scope:

This Standard applies to new or unused wheeled or tyred, self-propelled, non-rail-bound, mobile machines for use in underground mines.

This Standard describes the technical aspects and procedures necessary for the design, performance, and testing of core design and safety requirements.

This Standard covers general requirements only. Requirements common to a variety of underground mining mobile equipment are grouped in this Standard. The remaining Standards in the series state requirements for braking and specific types of power trains. See Annex DA for additional information on how to apply the CSA M424 series of Standards.

For utility / service / support machines, this Standard only includes provisions to address the risks associated with the mobility (movement of the whole machine from one location to another). Risks for the additional functions (e.g., scaling, concrete spraying, bolting, charging drilling attachment) are not covered in this Standard.
