Introduction

Lifting machines are an essential part of almost every production, and play a large role in the mechanization of loading and unloading operations. The study of the basis of the design of lifting machines contributes to their development and improvement.

The course design of lifting machines helps to consolidate and deepen the knowledge received by students when studying theoretical courses, as well as contributes to the development of the student's technical thought, and his acquisition of skills in machine linking of individual units and parts of machines, taking into account the possibilities of its assembly, transportation of repairs, etc.

The project on lifting machines is the first independent development of the student of the machine as a whole, consisting of several interconnected mechanisms and metal structures.

In this course design, it is required to design a crane on a fixed column. To do this, calculate the mechanisms: lifting, turning, calculate the steel structure of the crane, and select bearings for the upper and lower journals.
