30、recommendations for the safe use of mobile cranes (see 3.5) used for a wide variety of lifting operations in numerous locations, and is intended to be used in conjunction with BS 71211, which gives general recommendations for all types of cranes, and BS 71212 (all parts), which gives general guidanc

31、e on inspection, testing and examination of all types of cranes.NOTE Mobile cranes are manufactured in many different forms. Mobility is either by means of wheels or crawler tracks. Cranes can be fully mobile and able to travel with rated capacity loads suspended (pick and carry), or semi-mobile and

32、 not permitted to travel with suspended loads. Semi-mobile cranes include wheeled and crawlermounted cranes, fitted with stabilizers or outriggers; and cranes that, due to size and weight, are taken to the work site in parts and assembled at the site. Cranes that are assembled on site to work from a

33、 fixed base with outriggers are also covered by this part of BS 7121.This part of BS 7121 is not applicable to railmounted cranes, cruciform selferecting tower cranes, cranes covered by other parts of BS 7121, or to the use of cranes:a) for bungee jumping or similar entertainment activities; orb) sp

34、ecifically designed for railway applications; orc) as part of a fully automated storage or production system.While the recommendations in BS 71211 are for planning, management, selection of equipment and personnel, etc., for safe lifting with all types of cranes, this part provides specific recommen

35、dations for safety when dealing with the hazards caused by mobility and the diversity of locations for mobile crane lifting operations.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

41、 the characteristics of the MCWP they are required to operate where those characteristics differ from machines on which they have been trained3.2 fly jibadditional jib fitted to the main boom tip to extend or offset the reachNOTE 1 The main purpose of the fly jib is to increase the overall length of

42、 the main jib and to thereby increase the effective height of the lift. The fly jib can be set in the same line as the axis of the main jib, or can be offset at a fixed angle. If the fly jib is offset at an angle, the crane can be used to reach in over a structure (effectively increasing the radius)

43、. The greater the angle of offset, the higher the structure that can be negotiated and/or the further the crane can reach in to lift the load; but because of the increased stresses induced at the fly jib attachment point, only a reduced load can be lifted. A fly jib can be extended by insertion of i

44、ntermediate lattice sections, but usually it is of shorter length than the main jib.NOTE 2 Fly jibs can be of telescopic box construction but, because of a relatively high selfweight that can reduce their lifting capacity considerably, these are of limited application only.3.3 freeonwheelsability to

45、 lift loads with a stationary, wheeled crane without the use of outriggers or stabilizers3.4 loadenhancing equipmentequipment fitted to a mobile crane to increase the margin of stability or to reduce the structural stress within the loaded members, allowing the rated capacities for the crane configu

46、ration to be increasedNOTE Load-enhancing equipment may be known by a proprietary name (e.g. “Superlift” 1).3.5 mobile craneselfpowered crane with a boom, which may be fitted on a mast (tower) and capable of travelling laden or unladen, without the need for fixed runways and which relies on gravity

47、for stability, the chassis of the crane not having any capability to carry goodsNOTE 1 Mobile cranes can operate on tyres, crawlers or with other mobile arrangements. In fixed positions, they can be supported by outriggers or other accessories increasing their stability.NOTE 2 The superstructure of

48、mobile cranes can be of the type of full circle slewing, of limited slewing or non-slewing. It is normally equipped with one or more hoists and/or hydraulic cylinders for lifting and lowering the boom and the load.NOTE 3 Mobile cranes can be equipped with telescoped booms (pinned), telescopic booms,

49、 articulated booms, or lattice booms or a combination of these of such a design that they can readily be lowered.NOTE 4 Loads can be handled by hook block assemblies or other load-lifting attachments for special services.SOURCE: BS EN 13000:2010+A1:2014, 3.18, modified1 Superlift is a trade mark owned by Terex South Dakota, Inc., 500 Oakwood Road, Watertown, USA, 57201, and is the trade name of a product su
