This document specifies minimum requirements for design, calculation, examinations and tests of hydraulic powered loader cranes and their mountings on vehicles or static foundations.
This document applies to loader cranes designed to be installed on:
-
road vehicles, including trailers, with load carrying capability;
-
tractors (road or agricultural), where only a towed trailer has capability to carry goods;
-
demountable bodies to be carried by any of the above;
-
other types of carriers (e.g. separate loaders, crawlers, rail vehicles, non-seagoing vessels);
-
static foundations.
This document also applies to loader cranes equipped with special tools or interchangeable equipment (e.g. grapple, clamshell bucket, pallet clamp, etc.), as specified in the operator’s manual.
This document does not apply to loader cranes used on board sea going vessels or to articulated boom system cranes which are designed as total integral parts of special equipment such as forwarders.
The hazards covered by this document are identified in Clause 4.
This document does not cover hazards related to the lifting of persons.
The use of cranes for lifting of persons can be subject to specific national regulations.
This document is not applicable to loader cranes manufactured before the publication of this document. For loader cranes designed before the publication of this document, the provisions concerning stress calculations in the version of EN 12999 that was valid at the time of their design, are still applicable.
