This part of BS 7121 provides recommendations for the safe use of mobile cranes (see 3.5<\/b>) used for a wide variety of lifting operations in numerous locations, and is intended to be used in conjunction with BS 7121\u20111, which gives general recommendations for all types of cranes, and BS 7121\u20112 (all parts), which gives general guidance on inspection, testing and examination of all types of cranes.<\/p>\n

\n

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 not permitted to travel with suspended loads. Semi-mobile cranes include wheeled and crawler\u2011mounted 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 fixed base with outriggers are also covered by this part of BS 7121.<\/p>\n<\/blockquote>\n

This part of BS 7121 is not applicable to rail-mounted cranes, cruciform self-erecting tower cranes, cranes covered by other parts of BS 7121, or to the use of cranes:<\/p>\n

    \n
  1. \n

    for bungee jumping or similar entertainment activities; or<\/p>\n<\/li>\n

  2. \n

    specifically designed for railway applications; or<\/p>\n<\/li>\n

  3. \n

    as part of a fully automated storage or production system.<\/p>\n<\/li>\n<\/ol>\n

    While the recommendations in BS 7121\u20111 are for planning, management, selection of equipment and personnel, etc., for safe lifting with all types of cranes, this part provides specific recommendations for safety when dealing with the hazards caused by mobility and the diversity of locations for mobile crane lifting operations.<\/p>\n
