Abstract

Track Tunnel-Stacker Crane is developed by a special crane with the emergence of three-dimensional warehouse, usually referred to as stacker crane. Stacker crane is the most important lifting and transportation equipment in a three-dimensional warehouse, and is one characteristic of three-dimensional warehouse. Its main use is orbit along the roadway in tunnel of high-rise warehouse, put the goods that be located at the mouth of the tunnel into the shelves, or take out goods and delivered to the tunnel mouth, complete the storage operations. 

At the early 70’s of 20th, China started to develop the three-dimensional warehouse with stacker crane, and soon have be widely used in various industries and regions，some have formed serialization. According to incomplete statistics, more than 300 warehouses have been completed now. With the development of modern industry, the technology of stacker crane is being improved. All the world's major industrial countries focus on the development of new products with reliable performance and the use of high-tech，and pay more attention to the practicality and safety. At present, automatic three-dimensional warehouse and stacker crane have become an important component of production management.

This paper starts from the practical problems, and bases on existing equipments. Firstly confirm the overall structure of stacker crane and the draft of parts of the structure. Then use Theoretical Mechanics, Material Mechanics, Machine Design and Manufacturing Technology, and according to relevant design manuals, elaborates on its machinery parts, including: Rack, Running Mechanism, Lifting Mechanism, Loading Stations and Telescopic Fork Mechanism. In the design process, considering the rationality of structure and the economy of the selected materials in order to achieve the mechanical properties of stacker and request of strength, stiffness, running stability, attempt to reach the aim of high-quality, low-cost.
