Safety rules for the construction and installation of lifts - Lifts for the transport of goods only - Part 31: Accessible goods only lifts
1.1 This document specifies the safety rules for new accessible goods only lifts with traction, positive or hydraulic drive, permanently installed and only used by instructed persons (users), serving fixed and permanent landing levels, having a carrier made of a single load carrying area, designed for the transportation of goods only, moving along a fixed path by rigid guide rails and inclined not more than 15° to the vertical, with rated speed not exceeding 1 m/s.
This document covers accessible goods only lifts with rated load exceeding 300 kg and not intended to transport persons, on account of controls not operable from inside the carrier.
1.2 For the purpose of this document, a goods only lift carrier is regarded as accessible where one of the following conditions is satisfied:
a) floor area of the carrier is greater than 1,0 m2;
b) depth of the carrier is greater than 1,0 m;
c) clear height of the carrier is greater than 1,20 m.
In case the carrier is a platform, it is considered accessible when the clear height of the landing doors is greater than 1,20 m.
1.3 Two types of accessible goods only lifts are addressed:
a) Type A, where the intended use is bound to the maximum rated speed of 0,30 m/s;
b) Type B, where the intended use is bound to the maximum rated speed of 1,0 m/s.
1.4 In addition to the requirements of this document, supplementary requirements have to be considered in special cases (potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.).
1.5 This document does not cover:
a) accessible goods only lifts:
1) with more than one lift machine;
2) where loading and unloading is automated, or the carrier floor is fitted with mobile devices (e.g. rollers) for loading and unloading purposes;
3) intended to carry bulk loads (such as loose sand, gravel, etc.);
4) with drive systems other than those stated in 4.8;
b) lifting tables according to EN 1570-1 and EN 1570-2;
c) lifting appliances, such as appliances with more than one carrier, skips, goods only lifts for construction sites, for underground applications, mine winding gear, goods only lifts on seagoing vessels and mobile offshore units, construction and maintenance appliances in wind turbines, goods only lifts specially designed and constructed for research purposes for temporary use in laboratories, goods only lifts specially designed and constructed for military or police purposes;
d) safety during operation of transport, erection, repairs and dismantling of accessible goods only lifts;
e) the use of translucent material for the walls of the well and machinery spaces, for the carrier with the exception of the landing doors vision panels;
f) the use of programmable electronic systems in safety related applications for lifts (PESSRAL);
g) important modifications (see Annex D) to an accessible goods only lifts installed before this document is brought into application;
h) hydraulic lifts where the setting of the pressure relief valve exceeds 50 MPa (see 4.8.3.5.3);
i) any form of radiation except EMC;
j) fire propagation;
k) energy dissipation type buffers.
However, this document can usefully be taken as a basis.
Noise and vibrations are not dealt with in this document as they are not considered a significant nor relevant hazard for the actual type of the accessible goods only lifts (see also 0.4.1).
1.6 This document is not applicable to accessible goods only lifts which were manufactured before the date of its publication as EN.

This document (prEN 81-31:2022) has been prepared by Technical Committee CEN/TC 10 “Lifts,
escalators and moving walks”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 81-31:2010.
This document is part of the EN 81 series of standards “Safety rules for the construction and installation
of lifts”. This is the second edition.
The main changes with respect to the previous edition (EN 81-31:2010) are listed below:
— Requirements have been updated, taking into account EN 81-20:2020, EN 81-50:2020 and
EN 81-21:2009+A1:2012. Specifically: definitions; strength of the doors, screens, partitions;
unintended carrier movement; refuge spaces; inspection operation; rope's retainers; balustrade;
lighting.
— The scope has been amended. Specifically: excluded overlapping with EN 1570, by use of rigid guide
rails only; excluded scissor lifts; removed travel limit for Type A; non-addressed energy dissipation
type buffers.
— Requirements and verifications have been added for: refuge spaces; clamping devices; pawl devices;
automatic power operated doors; progressive safety gears.
— Improvements in safety due to changes in proven technology and in the state of the art have been
made. Specifically: working spaces; electrical equipment; emergency electrical operation;

linear characteristics; alarm system.
— The reported errors have been eliminated. Specifically: hydraulic formulae;
— The text has been clarified. Specifically: pulley room; extreme position of the carrier in the well; use
in limited / not limited access area; ingress in / egress from the well;
— The references to other standards have been updated, according to the progress in that field. All
standards now include a date;
— Wording has been amended. Specifically: from “uncontrolled movement” to “unintended movement”;
from “manual operation” to “emergency operation”; from “safety space” to “refuge space”; from “load
carrying unit” to “carrier”; from “vendor” to “manufacturer”; from “laboratory” to “examiner”;
— The informative Annex “List of significant hazards” has been added;
— The informative Annex “Building interface” has been added;
— Annex ZA has been updated with regard to the European Commission mandate M/396.

Introduction
0.1 General
This document is a type-C standard as stated in EN ISO 12100:2010.
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 in the drafting
process of this document.
The accessible goods only lift installation concerned and the extent to which hazards, hazardous
situations and events are covered are indicated in the scope of this document.
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.
0.2 General provision
0.2.1 The object of this document is to define safety rules related to the construction and installation of
