Part 1 of this standard deals with the protection at landings and safety requirements of lifting tables serving up to two fixed landings. Part 2 will deal with slow lifting tables serving more than 2 fixed landings for accessible only goods lifts and Part 3 will deal with slow lifting tables serving more than 2 fixed landings for operator carrying lifts. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
As lifting tables are used in a wide range of applications it is also essential to make individual risk assessments in accordance with EN ISO 12100 for the actual operating conditions. Products sold indirectly to end users should be made for all the risks, which are related to the use and conditions foreseen by the manufacturer, as described in the instruction manual. While producing this standard, it was assumed that:  only trained operators using the equipment in accordance with manufacturers instructions operate the lifting tables and that the working area is adequately lit;  lifting tables are operating on substantially firm, smooth, even and prepared surfaces. It is not necessary to consider centrifugal forces specifically as the current requirements consider all lateral forces;  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. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

5.1 General
5.1.1 Introduction Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards, which are not dealt with by this standard. 5.1.2 Calculations Calculations for stress shall meet the following requirements: 5.1.2.1 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. 5.1.2.2 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 unless stated otherwise: a) 0,66 times the yield stress of the material used or b) 0,5 times the ultimate tensile stress of the material used. 5.1.2.3 The stresses shall be calculated for the condition of the lifting table carrying its rated load and being used in accordance with the manufacturer's 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. 5.1.2.4 The minimum dynamic forces to be used for the calculations of 5.1.2.3 shall result from
 the total vertical load (this includes the rated load and the self weight of the moving parts of the structure) increased by the dynamic factor for the category of lift shown in Table 2 and  the horizontal load coefficient for the category of lift shown in Table 2 taken as acting horizontally at the platform level, in the direction causing the maximum stress in the part being considered. NOTE 1 If barriers prevent loading or unloading across a side, or other means prevent movement of the platform in a particular direction, the horizontal load coefficient in this direction need not be considered.

Lifting tables with mounted gravity conveyors. 5 1,4 10 % 512 Lifting tables suited for a high number of cycles 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 purpose of use of the lifting table. b When used (load cycle) according to lifting categories lifetime of lifting tables is generally 10 years when maintained in accordance with the manufacturers instructions.
NOTE 2 If barriers prevent loading or unloading across a side, or other means prevent movement of the platform in a particular direction, the horizontal load coefficient in this direction need not be considered. 5.1.2.5 If operators 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 operator, spaced apart at 0,5 m centre to centre and placed in the most unfavourable position on the platform for stress calculations. 5.1.2.6 It shall be possible for the forces produced when the safety device is operated, to be accepted without permanent deformation of the normal load bearing parts, when used in accordance with the manufacturer’s instructions. 5.1.2.7 Platform deflection 5.1.2.7.1 When the lifting table is not designed for a specific loading, it shall be designed to meet the following requirements:  in one case lift half the rated load distributed over half the length or longest side of the platform;  and in another case lift one third of the rated load distributed over half the width or shortest side of the platform.

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 5.1.2.4. 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. 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. SIST EN 1570-1:2012

5.2.2.1 General As an alternative to minimum gaps defined in 5.2.1, the travel zone below the platform may be protected by the following measures which are summarised in Table 3. These are minimum measures and should not be considered as the only method of protection, alternative methods offering an equivalent or higher level of safety may be used. SIST EN 1570-1:2012
