Generally, when erecting a tower crane for operation, two factors should be given particular attention: the position or support conditions of the crane and the presence of hazards nearby. The projection of the tower crane beyond the property line should also be considered to avoid potential hazards to the public, including those in private areas and public areas.
It is important to know the maximum pressures or forces that the tower crane can exert on the ground or on other supports and crossbeams. Tower crane manufacturers must provide this information or provide a method and data by which it can be calculated.
Particular care should be taken when assessing wind directions, both operational and non-operational. Strong winds exert significant forces on tower cranes, which are often located near tall buildings. High intensity wind pressure due to funnel (or venturi) and gust effects.Particular care is required in the design and detail of all support structures, connections and anchors.
The floor or foundation, temporary support structures, gratings, gaskets, connections and anchors for tower cranes must be of sufficient strength to withstand the maximum loads, both in operation and out of service, without failure. In particular, the subsoil for stationary tower cranes should be adequately prepared. must be carried out for safety reasons. It is important that the ground on which a tower crane stands has sufficient load-bearing capacity. Seasonal fluctuations in soil conditions must be taken into account in the assessment. Static and dynamic load conditions of the crane.Similarly, structural strength and stability must be considered when supporting the device on or from a structure.
