The appointed person should be given the necessary authority for the performance of all these duties and, in particular, authority to stopthe operation whenever they consider 1721-5 danger is likely to arise if the operation were to continue.
This code of practice therefore aims to: Subscribing members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.
The crane safety devices should not be regarded as routine means of stopping the motion s. NOTE The appointed person may delegate the task of preparing the method statement to another person; however they retain responsibility for the method statement. The means should be chosen following a site specific risk assessment, ensuring that persons can be rescued promptly to prevent the onset of suspension trauma.
The risk assessment for this activity might require the use of personal fall protection equipment, see BS The lower collar, at the bottom of the tower, takes vertical forces and part of the overturning moment, whilst the top collar takes the horizontal forces of the remainder of the moment.
There should be sufficient time for the instructor to demonstrate each part of the practical training and then for each trainee to practice the skills while also being able to learn from observing other trainees. NOTE 2 Complete insulation of the crane hoist rope or use of clean dry webbing lifting attachments can also prevent stray currents. Rescue arrangements Arrangements should be made for the rescue of personnel from the tower crane including: In this case they should be treated as mobile cranes for thorough examination in accordance with BS Once at the top of the tower the frame is secured to the underside of the crane slewing section.
Balancing is achieved by either lifting a specified weight normally another tower section and moving it to a specific radius or using the self weight of the jib and hook block. The BS series has been accepted as representing the consensus of practical experience for safety on cranes.
The vertical and horizontal forces are unlikely to be uniformly distributed and an allowance should therefore be made for these and for any other unpredictable effects.
For details of these and other benefits contact Membership Administration. The requirement for an appointed person with appropriate training and experience ba applies to installation operations. The self-levelling function has a limited range of correction and great care should be taken when travelling over uneven ground. Consideration should be given, where appropriate, to stocking certain expendable items and other parts to minimize down time in the event of crane breakdown.
During the carrying out of the lifting operation, hand signals and any voice instruction to the crane operator s should only be given by one person at a time.

This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations. If there is access by other people, e.
The assessment should evaluate the risks 1721-5 and the nature and extent of any measures required to mitigate those risks. These should have their indicators located in clear view of the crane operator. This should include agreed access routes, taking into account ground conditions and also the need for vehicle marshals banksman.
The signaller may be given the operations between personnel.
These might include choosing a unique frequency to avoid interference from other sites, ensuring that batteries are fully charged and that spare handsets are available in case of breakdown. If the crane supervisor is also a crane operator, then the crane supervisor should not operate any crane involved in the lifting operation being supervised.
Similarly, those companies designing internal courses might wish to fit the basic course to their more special needs.
The results of the risk assessment should be recorded in writing and used in the preparation of the method statement see 6. Information regarding online access to British Standards via British Standards Online can be found bss http: Assessment It is important that all personnel in the erection team are regularly assessed to ensure that they can carry out their duties safely and effectively.
This distance should be either: The Plan should include information to allow all parties involved in the specification, installation or use of cranes to be made aware of the fundamental criteria and planning issues needed to ensure that lifting operations are initiated and proceed in a logical and safe manner.
The crane should be equipped with power lowering. Therefore as far as safe crane operations are concerned, the benchmark for safe working practices is the BS series.
Slinging points should be identified for all components. Particular emphasis should be placed on contingency arrangements and those being briefed should be encouraged to ask questions and seek clarification on any points on which they are not clear. Personnel working on tower cranes should wear suitable footwear for climbing structures.
Usage or storage of the crane in a corrosive environment can also cause deterioration of the crane structure and this might require more extensive examination. NOTE Responsibilities for insurance in terms of the crane, personnel, the load and third parties might also need to be clarified.
The Air Navigation Order These might include choosing a unique frequency to avoid interference from other sites, ensuring that batteries are fully charged and that spare handsets are available in case of breakdown.
NOTE Self-erecting tower cranes have been addressed briefly in this document.
The erection supervisor should be in close liaison bss the site management and should carefully consider any comments or warnings that management, any members of the site team, or any other appropriate person or body make.

Certain safety equipment, for example helmets, safety spectacles and fall protection equipment, can deteriorate with age and should therefore be considered for renewal periodically. Stability is normally obtained by means of ballast weights which should be adequately secured to prevent accidental displacement or bx, and the detail of the ballast should be on the notice near the base of the crane giving the crane capacities.
