Self-loading mobile concrete mixers - Safety requirements and verification
This document specifies general safety requirements for self-loading mobile concrete mixers (here-after referred to as “SLMs”) as defined in ISO 18650-1:2021, with rigid or articulated wheeled chassis.
This document applies to SLMs which are designed for front or rear loading and can be provided with a slewing and/or tilting frame where the rotating drum and the self-loading equipment (lift arms and bucket) are mounted on. SLMs can also be fitted with accessories such as water dosing means and a weighing system.
This document is not applicable to the following:
- machines designed primarily for earth moving, such as loaders or dumpers (see applicable parts of the EN 474 series);
- truck mixers (see EN 12609).
This document deals with all significant hazards, hazardous situations and events relevant to SLMs, whether used as intended and under conditions foreseen or under conditions of misuse reasonably foreseeable by the manufacturer (see Annex A).
This document does not address hazards that can occur:
- during manufacture;
- when using SLMs on public roads, where specific local road regulations can apply;
- when operating in potentially explosive atmospheres.
This document does not address hazards specifically related to:
- SLMs designed to operate with varying levels of autonomy or when SLMs have embedded safety-systems with fully or partially self-evolving behaviour or logic using machine learning approaches, including collaborative applications;
- SLMs when intended to be connected to the internet or to an external network or device that communicates with it.
This document is not applicable to SLMs manufactured before the date of its publication.

Introduction
This document is a type-C standard as stated in EN ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in the case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
1 Scope

EN 474 series);
— truck mixers (see EN 12609).
This document deals with all significant hazards, hazardous situations and events relevant to SLMs,
whether used as intended and under conditions foreseen or under conditions of misuse reasonably
foreseeable by the manufacturer (see Annex A).
This document does not address hazards that can occur:
— during manufacture;
— when using SLMs on public roads, where specific local road regulations can apply;
— when operating in potentially explosive atmospheres.
This document does not address hazards specifically related to:

systems with fully or partially self-evolving behaviour or logic using machine learning approaches,
including collaborative applications;
— SLMs when intended to be connected to the internet or to an external network or device that
communicates with it.
This document is not applicable to SLMs manufactured before the date of its publication.

read in darkness.
4.3.3 Operator-protective structures
4.3.3.1 General
Operator-protective structures shall conform to 4.3.3.2 and 4.3.3.3, except that structural members of the
falling-object protective structure (FOPS) and the roll-over protective structure (ROPS) and the mounts
which attach them to the SLM frame when made from steel shall have one of the following Charpy V- notch
impact strengths (see ISO 148-1 and ISO 148-2):
10 mm × 10 mm specimen: 11 J at −10 °C
10 mm × 7,5 mm specimen: 9,5 J at −10 °C
10 mm × 5 mm specimen: 7,5 J at −10 °C
10 mm × 2,5 mm specimen: 5,5 J at −10 °C
4.3.3.2 Roll-over protective structure (ROPS)
SLMs shall be equipped with a roll-over protective structure (ROPS). The ROPS shall conform to
EN ISO 3471:2008. Table 1 shall be applied to determine the values to be met when testing the ROPS.

4.3.3.3 Falling-object protective structure (FOPS)
SLMs shall be equipped with a falling-object protective structure (FOPS). The fitted FOPS shall be in
accordance with level I of EN ISO 3449:2008.
4.4 Operator’s seat
4.4.1 General requirements
SLMs shall be fitted with an adjustable seat that supports the operator in a position that allows the operator
to control the SLM under the intended operating conditions.
4.4.2 Dimensions
The seat dimensions shall be in accordance with ISO 11112:1995.
4.4.3 Adjustment
All adjustments to accommodate the operator’s size shall conform to ISO 11112:1995 with the exception
that the fore and aft adjustment may be reduced to ± 35 mm and the vertical adjustment is not required.
Adjustments shall be possible without the use of any tool.
4.4.4 Vibration
Operator’s seats shall meet the requirements of input spectral class EM1 or EM7 according to
EN ISO 7096:2020 with regard to its ability to reduce the vibration transmitted to the operator.
NOTE Tests have shown that class EM1 or EM7 for dumper is also suitable for SLMs since travelling is the most
relevant contribution to the vibration value.
4.4.5 Restraint system
SLMs shall have an operator restraint system in accordance with EN ISO 6683:2008 or ISO 3776-1:2006,
ISO 3776-2:2013 and ISO 3776-3:2009, or equivalent.
Means shall be provided to prevent powered travel movements of the SLM when the operator is at the
driving position, the travelling direction is selected, and the restraint system is not fastened.
A visual and audible signal shall be activated when the operator is at the driving position, the travelling
direction is selected, and the restraint system is not fastened.
4.5 Operator’s controls and indicators
4.5.1 General
The controls (hand levers, joysticks, pedals, switches, etc.) of the SLM shall be chosen, designed,
constructed and arranged in accordance with ISO 10968:2020, so that:
— they shall be accessible in accordance with EN ISO 6682:2008;
— they shall be marked in accordance with ISO 6405-1:2017 and ISO 6405-2:2017;
— the movement of the control devices to activate the functions and indicators shall correspond to the
intended effect or common practice whenever possible;
— the normal engine stop device shall be within the zone of reach as defined by EN ISO 6682:2008;
— when a control such as a keyboard or joystick control is designed and constructed to carry out several
functions, the activated functions shall be clearly identified.

SLMs and its working equipment shall be designed so that movements that can cause a hazard are not
possible, without activating the controls while starting or stopping the engine.
4.5.3 Controls activation
All controls shall return to their neutral position when the operator releases the control. Functions that do
not cause a hazard may have a detent for continuous activation, e.g. water pump activation or drum
rotation.
4.5.4 Inadvertent activation
Controls that can cause a hazard due to inadvertent activation shall be so arranged, deactivated or guarded
as to minimize the risk including while the operator is getting into or out of the operator’s station. The
deactivation device shall either be self-acting or shall act by compulsory actuation of the relevant device.
4.5.5 Pedals
If the pedals of a SLM have the same function (clutch, brake, and accelerator) as on a motor vehicle, they
