shall be withdrawn at the latest by January 2010.
This document includes Amendment 1, approved by CEN on 2009-06-19.
This document supersedes EN 1756-2:2004.
The start and finish of text introduced or altered by amendment is indicated in the text by tags ! ".
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 Annexes ZA and ZB, which are integral parts
of this document."
This standard comprises two parts:
Part 1 relates specifically to tail lifts for goods (whether or not accompanied by an operator);
Part 2 covers the special requirements of tail lifts for passengers, including those with disabilities.
This document includes a Bibliography.
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,

Introduction
The machinery concerned and the extent to which hazards are covered are indicated in the scope of
this standard.
While producing this standard, it was assumed that:
 only trained persons operate the machine;
 components without specific requirements are:
a) designed in accordance with the usual engineering practice and calculation codes, including all
failure modes;
b) of sound mechanical and electrical construction;
c) made of materials, with adequate strength and of suitable quality;
d) free of defects;
 harmful materials, such as asbestos are not used;
 components are kept in good repair and working order, so that the required dimensions remain
fulfilled despite wear;
 by design of the load bearing elements, a safe operation of the machine is assured for loading
ranging from zero to 100 % of the rated possibilities and during the tests;
 a mechanical device built according to good practice and the requirements of the standard, will
not deteriorate to a point of creating a hazard without the possibility of detection;

 the equipment is capable of operating correctly within a temperature range of – 15 °C to + 40 °C;
 a negotiation takes place between the manufacturer of the tail lift and the installer for the
characteristics of the supporting wheeled vehicle (see also clause 6), the fitting of the tail lift on or
in the vehicle and between the installer and the user relating to the specific conditions of the use,
places of use of the machinery, also some of the characteristics of the vehicle and the
appropriate language;
 the working area is adequately lit (if lighting is not provided with the tail lift);
 if the place of installations allows a vertical falling height of persons of more than 3 m
notwithstanding the limited travel height indicated in the scope, means external to the machine
are used to limit this falling height to 3 m.
!This European Standard is a type C standard as stated in EN ISO 12100."
When the 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 built according to the provisions of this type C standard.
1 Scope
Part 2 of standard EN 1756 specifies safety requirements for design of tail lifts as defined in 3.1 for
mounting on wheeled passenger vehicles.
Vehicles for the loading of disabled passengers onto aircraft and ships are included within the scope
of the standard (although dock-mounted lifts are excluded).
It also specifies the verification of such tail lifts and the safety information that shall be provided for
their use.
This document deals with the technical requirements to minimise the hazards listed in clause 4 which
can arise during the operation of tail lifts when carried out in accordance with the specifications as
intended by the manufacturer or his authorised representative.
It applies to passenger tail lifts:
 used for the purpose of embarking and/or disembarking passengers to and from such vehicles;
 intended to be fitted, temporarily or permanently, either inside or on the front, side or rear of the
wheeled vehicle;
 driven either by hand or by electric power;
 equipped with a platform to support passengers who may be pedestrians or riders in wheelchairs
and may be accompanied by an attendant.
Embarking and/or disembarking operations include the use of a tail lift to lift and/or lower passengers,
and if specifically approved by the manufacturer, for use as a link bridge.
The standard covers the significant hazards which could occur when a tail lift is used as intended and
under the conditions foreseen by the manufacturer. A list of significant hazards is given in clause 4.
This document is not applicable to tail lifts which are manufactured before the date of publication of
this document by CEN.

5 Safety requirements and/or measures
5.1 General requirements
Except where otherwise specified in the text, tail lifts shall generally comply with the provisions of:
 EN 811 for safety distances;
 EN 982 for hydraulic equipment.
Machinery shall comply with the safety requirements and/or measures of this clause and in attention
with EN ISO 12100-1 and EN ISO 12100-2 for hazards relevant but not significant which are not dealt
with in this standard.
5.1.1 Sizes and capacities of tail lifts
The requirements for maximum load and platform size depend on the category of vehicle on which the
tail lift is intended to be used. Capacities and platform sizes shall conform to the figures stated in
Table 1B.
