In this article we preset results of the comparative analysis of two different ways of approximation of actual spatial trajectory of load displacements carried by overhead crane. Sigmoidal functions and polynomials are used to achieve the required agreement with the real trajectories. It is also shown how to obtain maximum accuracy by changing the shape of the trajectory at a fixed displacement time.
