Introduction
This document is applicable to rough-terrain variable-reach trucks homologated as tractors according
to 167/2013, called rough-terrain variable-reach tractors (RTVR tractors).
This document is also intended to highlight and explain the requirements of the Machinery Directive
2006/42/EC applicable to the permanently mounted equipment on a RTVR tractor.
It is based on EN 1459-1:2017.
The two following regulations apply to those RTVR tractors with permanently mounted equipment:
Tractor regulation 167/2013
Machinery directive 2006/42/CE for the permanently mounted equipment.
As a consequence, the two following documents accompany each piece of equipment:
— COC certificate of conformity
— DOC declaration of conformity for permanently mounted equipment
The permanently mounted equipment bears the CE marking.
All quantities are in SI units, and this includes metric units.
This document is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous 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
standards, for machines that have been designed and built according to the provisions of this type C
standard.
1 Scope
This document specifies requirements related to permanent mounted equipment for rough-terrain
variable-reach tractors (here-after referred to as “RTVR tractors”) and additional requirements for the
combination.
This document does not apply to:

This document does not address hazards which may occur
a) when handling suspended loads which may swing freely;
b) when using RTVR tractors on public roads;
c) when operating in potentially explosive atmospheres;
d) when operating underground;
e) when towing trailers;
f) when fitted with a personnel work platform (additional requirements are given in EN 1459-3);
g) when using cruise-control.
This document does not provide a method of calculation for fatigue and strength of material.
