Safety rules for the construction and installation of lifts - Lifts for the transport of goods only - Part 31: Accessible goods only lifts
|Publication Date:||1 April 2010|
|ICS Code (Lifts. Escalators):||91.140.90|
This European Standard applies to new electric accessible goods only lifts with traction or positive drive and new hydraulic accessible goods only lifts, permanently installed in restricted areas and/or only used by authorised and instructed persons (users), serving fixed and permanent landing levels, having a load carrying unit made of a single load carrying area, designed for the transportation of goods only, moving along a fixed path (e.g. scissor lifts, lifts with guide rails) and inclined not more than 15° to the vertical, with rated speed not exceeding 1 m/s.
This European Standard covers accessible goods only lifts with rated load exceeding 300 kg and not intended to move persons.
This standard deals with all significant hazards, hazardous situations and events with the exception of those listed in 1.3 below, relevant to accessible goods only lifts, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4).
For the purpose of this European Standard, a goods only lift is regarded as accessible where one of the following conditions is satisfied:
a) floor area of the load carrying unit is greater than 1,0 m2;
b) depth of the load carrying unit is greater than 1,0 m;
c) height of the load carrying unit is greater than 1,20 m.
In case of a platform, it is considered accessible when the height of the landing doors is more than 1,20 m.
Two types of accessible goods only lifts are addressed:
a) Type A, where the intended use is bound to the following two simultaneous conditions:
1) maximum rated speed: 0,30 m/s;
2) maximum travelling height: 12 m;
b) Type B, where one of the conditions mentioned above is not fulfilled.
This European Standard does not give the requirements to be met in special cases (potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.).
This standard is not applicable to:
a) accessible goods only lifts:
1) with more than one machine;
2) where loading and unloading is automated or the load carrying unit 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.);
b) lifting appliances, such as appliances with more than one load carrying unit, skips, goods only lifts for construction sites, for underground applications, mine winding gear, goods only lifts on seagoing vessels and mobile offshore units, machinery intended to move performers during artistic performances, 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;
c) installations where the inclination of the fixed course of movement to the vertical exceeds 15°;
d) safety during transport, installation, 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 load carrying unit and for the landing doors with the exception of their vision panels;
f) the use of programmable electronic systems in safety related applications for lifts (PESSRAL).
However, this European Standard may usefully be taken as guidance where relevant.
This European Standard is not applicable to accessible goods only lifts which were manufactured before the date of its publication as EN.
The significant hazards, hazardous situations and events dealt with by this standard are those listed in EN ISO 14121-1:2007, Annex A (see Clause 4) with the exception of:
- any form of radiation except EMC.
