Earth-moving machinery - Safety - Part 6: Requirements for dumpers
This part of prEN 474 deals with all significant hazards, hazardous situations and events relevant to wheel and crawler dumpers as defined in EN ISO 6165:2002, 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 formulated in part 1.
This part does not repeat the requirements from part 1, 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, hazardous situations and events during commissioning, operation and maintenance of dumpers.
Pedestrian controlled dumpers are excluded from scope of this European Standard.
This European Standard is not applicable to dumpers, manufactured before the date of publication of this European Standard by CEN.

5 Requirements and/or measures
5.1 General
Dumpers shall comply with the requirements of EN 474-1:2006, as far as not modified or replaced by the
requirements of this part.
5.2 Dump body
5.2.1 Control device
When the content of the body 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 operator's 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 position (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 visible 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,
maintenance 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

NOTE A solution is to provide an exhaust heating system for the dump body.
Compact dumpers are excluded from this requirement.
5.3 Retarder
Dumpers, except compact dumpers and crawler dumpers, shall be equipped with a retarder system, which
meets the requirements of ISO 10268:1993.
5.4 Articulated frame lock
EN 474-1:2006, 5.14.5 applies with the following exceptions:
The articulated frame lock device shall meet the requirements in ISO 10570:2004 except that the requirement
for articulated dumpers is limited to a steering torque (expressed in Newton per metre) of 4,0 times the
steering torque for the unloaded machine.
This articulated frame lock device shall be tested to withstand a force of 1,2 times or more
