These enable the Appointed Person and the Erection Supervisor 7112-5 decide if climbing should go ahead. When lifting a load from a stack, all persons should be instructed to stand away from the stack in case adjacent materials or objects are displaced.

Business radio communications for 4 tower cranes. Those responsible for the selection of personnel should ensure that the personnel involved in the operation are efficiently organized in order to ensure good team-work in the working situation.

This should include agreed access routes, taking into account ground conditions and also the need for vehicle marshals banksman. It is essential that all personnel in the team are made aware of both this fact and their other duties see 7.

This consists of a lattice steel frame surrounding three sides of the crane tower, with an opening on the fourth. Procedures for the monitoring and reporting of defects such as vibration during the climbing process should also be documented. Overview Product Details BS The risk assessment for this activity might require the use of personal fall protection equipment, see BS Multiple crane types If there is a requirement to operate more than one type of crane, training should be given for each type and, although this would not normally require a re-run of the complete basic training course, it should cater for the differences between types of crane.

Carriers should not be used in the following conditions: If the programme is of several days duration, daily forecasts should be obtained to ensure that the crane can be secured in a suitable configuration if high winds are indicated see Further information on the use of personal fall protection equipment is given in BS Similarly, those companies designing internal courses might wish to fit the basic course to their more special needs.


When radio is used as a means of signalling, the channel selected should be kept clear of all other communications. These devices are a useful aid to the operator when operating on multi crane sites but should not be relied on exclusively in place of the primary be system of work including the crane coordinator, operator vigilance and crane to crane communication using anti-collision radios see Who is this standard for?

BS – Code of practice for safe use of cranes. Tower cranes (British Standard)

An effective planned maintenance system should recognize the possible need to prohibit the use of the crane until essential maintenance work is carried out.

If there are electrical conductors b to the work area, seek advice from the owner of the conductor. Training in safe operation should be provided an as integral part of the course and not separately, nor should the course be altered to suit immediate operational requirements. The method of fastening depends on the magnitude of the tie loads and the strength and construction of the 71211-5.

The systems require adequate: Their competency as instructors should be reviewed periodically and refresher training given if needed. A crane with a cast-in base is mounted on special foundation anchors or an expendable tower section which are cast into a concrete foundation block. While one instructor can deal with a number of trainees when teaching ns a classroom, practical work should have a more individual approach.

Therefore as far as safe crane operations are concerned, the benchmark for safe working practices is the BS series.

All access 71215 should be kept clear of obstructions and other hazards. For over 28 years UK experts have worked together codifying recommendations to address these issues that have been adopted and used by the crane industry. Various BSI electronic information services are also available which give details on all its products and services. Basic principles General Most tower cranes are initially erected to their full height using another crane, either a mobile crane or another tower crane.


Crawler mounted cranes without self-levelling should not be moved over uneven ground when erected.

These should include checks that: The transmitter should only be switched on when operating the crane and be switched off before removing the harness.

Alternatively, other audio or visual methods may be used. Where training has been given in a number of stages in particular, the employee, or employer on their behalf, should keep a record of what training has been carried out. Manuals sometimes deal with dismantling procedures by the simple statement that they are the reverse of erection procedures.

There are also short courses designed to judge the competence of an 7121- operator. In such circumstances the signallers should obtain the agreement of the crane coordinator before carrying out any operation.

Consequently crane operators should be appropriately trained and assessed for the tasks they are required to undertake. In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, sb otherwise requested.

Communication Arrangements for ensuring that all members of the erection team can effectively communicate at all times during the climbing operation should be detailed see Lifting equipment, Occupational safety, Safety measures, Testing conditions, Mechanical testing, Stability, Cranes, Certification approvalVisual inspection testingInspection, Materials handling equipment, Equipment safety.

The total area of the rail bd in use should be fenced off to prevent access by unauthorized persons.

Careful selection of employees before training starts helps to ensure that resources are not wasted.
