This standard specifies safety requirements for piling equipment suitable for the following purposes: a) Construction of foundations, slurry walls or retaining walls, using piles or other longitudinal elements; b) Removal of piles; c) Installation of drain - or injection elements. The pile material can be timber, concrete (precast or cast in situ) or steel (tubes or rolled sections). Additionally, piles may have an interlocking feature to enable adjacent piles to be joined together. This European standard deals with all significant hazards pertinent to piling equipment, when they are used as intended and under the conditions foreseen by the manufacturer (see annex A) associated with the following: Transport of equipment; Rigging and dismantling of equipment; Equipment in service and out of service; Moving of equipment between pile positions; Storage of equipment. This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. Piling equipment includes: a) Piling rig consisting of carrier machine (crawler, wheel or rail mounted, floating), leader attachment, leader or other guiding systems, e. g. direct mounted, boom supported, swinging, guide cage or free riding; b) Pile installation and extraction equipment, e. g. impact hammers, extractors, vibrators or static pile pushing/pulling devices; c) Accessories, e. g. pile caps, helmets, plates, followers, clamping devices, pile handling devices, pile guides, acoustic shrouds and shock/vibration absorbing devices, power packs/generators and personnel lifts or platforms. In addition, this standard applies to diaphragm walling rigs. Additionally, the particular requirements which apply to diaphragm walling equipment are given in normative annex C. If the carrier machine of a piling rig consists of an excavator, crane etc. the carrier shall be covered by its own standards to the extent the requirements of this standard are not applicable. If piling equipment is also intended to operate with drilling attachment, EN 791 shall be complied with, too, except for the stability requirements which shall be in accordance with 4.1 of this European Standard (EN 996). When operating in explosive atmosphere, additional requirements are needed which are not contained in this standard. Informative Annex E is provided for the information and guidance for manufacturers of grouting and injection equipment for use in the foundation industry in the absence of a European Standard for this equipment. It is not a normative part of this standard and does not contain sufficient guidance on safety requirements and measures to achieve conformity with the essential safety requirements of any EC Directive. This European Standard applies primarily to machines which are manufactured after the date of approval by CEN of the standard.
