Foreword Publishing information This part of BS 7121 wasBritish Standard is published by BSI Standards Limited, under licence from The British Standards Institution, and came into effect on 28 February 200631 January 2016. It was prepared by Subcommittee MHE/3/11, Crane safety and testing, under the authority of Technical Committee MHE/3, Cranes and derricks. A list of organizations represented on this committeethese committees can be obtained on request to itstheir secretary.

Supersession This part of BS 7121British Standard supersedes BS 7121-1:19892006, which is withdrawn.

Relationship with other publications The Lifting Operations and Lifting Equipment Regulations (LOLER) [1] and the Provision and Use of Work Equipment Regulations (PUWER) [2] came into force on the 5th December 1998. Details of the Regulations, an Approved Code of Practice plus HSE guidance can be found in the HSE books Safe use of lifting equipment [3] and Safe use of work equipment [4].

BS 7121-1 provides general recommendations for crane types not covered in an additional part of BS 7121. BS 7121-2 covers in-service inspection, maintenance, thorough examination and, where appropriate, testing for the safe use of all types of crane. SubsequentOther parts of BS 7121 deal with the specific crane types as follows:

• Part 3: Mobile cranes;

• Part 4: Lorry loaders;

• Part 5: Tower cranes;

• Part 6: Derrick cranes;

• Part 7: Overhead/under-hung travelling and goliath cranes;

• Part 8: High pedestal and portal jib dockside cranes;

• Part 9: Container handling cranes;

• Part 10: Rail mounted cranes;

• Part 11: Offshore cranes;

• Part 12: Recovery vehicles and equipment;

• Part 13: Hydraulic gantry lifting systems;

• Part 14: Side boom pipelayers.

When all parts of BS 7121 have been published, CP 3010 will be withdrawn and BS 5744 will be revised to cover manually operated and light cranes only.

Information on the background to the development and use of BS 7121 since the initial publication of BS 7121-1 in 1989 is given in Annex B.

The BS 7121 series has been accepted as representing the consensus of practical experience for the safety onof cranes.

1 Scope This part of BS 7121 gives recommendations for the safe use of cranes permanently or temporarily installed in a work environment. Subjects covered include safe systems of work, management, planning, selection, erection and dismantling, maintenance, inspection, testing,thorough examination, operation and maintenance of cranes, and the planning and management of lifting operations.

This standard is not applicable to the use of cranes:

a) for bungee jumping or similar entertainment activities; or

b) as part of a fully automated storage or production system.

NOTE Annex A and Annex B give recommendations for the training of appointed persons, crane supervisors, crane operators and slinger-signallers. Annex C outlines the features of contract lifts and crane hires. Information on the effect of wind and down-rating of the in-service lifting capacity is given in Annex D. Additional recommendations for the operation of cranes on or adjacent to sites of exceptional hazards are given in Annex E. Additional information on radio communication for lifting operations is given in Annex F.
