1.3. Essential safety requirements (ESR)
1.3.1 The dump body is constructed in compliance with the "Machinery
Directive" 2006/42/EC and subsequent amendments
.
1.3.2 The equipment complies with the following Italian standards: UNI 10691,
UNI 10692, UNI 10693, UNI 10694, UNI 10695, which regulate the risk
analysis of the dump truck and determine the relative ESR.
1.3.3 Construction criteria
▪
The members of the load-bearing structure are designed in
accordance with the rules of calculation issued by the Motorizzazione
Civile Italiana (Italian vehicles authority), to ensure adequate
resistance and safety in relation to the intended Conditions of Use.
▪
The dump body and relative systems are installed on the vehicle in
accordance with best workmanship practices and in strict compliance
with the instructions of the vehicle manufacturer.
▪
The installation does not affect the value of the sound level
detected by EC in the process of approval of the vehicle cab.
▪
The dump body controls, featuring "maintained action" type operation,
are safe, reliable, and designed in accordance with basic logic criteria.
Controls are clearly visible and marked in such a way as to assure
coherent, practical, and safe manoeuvres.
▪
The high pressure fluid pipelines are designed to withstand the
calculated stresses with an ample safety margin in conditions of the
maximum permissible load as specified in the project.
▪
The hydraulic, pneumatic, and electrical systems are fully tested and
checked.
▪
1.3.4 Safety devices
▪
A pressure relief valve incorporated in the directional control valve or
in the power unit serves to safeguard the various elements of the
hydraulic system from excess stress caused by overpressure.
▪
A 175 A electrical fuse protects the electrical system of the power unit.
▪
A stroke limiting device determines the maximum tipping angle of the
body.
▪
In the standard version the tailgate is released automatically when the
body starts tipping; the latch engages only with the body in its rest
position.
▪
These structures are equipped with removable journals that link the
pivots of the tipping movement and determine rear or side lifting of the
