European foreword
This document (prEN 1493:2024) 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 1493:2023.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
Compared to EN 1493:2010, the following changes have been made:
• The Terms and Definitions chapter (and consequently the entire text of the standard) has been
completely revised
• The presence of people on the raised vehicle is admitted but only in special cases
• References for motorcycles and light quadricycles were added
• Resolved the inconsistency on the interpretation of the normative vehicle in the case of chassis
supporting lifts with arms
• Control devices: completely revised, dividing the controls into two categories: Fixed controls and
mobile controls
• For multiple element lifts (e.g. mobile columns) the “rated load”, intended as the maximum weight
of the vehicle to be lifted, is replaced by the “lifting capacity” referred to the single column
• In the case of special vehicles lifts, two distinct rated loads can be provided: One for normal vehicles
(and therefore based on the Normative Vehicle) and the other specific for the special vehicles for
which the vehicle lift is intended
• Rope calculation: completely revised, with reference to ISO16625: 2013 and ISO 4301-1: 2016
standards
• Vehicle stop devices in wheel support lifts: revised calculation and verification method
• Arm locking devices: revised calculation and verification method. Added prescriptions for anti-slip
safety and play limitation between the various elements of the arms
• Important interventions on the instruction manual requirements
Introduction
This document is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
The object of this document is to define rules for safeguarding persons against the risk of accidents
associated with the operation of vehicle lifts.
While devising this document it was assumed that only authorized persons operate or use the vehicle lifts
and that the working area is sufficiently lit.
This standard assumes that an operator will lower a raised vehicle to the ground level or as low as
possible when he/she is not working on it.
The requirement concerning loading control is not deemed pertinent to this standard in so far 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 vehicle lift is substantially lower than the
maximum.
1 Scope
This document is applicable to vehicle lifts designed to raise vehicles for the purpose of examining and
working on or under the vehicles whilst in a raised position.
Vehicle lifts are not intended to lift persons, but in case of particular use like lift for vehicles periodical
technical inspection or lifts for railbound vehicles, it is allowed for a person to enter a lifted vehicle,
provided that adequate safety measures are defined by the manufacturer and highlighted in the
instruction manual.
The vehicle lift may consist of one or more lifting units, stationary or mobile.
The floor or ground supporting the vehicle lift in use is assumed to be horizontal (tolerance should be
indicated).
This document does not apply to:
o Vehicle lifts designed to lift the vehicle partially
o Vehicle lifts movable when loaded
o Vehicle lifts where the load carrying device can be tilted
o Vehicle lifts where power supply is given by internal combustion engines
o Equipment for power driven parking of motor vehicles (see EN1410:2003 +A1:2009)
Noise is not considered in this document because in practice it does not play a role in vehicle lifts.
This document is applicable to vehicle lifts which are manufactured six months after the date of its
publication as a European Standard.
