Foreword
This document (CEN/TS 13778:2004) has been prepared by Technical Committee CEN/TC 151
“Construction equipment and building material machines — Safety”, the secretariat of which is held by
DIN.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus,
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Introduction
This document is equivalent to a Type C-standard as stated in EN 1070.
The machinery concerned and the extent to which hazards are covered are indicated in the scope of
this document.
Those hazards that are relevant for all mechanical, electrical, hydraulic, pneumatic and other
equipment of machinery and that are dealt with in standards for common use are not covered by this
document. Reference to pertinent standards of this kind is made where such standards are applicable
and so far as is necessary.
1 Scope
This document specifies the safety requirements for mobile demolition machinery that is designed for
demolishing by pushing or pulling, or fragmenting by crushing or shearing, buildings and/or other civil
engineering structures and their component parts and/or separating the resultant debris.
NOTE 1 Demolition machines can also be used for separating and sorting the resultant debris, but this is not
their primary purpose.
NOTE 2 Where demolition machines are used on public roads, the national traffic regulations apply.
Mobile demolition machinery can be an earth-moving machine (see EN 474-1:1994, -3:1996, -4:1996,
–5:1996 and prEN 474-12:1998) equipped with special equipment and attachments for demolition
work, for example, ball, breaker, crusher, hydraulic or free-fall hammers, jaws. Mobile demolition
machinery may be controlled either by a ride-on operator or by a remote control system (see Figure 1).
Machines for specific applications, for example, road surface breaking machines and remotely
controlled demolition machines are also included in this document.
This document deals with all significant hazards pertinent to mobile demolition machinery (see Clause
4), when they are used as intended and under the conditions foreseen by the manufacturer. This
document specifies the appropriate technical measures to eliminate or reduce risks arising from the
significant hazards.
The base machine can have the same safety requirements as other types of mobile construction
machinery and these will therefore comply with the requirements of the European and International
standards written for other machines (see normative references).
This document includes those requirements which are necessary for mobile machinery only when
they are designed to be used in the demolition process.
This document applies primarily to the machines which are manufactured after the date of approval of
the standard by CEN.
NOTE 3 Directive 94/9/EC concerning equipment and protective systems intended for use in potentially
explosive atmospheres can be applicable to the type of machine or equipment covered by this document. The
present standard is not intended to provide means of complying with the essential health and safety requirements
of Directive 94/9/EC.

conditions as specified in 4.9 of EN 474-3:1996, 4.1.7 of EN 474-3:1996 and 4.10 of EN 474-4:1996).
Device(s) intended to increase the stability of mobile demolition machinery in working mode (for
example, outriggers, oscillating axle locking) shall be fitted with locking devices which keep them in
position.
NOTE Special stability requirements are not needed for road surface breakers due to their design and
method of use.
