Foreword
This document (prEN 1570:2006) has been prepared by Technical Committee CEN/TC 98 “Lifting
platforms”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1570:1998.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA which is an integral part of this

Introduction
This standard is a Type C standard as stated in EN 12100.
This standard has been prepared to be a harmonized standard to provide one means of conforming
with the Essential Safety Requirements of the Machinery Directive and associated EFTA Regulations.
The extent to which hazards are covered is indicated in the scope of this standard. In addition, lifting
tables should comply as appropriate with EN 12100 for hazards which are not covered in this
standard.
Where, for clarity, an example of a safety measure is given in the text this shall not be considered as
the only possible solution. Any other solution leading to the same risk reduction is permissible if an
equivalent level of safety is achieved.
While producing this standard it was assumed that where there is a special requirement for a low
noise level, e. g. hospital applications, theatre applications etc. this will be specified by the customer
and appropriate measures taken by the manufacturer.
While producing this standard, it was assumed that only trained persons using the equipment in
accordance with manufacturers instructions operate the lifting tables and that the working area is
adequately lit.

1 Scope
1.1 This European Standard specifies the safety requirements for lifting tables for raising and/or
lowering goods and/or persons associated with the movement of goods carried by the lifting table (i. e.
not for passenger use).
1.2 This European Standard deals with all significant hazards pertinent to lifting tables when they
are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This
European Standard specifies the appropriate technical measures to eliminate or reduce the risks
arising from the significant hazards.
1.3 Both power operated and manually operated lifting tables are included whether stationary or
mobile.
1.4 This European Standard does not apply to the following equipment:
 permanently installed lifting tables, serving specific levels of a building and fitted with a car;
 lifting tables whose travel speed exceeds 0,15 m/s (unless safe by position and non person
carrying);
 power operated lifting platforms for persons with impaired mobility;
 mobile lifting tables for airport ground support equipment;
 lifting tables used as part of a lift under the “Lift Directive”;
 lifting tables used on ships;

 mobile lifting tables with a horizontal travelling speed of more than 1,6 m/s;
 rail dependent storage and retrieval equipment;
 theatre stage lifts;
 scissor lift pallet trucks;
 suspended lifting tables.
1.5 This standard does not consider the power supply to the lifting table by internal combustion
engine.
This standard does not establish the additional requirements for:
 operation in severe conditions (e. g. extreme climates, freezer applications, strong magnetic
fields);
 operation subject to special rules (e. g. potentially explosive atmospheres, mines);
6

---------------------- Page: 7 ----------------------
prEN 1570:2006 (E)
 handling of loads, the nature of which could lead to dangerous situations (e. g. molten metal,
acids, radiating materials, especially brittle loads);
 hazards occurring during construction, transportation and disposal;
 equipment installed on the load platform or replacing it;
 integration into systems or other machines, control from more than two control stations, etc.;
 cable-less controls;
 lifting tables where the hydraulic pressure is derived directly from gas pressure.

5 Safety requirements
5.1 Calculations
5.1.1 Stress
5.1.1.1 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.
5.1.1.2 The stresses in any part of the lifting table using the permissible stress method, under
normal working conditions, shall not exceed the lower of the following:
13

---------------------- Page: 14 ----------------------
prEN 1570:2006 (E)
a) 0,66 times the yield stress of the material used, or;
b) 0,50 times the ultimate tensile stress of the material used.
5.1.1.3 The stresses shall be calculated for the condition of the lifting table carrying its rated load
and being used in accordance with the manufacturers instructions.
The loads shall include all actual static and dynamic forces both vertical and horizontal, all wind forces,
and all forces applied to the platform during loading and unloading.
5.1.1.4 The minimum dynamic forces to be used for the calculations of 5.1.1.3 shall result from
either:
a) the total vertical load (this includes the rated load and the self weight of the moving parts of the
structure) increased by 40 % and;
b) 10 % of the rated load taken as acting horizontally at the platform level, in the direction causing
the maximum stress in the part being considered.
If side barriers prevent movement of the load in a particular direction this direction need not be
considered.
or alternatively lifting tables may be also allocated to the following categories:
Lifting
Examples of use
category
Lifting tables with a clearly defined lifting load and
1 1,1 2,5 % 8 where other forces can be excluded; height
adjustment without systematic lateral forces.
Lifting tables suited for the use of manual work; e. g.
2 1,2 5,0 % 32
adjustable height work station
Lifting tables suited for crossing with, e. g. manually
operated industrial trucks, electric pallet-stacking
3 1,3 10 % 128
trucks with a maximum braking of 10 %.
Lifting tables with mounted gravity conveyors.
Lifting tables suited for passing with, e. g. power-driven
industrial trucks, electric pallet-stacking truck with a
4 1,4 20 % 512
maximum braking of 20 %.
Lifting tables with mounted powered conveyors.
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.

5.1.1.5 If 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 centre to centre
and placed in the most unfavourable position on the platform for stress calculations.

accepted without permanent deformation of the normal load bearing parts, when used in accordance
with the manufacturer’s instructions.
