The requirement concerning loading control is not deemed pertinent to this standard insofar as:  experience and the state of the art suggests that failing to observe this requirement has not historically given rise to unsafe situations;  such devices which would give protection against overall and local overloading are not currently available in forms which cover all eventualities;  the weight and weight distribution is freely available for the type of vehicles to be lifted and as such it is the responsibility of the user to prevent an unsafe situation arising;  vehicle lifts are generally designed to suit the maximum weight of vehicle to which it would reasonably be subjected, hence the normal duty of a lift is substantially lower than the maximum.
NOTE 1 The guidance of the load carrying device is given by the supporting structure. NOTE 2 A vehicle lift may have the ability to tilt the load carrying device about a horizontal axis parallel to or perpendicular to the main axis of the lifted vehicle. NOTE 3 The following types of vehicle lift are examples of those covered by this definition: single and multi-column lifts, single and multi-cylinder lifts, mobile column lifts, scissor and parallelogram lifts, short stroke lifts, which support vehicle wheels, chassis or other designated lifting points (see Annex B (informative)). NOTE 4 Short stroke lifts are floor mounted vehicle lifts with a maximum vertical travel of not more than 500 mm, which are not designed for working under the raised load. 3.2 manually driven vehicle lift vehicle lift where the load carrying device is driven by manual effort 3.3 power-driven vehicle lift vehicle lift where the load carrying device is not driven by manual effort 3.4 fixed vehicle lift vehicle lift fixed permanently to its location 3.5 movable vehicle lift vehicle lift which can fulfil its function without being fixed to the floor and may be designed to be transportable 3.6 mobile vehicle lift movable vehicle lift equipped with wheels, rollers, etc. such that it can be moved from one place to another with or without load 3.6.1 manually mobile vehicle lift mobile vehicle lift which is moved by manual effort alone 3.6.2 vehicle lift with powered mobility mobile vehicle lift which is not moved by manual effort 3.7 initial position lower limit position of the carrying device SIST EN 1493:2010

5 Safety requirements and/or measures 5.1 General 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 (all parts) for relevant but not significant hazards, which are not dealt with by this document. 5.2 Preventing unauthorised operation Vehicle lifts shall be equipped with an accessible and fixed device that prevents unauthorized use after taking the lift out of operation (refer to Annex B (informative)). 5.3 Control devices 5.3.1 Hold-to-run control Control devices shall be of the hold-to-run type and shall fulfil the conditions of performance level c of EN ISO 13849-1:2008. The stop-function shall comply with category 0 of 9.2.2 of EN 60204-1:2006. 5.3.2 Grouped control devices If the control devices for more than one vehicle lift are grouped together in one position each control device shall be clearly marked to show which vehicle lift it controls. 5.3.3 Logical operation The control devices shall be designed so that the movement of the control and its location are consistent with its effect (refer to Annex B (informative)). 5.3.4 Marking The direction of the movement of the lifting element shall be permanently marked (refer to Annex B (informative)). The marks shall be suitable symbols or text and can be located on the control devices themselves or directly adjacent to them. 5.3.5 Inadvertent operation Control devices shall be protected from unintentional operation (refer to Annex B (informative)). SIST EN 1493:2010

NOTE This needs negotiation between user and manufacturer respectively supplier of the vehicle lift. In addition if the vehicle lift is mobile the operator shall be able to observe the space especially in moving direction of the vehicle lift. 5.4.3 Controlling several load carrying devices If the load carrying devices of a vehicle lift are intended to be moved independently, a selection control shall be provided that enables: a) the independent movement of each load carrying device; and b) movements of all load carrying devices together. Other combinations of movements of the load carrying devices may also be incorporated and selected by the selection control. The non-selected load carrying devices shall be prevented from operating. 5.4.4 Emergency stop device At a column lift for rail-bound vehicles, each column shall be equipped with an emergency stopping device which fulfils the requirements of EN ISO 13850:2008 and stops the movements of all columns. The emergency stop device shall comply with performance level d of EN ISO 13849-1:2008. The main switch can act as an emergency stop (refer to 5.3.3 and 10.7.4 of EN 60204-1:2006). SIST EN 1493:2010

5.6.2 Tilting speed The speed of tilting, measured at the part of the load carrying device which is furthest away from the turning centre, shall not exceed 0,1 m/s. 5.7 Structural design of the supporting structure 5.7.1 General The design of vehicle lifts in relation to materials, construction and equipment shall be such that a satisfactory level of safety is achieved under all operating conditions including the failure situations described in this standard. This shall be demonstrated by calculation. Use of the permissible stress method is allowable. The stress, resulting from the most unfavourable load distribution, shall be calculated for each load bearing part. For permissible stresses refer to Annex A (informative). The values of Annex A are given under the condition of 22 000 load cycles at rated load. If this value is exceeded, fatigue calculation shall be performed for structure and mechanism. In case of exceptional situation the yield stress divided by a safety factor of 1,1 is acceptable. Wheel support vehicle lifts for road vehicles shall be designed in such a way that during normal operation the maximum inclination of the platform in its longitudinal axes is limited to 1°.
5.7.2 Loads and forces 5.7.2.1 Regular loads a) Structural loads The masses of components of the vehicle lift produce the structural loads. 1) Loads due to components which are not moving are considered to be static structural loads. 2) Loads due to moving components are considered to be dynamic structural loads. b) Rated load SIST EN 1493:2010

5.7.2.3 Exceptional loads a) Out-of-service wind If the vehicle lift is designed for outside use the influence of wind forces in the wheel base direction shall be included in the stress calculation (see also 5.7.3). The maximum pressure of out-of-service wind is 500 N/m2, which is related to a wind speed of 28 m/s. The wind forces acting on the normative vehicle (refer to Table 4) shall be derived from Table 2. It is assumed that in any case the operator lowers the raised vehicle in the nearest position to the ground level at the end of his working time. A corresponding requirement shall be written in the operation instructions if the vehicle lift is designed for outside use. For the overturning stability calculation a stabilising weight effect of 1 kN for each square metre of exposed vehicle surface to the wind can be considered as stabilising moment (refer to Table 2). b) Action 1) of the catching device; or 2) of the re-raising prevention device. c) Test load for: 1) dynamic test (see 6.1.5.2); 2) static test (see 6.1.5.3).
