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);

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.

Mobile elevating work platforms - Part 2: Additional safety requirements for load lifting appliances on the extending lifting structure and work platform
EN 280-2:2022

This document, which shall be used in conjunction with EN 280-1:– , 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.

This standard deals with power operated temporarily installed builders hoists intended for use by persons who are permitted to enter sites of engineering and construction, serving either one upper landing or a work area extending to the end of the guides, (e.g. a roof) having a load carrying device (lcd): - which is intended for the transportation of goods only; - where it is forbidden for persons to step upon it at any time; - which is guided; - which is designed to travel at an angle of at least 30 degrees to the vertical but may be used at any angle between the vertical and the maximum inclination as specified by the manufacturer; - which is sustained by steel wire rope and a positive drive system; - which is controlled by hold-to-run controls by the operator; - which does not benefit from the use of any counterweight; - which has a maximum rated load of 300 kg; - which has a maximum speed of 1,00 m/s; and where the guides require support from separate structures. The standard 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. The safety requirements and/or measures of this standard deal with the design of the base frame, guide rails, lcd, drive unit, electrical and/or hydraulic installation and the control of the hoist. Included is the design of any guide rail support but not the design of the supporting structure (e.g. building or scaffold) and any ties. Other aspects such as base enclosure, the design of any concrete, hard core, timber or other foundation arrangement, hoistway protection and the upper landing are dealt with in the users' manual section of this standard.
