28、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. BS EN 12077-2:1998+A1:2008Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS,

29、13/05/2009 03:02, Uncontrolled Copy, (c) BSIEN 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 cran

30、e 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 Standa

31、rd 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 t

32、ext 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.

36、 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 c

38、nd 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 ti

39、me 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 li

40、fting 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 t

41、o 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 l

42、imitation 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

43、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 exam

44、ples 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

45、 to lift for a given operating condition (e.g. configuration, position of the load).

46、cified 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 load

47、s 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 pr

48、event 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 tra

49、cks 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.
