This document, which shall be used in conjunction with EN 280-1:–1, specifies the additional safety requirements for MEWPs of Type 1 equipped with a load lifting appliance. The load lifting appliance is designed for lifting suspended loads directly in support of the task being carried out by personal from the work platform. This European Standard deals with the significant hazards, hazardous situations and events relevant to the lifting of loads outside the scope of EN 280-1:–1), when the MEWP and load lifting appliance are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer of the MEWP. The significant hazards covered by this standard are listed in Clause 4.

This European Standard does not cover the following:

a) the use of a MEWP for lifting persons as a suspended load;

b) the use of a MEWP for lifting suspended loads from a control position other than the work platform;

NOTE Where a control position other than the work platform is used the relevant crane standards (e.g. EN 13000, EN 12999) apply.

c) requirements for lifting accessories;

d) raising or lowering of suspended loads for general materials handling as carried out by a crane.

Load lifting devices can be:

a) fixed load attachment points on the work platform or on the extending lifting structure;

b) lifting equipment for raising or lowering the load with a stationary platform. The equipment is attached to the work platform or extending structure and may have a jib.

NOTE The lifting equipment can be either permanently attached or interchangeable.

1.1 This document specifies safety requirements and measures for all types and sizes of Mobile Elevating Work Platform (MEWP, see 3.1) intended to move persons to working positions where they are carrying out work from the work platform (WP) with the intention that persons are getting on and off the work platform only at access positions at ground level or on the chassis. This document also covers static elevating work platforms of group B (see 1.4). NOTE Machines designed for the handling of goods which are equipped with work platforms as interchangeable equipment are regarded as MEWPs. 1.2 This document is applicable to the structural design calculations and stability criteria, construction, safety examinations and tests before MEWPs are first put into service. It identifies the hazards arising from the use of MEWPs and describes methods for the elimination or reduction of these hazards. It does not cover the hazards arising from: a) use in potentially explosive atmospheres; b) electromagnetic incompatibility; c) work from the platform on external live electric systems; d) use of compressed gases for load bearing components; e) getting on and off the work platform at changing levels; f) specific applications (e.g. railway, ships) covered by National or local regulations. 1.3 This document does not apply to: a) machinery serving fixed landings (see e.g. EN 81-1 and EN 81-2, EN 12159); b) fire-fighting and fire rescue appliances (see e.g. EN 1777); c) unguided work cages suspended from lifting appliances (see e.g. EN 1808); d) elevating operator position on rail dependent storage and retrieval equipment (see EN 528); e) tail lifts (see EN 1756-1 and EN 1756-2); f) mast climbing work platforms (see EN 1495); g) fairground equipment; h) lifting tables (see EN 1570-1 and EN 1570-2); i) aircraft ground support equipment (see e.g. EN 1915-1 and EN 1915-2); j) elevating operator positions on industrial trucks (see EN 1726-2). 1.4 Classification: MEWPs are divided into two main groups: a) Group A: MEWPs where the vertical projection of the centre of the area of the platform in all platform configurations at the maximum chassis inclination specified by the manufacturer is always inside the tipping lines. b) Group B: All other MEWPs. Relating to travelling, MEWPs are divided into three types: 1) Type 1: Travelling is only allowed with the MEWP in its transport configuration; 2) Type 2: Travelling with raised work platform is controlled from a point of control at the chassis; 3) Type 3: Travelling with raised work platform is controlled from a point of control at the work platform. NOTE Type 2 and type 3 can be combined.

This document applies to light offshore cranes including their supporting pedestals and structures.

NOTE The supporting pedestal and structures such as columns and boom rests are covered by this standard to the extent where their main purpose is to support the crane.

This document is applicable to light offshore cranes, whose structures are made of steel.

The following characteristics distinguish light offshore cranes from other types of offshore cranes:

— maximum rated capacity 20 tonnes, maximum load moment 300 tm;

— limitation for off-board lifting operation Hs = 2,0 m and wind speed 15 m/s (3s gust);

— maximum number of working cycles class U3 (C ≤ 1,25 × 105) according to EN 13001-1.

This document gives requirements for all significant hazards, hazardous situations and events relevant to light offshore cranes, when used as intended and under conditions foreseen by the risk assessment (see Clause 4).

This document is not applicable for:

a) transportation, assembly, disabling, scrapping or changing the configuration of the crane;

b) non-fixed load lifting attachments, i.e. any item between the hook and the load;

c) lifting operations in ambient temperatures below −20 °C;

d) lifting operations in ambient temperatures above 45 °C;

e) lifting operations involving more than one crane;

f) accidental loads due to collisions or earthquakes;

g) emergency personnel rescue operations (except training);

h) subsea lifting operations;

i) general purpose offshore cranes, floating cranes and motion compensated cranes.

This document is applicable for the lifting of personnel.

This document is applicable to light offshore cranes, which are manufactured after the date of approval by CEN of this document.
