1.1This 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.1.2This 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.1.3Piling 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.1.4In addition, this standard applies to diaphragm walling rigs. Additionally, the particular requirements which apply to diaphragm walling equipment are given in normative annex C.
