The Modeling of Main Hoist Mechanism of Quay Container Crane

Abstract

The promoting international trade makes the container transportation more important than ever. So more and more researchers are interested in design and research of quay container crane. A quay container crane consists of gantry, trolley, main hoist, luffing gear and spreader etc. It is of significance to study the mechanism for designing and manufacturing cranes. This paper analyses the transmission mechanism of main hoist of quay container crane, and builds the mathematics models of the steel wire of spreader and the part from electromotor to convolution, to analyses data translation from electromotor to spreader of main hoist in quay container crane. So, it is possible to simulate the motion curve of the spreader of quay container crane in a computer program with the results gained from this paper. Another significance of this paper is the application of the method dealing with high factorial equations.
