This part of ISO 3691 gives safety requirements and the means for their verification for self-propelled industrial variable-reach trucks and variable-reach container handlers/reach stackers as defined in ISO 5053-1 (hereafter referred to as trucks), equipped with forks or integral load-handling devices for normal industrial duties (e.g. fork arms or means, such as spreaders, for handling containers).
It is not applicable to
— rough-terrain variable-reach trucks,
— rough-terrain variable-reach trucks for handling containers,
— machines designed primarily for earth-moving (e.g. loaders and dozers), even when their buckets and blades are replaced with forks,
— machines from which the load can swing freely in all directions.
For the purposes of this part of ISO 3691, fork arms and integrated attachments are considered to be a part of the truck, whereas attachments/equipment/tools mounted on the load carrier or on the fork arms which are removable by the user are not. Nevertheless, for interchangeable equipment, which is assembled with the truck by the operator in order to change the function of, or attribute a new function to, the truck, this document does provide requirements for:
— the interface with the truck,
— protection of the operator in the normal operating position from crushing and shearing hazards,
— operating and maintenance instructions,
— load charts,
— provision for transportation, and,
— indicator lights for attachments for lifting containers
Any regional requirements additional to the provisions of this part of ISO 3691 are addressed in EN 16307-2:20XX and ISO/TS 3691-8.
This part of ISO 3691 deals with all significant hazards, hazardous situations or hazardous events, as listed in Annex B, with the exception of the following, relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
It does not establish requirements for hazards that can occur
— during construction,
— when using trucks on public roads,
— when operating in potentially explosive atmospheres,
— when lifting persons, or
— during dismantling, disabling and scrapping.
This standard does not provide requirements for:
— tools, lifting accessories or removeable attachments, which do not change the function or attribute a new function, mounted on the load carrier or fork arms
— attachments/equipment mounted on the load carrier or on the fork arms which are removable by the user and which change the function or attribute a new function, except as stated above,
— the reliability of control systems and performance requirements for safety related parts of control systems, or
— the requirement for fitting an enclosed cab, whether pressurised or not.
