Research on Lifting Capacity of Truck Crane Based on Improved Bicubic Interpolation

Abstract:

To accurately compare lifting performance of different wheeled cranes , with discrete original sample data as source data, telescopic boom length and lifting radius as design variables, a surface interpolation mathematical model about crane lifting capacity is built based on improved bicubic interpolation method. On this basis, an analysis is done between a 80 tons truck crane and its upgraded product. The result indicates: under the working conditions of the telescopic boom and maximum counterweight, upgraded product lifting performance is improved significantly, more than 80% of the design points increase above 10%, more than 50% of the design points increase above 20%, and about 10% design points increase less than 7%. The analysis shows that the improved bicubic interpolation method is feasible to predict surface interpolation based on scattered points, it provides accurate data to wheeled cranes lifting performance comparison study.
