
2.1 TERMINOLOGY AND DEFINITIONS
Module:
The main part of the system that consists of a console to which the safety net is
assembled.
Console:
An element through which the net is assembled and formed. The console consists of
a universal assembly holder and a moveable arm.
Console's arm:
A moveable element consisting of two arms joined with a swivel joint. It allows to form
the shape of the safety net. The net and its edge line is assembled to the movable arms
and its edge line.
The universal assembly holder:
A holder used to assemble the moveable arm to the floor or the wall. It is also used in
case of the console's assembly adapters – “H” adapter. The holder allows to assemble
the moveable arm in lower configurations (see the Assembly Manual).
Stretching holder:
An additional holder used while attaching the net’s edge to the floor or wall –
depending on a given situation. That holder is used also during the assembly of the
stretches of the extreme consoles.
Assembly adapter “H”:
A device used to assemble the console to the elements of the construction. i.e. balks,
poles etc. in situations when there is no possibility to drill and perform other actions
that would interfere with the building's structure.
Net:
The net consists of two integrated nets of which one is used to catch large objects and the
other one (mosquito net) catches smaller elements. The net used in the system was designed
in accordance with the EN-1263- 1_2015-02E standard:
TYPE S, A2 Q100. It means that it is an A2-class net that absorbs min. 2300 J of
energy. The allowed maximum fall height for objects is below 2 m.
The net consists also of the edge line that works as an intermediate element carrying the
loads from the net to its outer edge and the carrying elements of the system.
Edge line:
Along the edge of the net there is an integrated polypropylene line (Ø12 and
the strength of 30 kN).
Stretching line (lace up):
A Ø8 polypropylene line for connecting the nets (lace up – see the assembly manual).
It is also used for adjusting the tension of the most extreme consoles.

2.2 PURPOSE AND SCOPE OF USAGE
The LiteMESH system is aimed at securing the outer edges of buildings and used as a
protection measure while performing works on lower levels and to secure
communication strings.
The net catches falling objects and protects people standing below.
The LiteMESH system is a connection of two nets with wide and small meshes. It catches both big
and small objects, and even semi-liquid elements. The system is characterised by an easy, universal
and quick assembly to the front and the upper part of a floor, as well as to a wall. Thanks to the
lightness and flexibility of the system, it is possible to adjust it to all building conditions.
The LiteMESH net is a quick and an affordable way to secure construction sites
and works which demand increasing the level of safety.
The use of the LiteMESH system is allowed only on condition that the user adheres to this
Technical Documentation, as well as the proper occupational safety and health regulations.
2.3 ALLOWED WORKING PARAMETERS
The LiteMESH system is a set of elements working together to protect users from falling. For
that reason and in order to use it in a safe manner, it is necessary to get familiar with the rules
of the system's operation and its limitations.
The maximum offset between the consoles: 6 m,
the maximum catching height 2 m,
the maximum distance between the edge line's holders: 3 m,
the nominal value of the energy absorbed by the net: 2,3 kJ.
