2) Insistence must be placed upon the use of safety harness. The wearing of safety helmets shall be enforced.
3) Before erection commences, a final check should be made to ensure that the foundations for a static crane, the track for a traveling crane, or the supports for a climbing crane, meet the detailed requirements of the manufacturer, and the Project Construction Department.
4) The crane to be used in erecting a tower crane should be adequate for any lift involved. Therefore the weight of each component (and its center of gravity) should be determined and sufficient margin allowed of error. The suitability of all lifting gear should be carefully considered, particularly in terms of clearance height. Its weight, together with any attachments, should be included in the load.
5) Local weather and wind speed forecasts should be obtained from the MeteorologicalDepartment and erection should only take place if the wind speed is within the limit quoted in the manufacturer’s instructions for erection. Nearby buildings can produce a shielding effect at, or near, ground level which can give a completely false impression of the conditions above building height. In certain cases, tunneling effects can create special dangers.
