 The Design and Computation of Gantry crane
Abstract
 Gantry crane is currently used for raising the heavy object. This kind of equip-ments has many advantages.Following are the typical ones, First the construction is simple;Second it is safe; Third it is wildly used. Within the increasing desire, the problem of safe,eeonomic efficiency and enduring is more and more concerned by user.through a series of parameters such as complete machine properties are taken into account, and the utility and practicability are emphasized. the effect to design of main parameters in whole machines is preliminary eva luated, in  order to provide theories accordance with referring valuable in design of gantry crane.This  present paper introduced the 10 ton gantry crane design, the parameter computation and the major parts intensity examination.  The anticipated goal as well as the domestic and foreign   Gantry crane  development present situation the main introduction chooses this topic which in the this article first chapter of introduction the background significance, studies which this topic to have to solve the main question, can achieve. The second chapter introduces the hoisting mechanism  major component structure and design , including the design and choice of reducer, the barrel structure and winding reel method of design. Third chapter is the girder  parameter choice and the design calculation, chooses the basic parameter to prepare for the next step of computation,  The forth chapter is the installation of gantry crane and attention to issues. Gantry crane design satisfies the design project description request.
