Scope

This document defines requirements for collision warning systems (CWS) and collision avoidance systems (CAS) that address swing/rotation motion for:

— earth moving machinery as defined in ISO 6165;

— mobile underground mining machinery as defined in ISO 19296; and rock drill rigs as defined in ISO 22935-5;

— road construction machinery as defined in ISO 22242.

This document covers the risk of collision with an intended object between the ground plane of the machine and the top of the machine operator cabin. Thus this document does not cover the risk of collision with parts of the intended objects that are higher than the top of the machine operator cabin. This document does not consider machine height of working tool (e.g. height of boom and arm).

This document covers collision avoidance by motion inhibition or collision warning by providing warning to the operator, prior to initiation of swing/rotation motion around vertical axis of a machine (e.g. excavators) or swing/rotation parts of a machine about an axis (e.g. backhoe portion of backhoe loaders, conveyer part of mobile screens, booms on rock drills).

It does not cover collision avoidance by automatic application of the braking or automatic manoeuvring (e.g. raise bucket) away from the intended object.

There are two cases that the collision risk level (CRL) of a stationary swing/rotation part of machine apply to:

— where there is a risk of collision due to the presence of a stationary intended object before the start of machine swing/rotation, or

— where the intended object itself moves and comes towards the machine before the start of the swing/rotation motion and increases the risk of collision.

Therefore, this document describes two types of collision risk levels (CRL): "rotation angle with stationary intended object" and "distance between the stationary machine and the moving intended object".

The system described in this standard is intended to assist the operator of the machine. The responsibility for safe operation of the machine remains with the machine operator.

This document is not applicable to collision warning and collision avoidance systems installed/manufactured before the date of its publication.

For the purpose of this document, the term ‘machine’ means swing/rotation machine or swing/rotation parts of machine.
