ISO 24134:2006 specifies the safety requirements for controls and control systems for the following automated functions of industrial trucks: steering (excluding direct mechanical guidance); travel; lifting and lowering operations; load manipulations, e.g. rotation, reach, slewing, tilting, clamping; combination and/or sequence of these movements. ISO 24134:2006 is intended for use in conjunction with one or more of the applicable parts of ISO 3691. It is not applicable to, and does not include, requirements for the following: safety equipment (e.g. devices for height limitation, speed limitation) used to override driver control; operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields); operation in environments subject to special rules (e.g. potentially explosive atmospheres); electromagnetic compatibility; transportation of passengers; handling of loads, the nature of which could lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials). Limitations in the scopes of the applicable parts of ISO 3691 also apply to ISO 24134:2006.
