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 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.
