摘  要:本文主要目的是对5T固定定柱式提升机的结构进行设计，同时要使其能完成所要求实现的相应功能。首先需了解提升机的工作原理、基本结构和系统组成及功能。及其循环、间歇的周期性工作特点，其次要了解一个工作周期包括起升、变幅、回转、下降四个动作，它们分别是由起升机构、变幅机构、回转机构三部分机构来实现完成的。

　　　这次设计的主要分析研究方向是对提升机旋臂梁和旋转部分的机构设计及参数的选择，其中着重对回转机构零部件及其相应技术参数的选择。合理的设计与选择提升机的起升机构、回转机构、变幅机构及金属结构，这样既能很好的实现提升机的运行又不干涉且配合良好。在设计中，起重机整体及零部件都有细说明。

Abstract:This paper mainly 5T fixed hoist fixed column design and analysis of the hoist are required to achieve the corresponding function and structure.Learn hoist works, the basic structure and system composition and function .This paper analyzes the research direction is the hoist arm rotating beam design and its functional part of mechanism design and parameter selection .Crane 's work is characterized by cycles , intermittent exercise. Therefore, in the design to include lifting , slewing , luffing , and metal structures.

　　　Which focuses on the rotary mechanism components and their corresponding choice of technical parameters to achieve both good and not interfere with the operation of hoist and with the good .The design includes hoist hoisting mechanism , slewing , luffing mechanism and metal structure choice.In the design, the crane has a whole and the individual components described in detail .
