4 Safety requirements and/or protective measures
4.1 General
The truck shall comply with the safety requirements and/or protective measures of this clause.
In addition, the truck shall be designed according to the principles of ISO 12100 for relevant but not
significant hazards, which are not dealt with by this part of ISO 3691.
4.2 Modes of operation when lateral stacking
While the truck is lifting, lowering, or travelling at more than 2,5 km/h, it shall not be possible for any part of the lateral reach mechanism to intrude into the racking space. When this lateral reach mechanism is extended, extending or retracting, travelling speed shall be restricted to 2,5 km/h or less.
When a truck is designed for lateraland front stacking, it shall have a device which automatically prevents:
a) travelling at more than 2,5 km/h when the load handling device is in the forward position;
b) turning of the load-handling device in its forward position with a travelling speed of more than 2,5 km/h.
These requirements do not apply if the load handling device is kept within the truck width (excluding guidance system).
Guided trucks operating in aisles with a non-mechanical guidance system shall comply with the automatic steering requirements of ISO 24134.
4.3 Brakes
4.3.1 Operation without guidance systems
For operations without guidance systems, the braking performance shall comply with ISO 6292:2008, Table 2 or 3, group C.
Braking when travelling at more than 9 km/h is subject to regional requirements, additional to the requirements of this part of ISO 3691. See ISO/TS 3691-7.
4.3.2 Operation within guided systems
For operation within guided systems, the braking performance shall comply with ISO 6292:2008, Table 2 or 3, group C.
4.4 Additional requirements for trucks with elevating operator position
4.4.1 Travel speed
Travel speed shall be dependent on braking (see 4.4.2) and stability requirements (see 4.6).AS 5144.3 pdf download.
