24、ch hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other sta
25、ndards, for machines that have been designed and built according to the provisions of this type C standard. BS EN 474-6:2006+A1:2009EN 474-6:2006+A1:2009 (E) 7 1 Scope This part of EN 474 deals with all significant hazards, hazardous situations and events relevant to wheel and crawler dumpers as def
26、ined in EN ISO 6165:2006, including compact dumpers, and compact dumpers with standing operator when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). The requirements of this part are complementary to common requirements fo
27、rmulated in !EN 474-1:2006+A1:2009“. This part does not repeat the requirements from !EN 474-1:2006+A1:2009“, but adds or replaces the requirements for application for dumpers. This part specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards, h
28、azardous situations and events during commissioning, operation and maintenance of dumpers. Pedestrian controlled dumpers are excluded from the scope of this European Standard. This European Standard is not applicable to dumpers, manufactured before the date of publication of this European Standard b

NOTE 2 Definitions used in EN and ISO standards referred to in this European Standard are a
35、lso valid for this document. 3.1 dumper self-propelled crawler or wheeled machine, with an open body, which transports and dumps or spreads material (see EN ISO 6165:2006 and Figures B.1 and B.2) NOTE Except for compact dumpers, loading is performed by other machines or equipment. 3.2 rigid frame du
36、mper dumper with a rigid frame and wheel or crawler steering (see EN ISO 6165:2006, Figure B.1and Figure B.3) 3.3 articulated frame dumper dumper with an articulated frame for steering (see EN ISO 6165:2006 and Figure B.2) 3.4 swing dumper dumper having a 360 swing upper structure (see EN ISO 6165:2

BS EN 474-6:2006+A1:2009EN 474-6:2006+A1:2009 (E) 9 5.2 Dump body 5.2.1 Control device When the content of the body
41、 can be dumped manually, the control device shall be designed and placed so that the opening and closing can be actuated safely, e.g. from the operators position or from a side different from the tipping direction. 5.2.2 Body lowering In case of loss of energy, lowering the body to the transport pos
42、ition (frame) shall be possible in a safe way without special tools ,e.g. by a manually operated valve. 5.2.3 Body down indicator Dumpers shall have the following provisions: a device preventing travelling with a speed higher than 10 km/h when the body is not completely lowered; an audible and/or vi
43、sible warning device functioning when the body is not in a lowered position and the transmission is engaged. Compact dumpers are excluded from this requirement. 5.2.4 Body support device A mechanical body support device shall be provided to support the body in lifted position during service, mainten
44、ance and other non-operational purposes. The device shall meet the requirements in ISO 13333:1994. 5.2.5 Sticking load Where there is a risk of loosing stability while dumping due to the load freezing to the body, provisions shall be made to assist discharge of the load.
