-   travelling with a speed not more than 1,0 m/s for permanent lifts and not more than 0,4 m/s for temporary lifts.
1.2   This document identifies hazards as listed in Clause 4 which arise during the various phases in the life of such equipment and describes methods for the elimination or reduction of these hazards when used as intended by the manufacturer.
1.3   This document does not specify the additional requirements for:
-   operation in severe conditions (e.g. extreme climates, strong magnetic fields);-
-   lightning protection;
-   operation subject to special rules (e.g. potentially explosive atmospheres);
NOTE   Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.
-   electromagnetic compatibility (emission, immunity);
-   handling of loads the nature of which could lead to dangerous situations;
-   the use of combustion engines;
-   hydraulic drive units;

Introduction

This document is one of a series of standards produced by CEN/TC 10/SC 1 as part of the CEN programme

of work to produce machinery safety standards.
This document is a Type C standard as stated in EN ISO 12100:2003.

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are

covered are indicated in the scope of this standard.
This document gives details for the complete installation.

In order to achieve a safe installation of a lift on a crane negotiations shall take place between the

manufacturer of the lift and the crane user organisation about the interfaces (e.g. lift way protection,

supporting structure, power supplies, suitability of alarm devices) regarding the responsibility for the supply of

these requirements.

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."

1 Scope

1.1 This document specifies the safety requirements for the construction and installation of power operated

lifts attached to cranes and intended for access to workplaces on cranes, by authorised persons. This includes

intended use, erection, dismantling, inspection and maintenance. The lift serves defined landing levels and

has a load carrying unit which is:
a) designed for the transportation of persons and goods;
b) guided;

c) travelling vertically or along a path within 15 degrees maximum from the vertical;

d) supported by rack and pinion or suspended by steel wire ropes;

e) travelling with a speed not more than 1,0 m/s for permanent lifts and not more than 0,4 m/s for temporary

lifts.

1.2 This document identifies hazards as listed in Clause 4 which arise during the various phases in the life

of such equipment and describes methods for the elimination or reduction of these hazards when used as

intended by the manufacturer.
1.3 This document does not specify the additional requirements for:

a) operation in severe conditions (e.g. extreme climates, strong magnetic fields);

b) lightning protection;
c) operation subject to special rules (e.g. potentially explosive atmospheres);

NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive

atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present

standard is not intended to provide means of complying with the essential health and safety requirements of Directive

94/9/EC.
d) electromagnetic compatibility (emission, immunity);
e) handling of loads the nature of which could lead to dangerous situations;
f) the use of combustion engines;
g) hydraulic drive units;
h) hazards occurring during manufacturing process;
i) hazards occurring as a result of being erected over a public road;
j) earthquakes;

k) noise (see also Directive on noise emissions from machines used outdoors (2000/14/EC)).

1.4 This standard is not applicable to:

a) builders hoists according to EN 12158-1:2000, EN 12158-2:2000 and EN 12159:2000;

---------------------- Page: 8 ----------------------
SIST EN 81-43:2009
EN 81-43:2009 (E)
b) elevating control stations according to EN 14502-2:2005+A1:2008;
c) lifts according to EN 81-1:1998;
d) work platforms carried on the forks of fork trucks;
e) work platforms;
f) funiculars;
g) lifts specially designed for military purposes;
h) mine lifts;
i) theatre elevators.

1.5 This standard deals with the complete lift design but excludes the design of the crane. It includes the

base frame and base enclosure but excludes the design of any concrete, hard core, timber or other foundation

arrangement. It includes the design of mast ties and the design of anchorage parts between the mast tie and

the crane structure. This standard also includes the design of the landing gates and their fixings.

5 Safety requirements and/or protective measures
5.1 General

The design of the lift shall consider intended use, erection, dismantling, inspection and maintenance.

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 12100-1:2003 and

EN ISO 12100-2:2003 for hazards relevant but not significant, which are not dealt with by this document (e.g.

sharp edges)

SIST EN 81-43:2009
EN 81-43:2009 (E)

The design of all components that have to be handled during erection e.g. mast sections, shall have their

weight assessed against manual handling. Where the permissible weight for manual handling is exceeded,

the manufacturer shall give recommendations in the instruction handbook concerning suitable lifting

equipment.
All removable and detachable covers shall be retained by captive fastenings.
5.2 Load combinations and calculations

5.2.1 The structure of the lift shall be designed and constructed in such a way that its strength is satisfactory

under all intended conditions, including erection and dismantling.

The design of the structure of the lift as a whole and each part of it shall be based on the effects of any

possible combination of loads as specified in this Sub-clause 5.2. The load combinations shall consider the

least favourable locations of the car and load relative to the mast and its ties, both during the vertical passage

of the car and any horizontal movement of the car. Ties between the mast and the supporting structure are

considered to be part of the lift structure.

These load combinations are summarised in Table 2 — Load cases and safety factors.

Use of forces, load combinations and formulas in accordance with EN 81-1:1998 is accepted for permanent

installed lifts. Forces and load combinations not covered by EN 81-1:1998 such as mobility, wind forces and

rated load shall be calculated according to this standard.

5.2.2 When calculating the lift structure and every related component, the following forces and loads shall be

taken into account:
5.2.2.1 All dead weights with the exception of the car and equipment
