CEN/TC 144/WG 5 - Stationary equipment

This document specifies the safety requirements for the design of must and grape harvest pumps and the means for verifying these requirements and gives information for the safe use of the machines covered.
This document applies to must and grape harvest pumps, as defined in 3.1, intended for the transfer of fresh, de-stemmed grapes and pomace.
This document deals with all significant hazards, hazardous situations or hazardous events relevant to grape harvest pumps, when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, specified in Annex B.
This document does not deal with hazardous phenomena associated with the integration of grape harvest pumps with other machinery.
This document does not give additional requirements for operations subject to special rules (e.g. explosive atmosphere, power supply from electrical networks where the voltage, frequency and tolerance differ from those of the public network).
This document is not applicable to:
-   adaptations intended for other fruit harvests;
-   pumps for building materials (covered by EN 12001 [1]);
-   pumps on grape harvesters;
-   reception conquests;
-   machines upstream or downstream of the pump.
This document is not applicable to grape harvest pumps manufactured before the date of its publication.

This European Standard specifies safety requirements for the design and construction of unloaders mounted in stationary round silos for the removal of the silage and similar materials. It applies to electrically powered, slowly rotating unloaders which operate on top surface of the stored silage surface.
It describes methods for the elimination or reduction of hazards for which specific requirements on unloaders, as defined in 3 and shown in Annex B, are necessary. In addition, it specifies the type of information to be provided by the manufacturer on safe working practices.
The document only deals with the hazards generated by the silo unloader and not with those of the silo system itself (e.g. hazards arising from generated gases).
This document is not applicable to noise and fire hazards and hazards related to the foreseeable misuse.
The document does not deal with technical requirements for installation or removal of the unloader from one silo to another.
The list of significant hazards dealt with in this document is given in annex A. Annex A also indicates the hazards which have not been dealt with.
The environmental aspects have not been considered in this document.
This document applies primarily to machines which are manufactured after the date of issue of this document.
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 document is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.
