Abstract
With the development of science and technology, improve machine replacement, in the manufacturing industry plays an important position is. Gantry walk small hoist is a kind of circulation, intermittent movement machinery, mainly for the items of loading and unloading. This design is based on the relevant teaching material hoist, field investigation and relevant material after reference .and carry on the design. The main performance parameters including: to improve quantity, work span, lifting height and the speed of work, etc.
This design is mainly to the two tons of gantry hoisting machine can walk small of lifting mechanism and walks the organization design, and calculation of ascension in the domestic and foreign development prospect and machine hoist the significance of the study. In the design of the main girder again check, the choice of materials and walks the organization operation to demand higher and detailed calculation. And to the role of related components, such as design and choose the choice of detail do, and points out that the rationality and the importance of sex. In this design design CAD software application, word document editing, etc
Key words: to improve frame and institutions, during operation organization, CAD and checking
