Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 2867 was prepared by Technical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 2,

Safety, ergonomics and general requirements.

This seventh edition cancels and replaces the sixth edition (ISO 2867:2006), which has been technically

revised.

Introduction
The structure of safety standards in the field of machinery is as follows.

a) Type-A standards (basic standards) give basic concepts, principles for design and general aspects that

can be applied to machinery.

b) Type-B standards (generic safety standards) deal with one safety aspect or one type of safeguard that

can be used across a wide range of machinery:

⎯ type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise);

⎯ type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-sensitive

devices, guards).

c) Type-C standards (machinery safety standards) dealing with detailed safety requirements for a particular

machine or group of machines.
This document is a type-C standard as stated in ISO 12100.

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 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.

NOTE ISO 14122 is a series of type-B standards that provides general requirements for access to stationary and

mobile machines and that can be used as a general reference for the design of access systems for earth-moving

machines.

maintenance point, a system such as one of the following shall be provided (together with corresponding

instructions in the operator's manual if this is not obvious):

⎯ a stairway or ramp to provide access where two-point support is adequate and one hand can be available

for carrying items;

⎯ additional platforms or surfaces, with minimum dimensions of 300 mm by 400 mm every 1,7 m of height

on a continuous climbing access system, where items can be temporarily placed so that three-point

support can be maintained when moving on the access system;

⎯ a procedure or system (e.g. rope pulley system) for transferring items to the operator station or routine

maintenance point so that three-point support can be used on the access system at all times.

NOTE Routine maintenance points serviced from the ground meet these requirements.

4.1.9 Illumination shall be provided for the primary access system to the operator station if the platform of

the operator station is at a height of more than 3 m. Activation of lights shall be possible from the ground and

the operator station.

4.1.10 Access systems shall be fitted for the use and daily maintenance of attachments or options (e.g.

mirrors) provided by the machine manufacturer.

4.1.11 For routine maintenance intervals that exceed one month, other access system aids, such as

personal fall arrest systems (PFASs), personal fall restraint systems (PFRSs), or an external access system

(e.g. portable working platform, stairway) can be used. The operator's manual shall provide guidance for the

use of other access system aids. Anchorage points, if provided, shall be in accordance with ISO 14567.

4.1.12 Access for machine repairs shall be covered in the manufacturer's available instructions (e.g. machine

repair manual, dealer repair manual, service manual). Access systems for machine repairs can be provided

on the machine or manufacturer's instructions can provide recommendations for use of external access

A means shall be provided to alert the operator whenever a manually retractable access system is not in the

retracted (stored) position if there is risk of damage in the position of use.
4.2.3 Powered retractable access systems
4.2.3.1 Movement shall stop when the control is released.

4.2.3.2 The powered retractable access system shall be visible from the control location or shall have

additional devices [e.g. mirrors, closed-circuit television (CCTV)] for adequate visibility.

4.2.3.3 An interlock shall be provided for the powered retractable access system to prevent machine

movement that could cause damage to the access system through contact with the machine itself (e.g. the

swing of an excavator) when not in the retracted (stored) position. For other machine movement, an operator

warning is sufficient. For a powered retractable access system that transports a person, the additional

requirements given in Annex B apply.

4.2.3.4 In the case of a power failure, it shall be possible to lower the retractable access system or a

secondary access system shall be provided.
4.3 Alternative exit path and opening

4.3.1 An alternative opening from the operator station shall be provided on a surface other than that of the

primary opening. Its dimensions shall be in accordance with Table 1. An alternative exit path shall be provided

at a different location on the machine than that of the primary access system.

4.3.2 The alternative opening shall be clearly marked. If the alternative exit path is not obvious, it shall be

identified.

4.3.3 Vertical ladders are acceptable for the alternative exit path and the distance from the lower step to the

ground shall be a maximum of 700 mm.

4.3.4 The alternative exit path is intended for situations where the primary access system is not available

due to hazards or obstructions. Therefore, it does not need to meet the general requirements given in 4.1,

except when used as part of the secondary access system, in which case it shall meet those requirements.

4.4 Requirements for specific tracked machines with a rotating upper structure

For pipelayers capable of 360° continuous rotation of their upper structure, and for excavators equipped for

piling and drilling, an additional access system is required in the case where access to, and egress from, the

operator's cab is required on a regular basis when the upper structure is rotated to a position other than the

normal parked position as defined by the manufacturer. This additional access system shall meet all

requirements of this International Standard.
