EN 1570-2:2016 (E) 4 European foreword This document (EN 1570-2:2016) has been prepared by Technical Committee CEN/TC 10 “Lilts, escalators and moving walks”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2017, and conflicting national standards shall be withdrawn at the latest by May 2017. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports the essential requirements of 2006/42/EU. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN
shall not be held responsible for identifying any or all such patent rights. For the relationship with EU Directive, see informative Annex ZA, which is an integral part of this document. According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1570-2:2017



EN 1570-2:2016 (E) 5 Introduction This European Standard document was drafted as a design guidance manual to provide a means of achieving conformance to the essential safety requirements stipulated under Machinery Directive 2006/42/EC. The machines concerned and the extent to which hazards, hazardous situations and hazardous incidents are covered are indicated in the scope of this European Standard. In addition, the machines should be designed according to the principles of EN ISO 12100 for relevant but non significant hazards, which are not dealt with in this standard. As lifting tables are used in a wide range of applications, it is equally necessary to perform individual risk assessments in accordance with EN ISO 12100 for the actual operating conditions. Products sold indirectly to end-users should be built to cover all the risks related to the use and all conditions foreseeable by the manufacturer, as described in the instruction manual. Where the text gives an example of a safety measure for the purposes of greater clarity, this should not be considered as the only possible solution. Any other solution leading to the same risk reduction is permissible if an equivalent or increased level of safety is achieved. While drafting this European Standard document, it was assumed that:
the lifting tables are only operated by persons trained in using the equipment in accordance with the manufacturer's instructions, and that the working area is adequately lit;
the lifting tables are installed on hard-standing, even, appropriately prepared surfaces.
where there are special requirements on low noise levels, such as for hospital applications and theatres etc., the customer should specify these requirements and the manufacturer should then take all appropriate measures. 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. SIST EN 1570-2:2017



EN 1570-2:2016 (E) 6 1 Scope 1.1 This European Standard specifies the safety requirements applicable to lifting tables presenting the following characteristics: — serving more than two fixed landings of a construction; — able to pass landings; — designed exclusively for lifting or lowering goods and not persons; — only accessible to persons during the loading/unloading phases; — with a travel speed of no more than 0,15 m/s; — permanently installed. 1.2 This European Standard deals with all significant hazards pertinent, with the exception of noise, to lifting tables when used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical measures for eliminating and reducing the risks arising from the significant hazards. 1.3 This European Standard does not apply to the following equipment: — permanently installed lifting tables, serving specific levels of a construction, with a vertical travel speed exceeding 0,15 m/s (EN 81-31); — lifting tables serving not more than two fixed landings of a construction (EN 1570-1); — lifting tables, serving more than 2 fixed landings of a construction for lifting operators, with a vertical travel speed not exceeding 0,15 m/s; — lifting tables carrying operators and installed in enclosures with a vertical travel speed not exceeding 0,15 m/s; — lifting tables used on ships; — lifting tables designed for artists and stage set features during artistic performances; — lifting tables driven by pusher chains. 1.4 This European Standard does not establish the additional requirements for: — electromagnetic compatibility; — operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields); — operation subject to special rules (e.g. potentially explosive atmospheres, mines); — handling of loads, the nature of which could lead to dangerous situations (e.g. molten metal, acids, radiating materials, particularly brittle loads, loose loads (gravel, tubes)); — hazards occurring during construction, transportation and disposal; SIST EN 1570-2:2017



EN 1570-2:2016 (E) 7 — equipment installed on the load platform or the replacing or maintaining of it; — integration into broader systems or other machines, etc.; — cable-less controls; — lifting tables where the hydraulic pressure is derived directly from gas pressure; — lifting tables powered by internal combustion engines. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

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 use of the lifting table. b When used (load cycle) according to lifting categories, the lifetime of lifting tables is generally 10 years when maintained in accordance with the manufacturer's instructions. NOTE 1 If permanent protection prevents 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. NOTE 2 Lifting tables are classified in 5 categories (called lift category) depending on the use for which it is designed. The dynamic factor, horizontal load coefficient and number of cycles used in the design calculations are defined in Table 1. 5.2.1.5 It shall be possible for the forces produced when the mechanical 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. 5.2.2 Platform deflection All lifting tables shall be designed to meet the following minimum requirements: a) in one case, lift half the rated load distributed over half the length or longest side of the platform; b) and in another case, lift one third of the rated load distributed over half the width or shortest side of the platform.

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