Pressure deviation monitoring and early warning in large integrated tower crane support system for super high-rise buildings

Abstract

In super high-rise buildings, the integration of large tower cranes with climbing platforms can enhance the construction efficiency. However, this integration mode significantly increases the load on the tower crane support system (TCSS). Current low-precision manual construction methods can lead to uneven pressures at the support points, potentially causing structural damage and serious accidents. This study proposes a method for monitoring, providing warnings, and optimizing deviations in TCSS pressure to ensure safe and controlled operations. Large-load sensors have been developed to monitor the pressure on TCSS in super-high-rise building projects. The pressure tests revealed that the uneven load distributions at the support points differed significantly from the simulation results. The safety of large integrated construction equipment can be ensured by considering the uneven distribution coefficients of the support pressure and improving the design accuracy of the support points.
