Kranai. Sauga. Kranai su rankine pavara

This document specifies requirements for the following hand powered cranes defined in Clause 3: - hand chain blocks; - lever hoists; - jaw winches; - hand powered trolleys supporting lifting machines; NOTE Hand powered trolleys placed on the market on their own and intended to be used with products within the scope of this document are considered as interchangeable equipment as defined in Directive 2006/42/EC. - drum winches; - pulley blocks. This document deals with the following significant hazards, hazardous situations or hazardous events relevant to hand powered cranes, when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer: - mechanical hazards; - thermal hazards; - material/substance hazards; - ergonomic hazards; - hazards associated with the environment in which they are used. This document does not cover hazards related to the lifting of persons. This document is not applicable to hand powered cranes for: - use in ambient temperature outside the range of - 10°C to + 50°C, however for some lifting medium the minimum temperature will be higher than −10 °C; - use in direct contact with food stuffs or pharmaceuticals requiring a high level of cleanliness for hygiene reasons; - handling specific hazardous materials (e.g. explosives, hot molten masses, radiating materials); - operation in an explosive atmosphere. This document is not applicable to hand powered cranes manufactured before the date of its publication.

Kranų sauga. Bendrasis projektavimas. 2 dalis. Apkrovos poveikiai

This document specifies load actions and load combinations for the calculation of load effects as basis for the proof of competence of a crane and its main components. It will be used together with the other generic parts of the EN 13001 series of standards, see Annex E. As such they specify conditions and requirements on design to prevent mechanical hazards of cranes and provide a method of verification of those requirements. NOTE Specific requirements for particular types of crane are given in the appropriate European product standards for the particular crane type, see Annex E. The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and reasonably foreseeable misuse. Clause 4 of this document provides means to reduce or eliminate the risks of mechanical failures due to the following: a) rigid body instability of the crane or its parts (tilting); b) exceeding the limits of strength (yield, ultimate, fatigue); c) elastic instability of the crane or its parts or components (buckling, bulging). The hazards covered by this document are identified by Annex G. This document is not applicable to cranes that are manufactured before the date of its publication as EN.

Kranai. Lengvųjų kranų sistemos

This document applies to: — light crane systems, either suspended or free-standing systems, where the rated capacity of any single hoist mechanism is 4 t or less; — pillar- and wall-mounted jib cranes, without an operator's cabin, whose rated capacity is 10 t or less and whose overturning load moment is 500 kNm or less. NOTE 1 For illustration of crane types, see Annex C. This document is not applicable to cranes covered by another product specific crane standard, e.g. EN 15011:2020 or EN 14985:2012, see Annex E. This document is applicable to cranes and crane systems, whose structures are made of steel or aluminium, excluding aluminium structures containing welded joints. This document gives requirements for all significant hazards, hazardous situations and events relevant to cranes, when used as intended, foreseeable misuse and under foreseen conditions (see Annex A). NOTE 2 Automated operation can be subject to additional requirements. Guidance is given in Annex F. The specific hazards due to potentially explosive atmospheres, ionizing radiation, operation in electro-magnetic fields beyond the range of EN IEC 61000-6-2:2019 and operation in pharmacy or food industry are not covered by this document. This document does not cover hazards related to the lifting of persons. This document is not applicable to cranes manufactured before the date of its publication.
