AS 5144.2 pdf download.Industrial trucks—Safety requirements and verifcation
1  Scope
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 mounted on the load carrier or on the fork arms which are removable by the user are not. Nevertheless, requirements for such attachments are also given by the document. Any regional requirements additional to the provisions of this part of ISO 3691 are addressed in ISO/TS 3691‑7 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, or — when lifting persons.
3  Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 5053‑1 and ISO 12100, and the following apply. 3.1 self‑propelled industrial variable‑reach truck seated-rider-operated, counterbalanced lift truck with one or more articulated arms, telescopic, non- slewing, used for stacking loads and for operation on smooth, level, prepared and consolidated surfaces 3.2 actual capacity at maximum lift height with forks maximum load, Q 2 , specified by the manufacturer that the truck is capable of lifting to its maximum height in normal operating conditions Note 1 to entry: It is equal to the maximum load, with centre of gravity G (see Figure A.1), carried on the fork arms (3.7) at the standard load centre distance, D, as specified in Annex A, and with the boom (3.9) adjusted to its maximum height. It is expressed in kilograms. 3.3 actual capacity at container position with spreader maximum load, Q, with row (d) and height (h), specified by the manufacturer that the truck is capable of lifting to its maximum height in normal operating conditions 3.4 axle locking mechanism designed to stop oscillation of the rear axle so as to improve truck stability 3.5 stabilizer extendable or pivoting mechanical supports used to improve stability of a stationary truck 3.6 lateral levelling act of changing the angular relationship between the boom pivot and the ground in order to adjust the boom pivot to horizontal when the truck is standing on a side slope Note 1 to entry: Used to ensure that the boom (3.9) operates in a vertical plane. 3.7 fork arms device consisting of two or more solid forks, hook‑mounted or shaft‑mounted, that is fitted on the carriage and usually spread manually 3.8 fork arm extension device fitted over the fork arms (3.7) to increase their length 3.9 boom pivoting support member providing radial and telescoping (if equipped) movement of the load‑ engaging means 3.11 bucket device intended for carrying bulk products such as sand, gravel or coal 3.12 overhead guard device fitted to the truck for the purpose of protecting the operator against falling objects 3.13 load backrest portion of the fork carriage serving to restrain the load when the load is tilted rearward or upward 3.14 normal operating position position in which the operator is able to control all functions for driving and load handling as defined by the manufacturer Note 1 to entry: Additional positions may be defined by the manufacturer if it is not possible to control all the functions of the truck from a single position. A rotating seat or stand‑up end‑control truck with more than one operating direction is considered as being or having a single operating position. 3.15 fork carrier device fitted at the end of the boom (3.9) to connect and lock interchangeable attachments without the use of a tool 3.16 auxiliary mast mast at the end of the boom (3.9) intended for reaching greater lifting heights Note 1 to entry: Referred to simply as mast in this part of ISO 3691.
