EN 12077-2:1998+A1:2008 (E) 4 Introduction This European Standard is a harmonized standard to provide one means for limiting and indicating devices for cranes to conform to the essential health and safety requirements of the Machinery Directive, as amended. This European Standard is a type C standard as stated in ENV 1070: 1993. The machinery concerned and the extent to which hazards are covered are indicated in the scope of this standard.
EN 12077-2:1998+A1:2008 (E) 5 1 Scope This European Standard specifies general requirements for the application and operating parameters of limiting and indicating devices installed on powered cranes. NOTE Specific requirements for particular types of crane are given in the appropriate European Standard for the particular crane type. This European Standard does not cover erection, dismantling operations, or changing the configuration of a crane. The significant hazards covered by this European Standard are identified in clause 4. This European Standard is applicable to cranes which are manufactured after the date of approval by CEN of this standard. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of, any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

3 Definitions For the purposes of this standard, the definitions given in ENV 1070:1993 and the following definitions apply: 3.1 anti-collision device Device to prevent a fixed load lifting attachment and cranes or parts of cranes from colliding when they are manoeuvred simultaneously in the same space.
NOTE A working space limiter can perform the function of an anti-collision device in certain applications.
EN 12077-2:1998+A1:2008 (E) 6 3.2 configuration The combination of structural members, counterweights, support or outrigger position, hook block reeving and similar items assembled, positioned and erected according to manufacturers’ instructions and ready for operation. 3.3 continuous warning Warning that is given visually by either a flashing or uninterrupted light, or audibly by either a pulsing or uninterrupted sound, and persists throughout the time the condition being indicated exists. 3.4 control station position limiter Device to prevent movement of the control station beyond specified limits, on a crane having a control station that can be moved by powered movement to different positions. 3.5 crane Machine for cyclic lifting or cyclic lifting and handling of loads suspended on hooks or other load handling devices, whether manufactured to an individual design, in series or from prefabricated components. NOTE “Suspended” can include additional means fitted to prevent swinging, rotation of the load etc. 3.6 derricking limiter Device to prevent the raising or lowering of a jib, fly jib, “A-frame” or mast beyond specified limits. 3.7 hoisting limiter Device to either prevent the fixed load lifting attachment from being raised such that it inadvertently strikes the crane structure, or a device to prevent any other specified upper limitation of the load lifting attachment from being exceeded. 3.8 indicator Device which provides warnings and/or data to facilitate the competent control of the crane within its design parameters. 3.9 lowering limiter Device to ensure that the minimum engagement of the lifting medium is maintained at all times during operation, e.g. the minimum number of turns of rope on the hoist drum, or mechanical device to prevent the chain from running out of engagement with the driving mechanism. 3.10 motion limiter Device which restricts a crane motion or initiates the stopping of the motion. (See examples in 5.6.1.1). 3.11 overturning moment (for the purpose of 5.3.1) The product of the rated capacity and the reference outreach. 3.12 performance limiter Device which automatically prevents a design performance characteristic from being exceeded. 3.13 rated capacity Load that the crane is designed to lift for a given operating condition (e.g. configuration, position of the load).
EN 12077-2:1998+A1:2008 (E) 7 3.14 rated capacity indicator Device which gives, within specified tolerance limits, at least a continuous indication that the rated capacity is exceeded, and another continuous indication (on certain crane types - see 5.5.1.2(a)) of the approach to the rated capacity. 3.15 rated capacity limiter Device that automatically prevents the crane from handling loads in excess of its rated capacity, taking into account the dynamic effects during normal operational use. 3.16 reference outreach Horizontal distance between a vertical line through the centre of gravity of a load and the corresponding tipping line. 3.17 slack rope limiter Device to automatically prevent dangers from slack rope situations. 3.18 slewing limiter Device to prevent slewing beyond specified limits. 3.19 telescoping limiter Device to prevent the extension or retraction of a member beyond specified limits. 3.20 travelling limiter Device to prevent all types of movement along rail tracks or runways beyond specified limits. NOTE Travelling covers terms such as ‘traversing’, ‘crabbing’ and ‘trolleying’. 3.21 working space limiter Device to prevent a fixed load lifting attachment and/or parts of the crane from entering a prohibited space. NOTE Working space limitation is often achieved by a combination of different limiters. 4 List of significant hazards Table 1 shows a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and foreseeable misuse. It also contains the corresponding cross-references to certain Parts of EN 292, and the relevant clauses in this standard that are necessary to reduce or eliminate the risks associated with those hazards.
