The study on tower crane foundation slope model based on inclination feature

Old giant cranes in corrosive environment are in serious hidden danger of structural instability and failure, the modal analysis is an important part of dynamics analysis in the Crane Safety Evaluation to guarantee the safety of cranes. A Modal Analysis of a 28-year old 100t giant shipbuilding tower crane was done using ANSYS. Comparing with the vibration frequencies and modal shapes, Modal analysis shows that the Natural Frequency of the crane reduces from 1.0024Hz to 1.0003Hz, beside all the Modal vibration frequencies (first 10 Order) of the crane are lower than the designed value, means the strength of the tower crane has decreased; the Modal Vibration Frequencies (first 10 Order) of the tower crane are between 1 Hz and 2 Hz. The Mmodal analysis provided theoretical basis for safe use, design and transformation of this crane.

To build the tower crane monitoring system is so important because of the accidents increasing in construction industry. Utilizing lifting weight ring to detect the goods weight is a reasonable way in such a system. Ring size should be considered in the situation to lift different weight goods. Through the definitions of two rings of the smaller and the bigger, the detected weight curves are explored. Through the simulation of tower crane operation, lifting weight curves are obtained and analyzed in different stages of starting, transmitting and ending. The experiments demonstrated that different weight level of goods should select the different size ring, and the detected weight data has its own attributes in different stages.
