4 Safety requirements and/or protective/risk reduction measures
4.1 General
Machinery shall comply with the safety requirements and/or protective/risk reduction measures of this
clause. In addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for
relevant, but not significant hazards, not dealt with by this document.
4.2 Calculations
4.2.1 Stresses
4.2.1.1 The lifting table shall be designed in accordance with usual calculation codes and good
engineering practice and all failure modes of the material shall be considered, including fatigue failure.
4.2.1.2 The stresses in any part of the lifting table assessed using the permissible stress method shall
not, under normal working conditions, exceed the lowest of the following values:
1) 0,66 times the yield stress of the material used; or
2) 0,50 times the ultimate tensile stress of the material used.
4.2.1.3 The stresses shall be calculated for a lifting table carrying its rated load and, if any, structural
load whilst being used in compliance with the instructions for use, see 6.3.
The loads shall include all real static and dynamic forces, both vertical and horizontal, any wind forces,
and all forces applied to the platform during loading and unloading. In case of extending part(s) of the
platform, the calculations shall consider the extension in the worst condition.
If wind forces are to be considered in the calculations, EN 280-1:2022, 4.2.3.3 shall be applied.
4.2.1.4 The minimum dynamic forces to be used for the calculations set out under 4.2.1.3 shall result
from:
1) the total vertical load (this includes the rated load and, if any, structural load, and the self-weight of
the moving parts of the structure) increased by the dynamic factor for the category of lifting table
shown in Table 1;
2) the horizontal load coefficient for the category of lifting table shown in Table 1, taken as acting
horizontally at the platform level in the direction causing the maximum stress in the part being
considered.

as part of AGVs.
When a lifting table is crossed by vehicles, or is integrated in a handling device, the lateral forces have to be
verified in individual cases. Higher horizontal load coefficients have to be established if required.
a
This minimum number of cycles shall be increased by the manufacturer according to the use of the lifting table.
b
When load cycle is used, in relation to lifting categories, the lifetime of lifting tables is generally 10 years when maintained
in accordance with the instructions for use.
c
Where skillet-lines or AGVs are used on uneven floors/driveways, the dynamic factor shall be increased to ensure that
the load bearing structure of the lifting table withstands the increased forces.
d
Horizontally moving lifting tables with high apex speeds, whilst turning, may require a higher value for the horizontal
load coefficient.
When determining the minimum dynamic forces used in the calculations, the following shall be taken into
consideration:
3) where rigid guarding prevents loading or unloading across a side, or other means prevent force
transmission to the platform in a particular direction, the horizontal load coefficient in this direction
need not be considered;
4) that lifting tables are classified in 7 categories (called lift category) depending on the use for which
they are designed. The dynamic factor, horizontal load coefficient and number of cycles used in the
design calculations shall be as defined in Table 1;
5) any likely wind forces, shall be in addition to the horizontal load coefficient calculations.
4.2.1.5 If operators and/or authorized persons are to be carried on the platform, their load shall be
taken as 80 kg, concentrated in an area of 0,2 m by 0,2 m for each person, spaced apart at 0,5 m centres
and placed in the most unfavourable position on the platform for stress and tilt calculations.
4.2.1.6 The use of the maintenance support(s) when applied according to the instructions fo use, see
6.3, shall not cause permanent deformation of the normal load bearing parts.
4.2.2 Platform deflection
When the lifting table is not designed for a specific loading, it shall be designed to meet all the following
load requirements (see Figure 1):
— firstly, the rated load evenly distributed over the usable platform area;
— secondly, half the rated load distributed over half the usable platform length or longest side of the
platform;
— finally, one third of the rated load distributed over half the usable platform width or shortest side of
the platform.
The load requirements shall be fulfilled when the platform is in the worst stressed position.
If the lifting table is driven by a scissor mechanism, the longest side is considered as the side parallel to
the scissor arms and the shortest side is considered as the side perpendicular to the scissor arms.
If the lifting table is driven by a non-scissor mechanism, the permissible loading configuration that the
machine is designed for shall be mentioned in the instructions for use (see 6.3.1).

In neither case shall hazardous, tilting or deflection take place when used as intended by design. The
maximum tilting or deflection shall not exceed that shown in Figure 2 where:
a) is the maximum tilting or deflection (y) of any side up to 2,0 m (l) long and is y = (1+ (2 − l)) %;
b) is the maximum tilting or deflection (y) of any side above 2,0 m (l) long and is y = 1,0 %.

4.2.3 Strength of the building/structure supporting the lifting table
The support (and, if appropriate, the load-bearing structure of the construction) to which the lifting table
is attached shall be built to withstand all the reasonably foreseeable static and dynamic vertical and
horizontal forces generated by both the load and the lifting table itself during normal operation and
exceptional operating conditions, e.g. anti-fall device operation.
The design shall address all dynamic forces and all externally imposed forces, including those caused by
load transfer on and off the platform and those caused by loading equipment.
These forces and loads are to be conveyed to the construction structural engineers on request to ensure
the construction is designed and built in a manner to support the lifting table and they shall be included
in the instructions for installation, as required in 6.4.6.
4.2.4 Stability
4.2.4.1 The calculated factor of safety shall not be less than 1,3. This shall be calculated by dividing
the sum of all the stabilizing moments by the sum of all the overturning moments, including the relevant
horizontal load coefficient as defined in 4.2.1.4. The overturning moments are to include all dynamic
forces and all externally imposed forces, including those caused by transfer on and off the platform and
those caused by operators and authorized persons as defined in 4.2.4.2. For this calculation the rated load
shall be evenly distributed over an area half the length times half the width of the platform, in any
overturning position.
If the lifting table is capable of tilting, the worst overturning position taking the tilt function into account
shall be considered.
In the case of mobile or movable lifting tables, it shall be considered that they are raising and lowering
on a slope of 2,5 % (1 in 40) in the worst direction for stability.
For these calculations it shall be considered that stabilizers are correctly set.

case overturning moment caused by
