- 1 - Abstract:The graduation project is a bridge crane for the graduation field work done by the tonnage level specific to the design. As China's manufacturing industry, more and more applications crane to which industrial production. Carry a heavy load in the f a c t o r y, ma c h i n e p a r t s u p a n d d o w n , t h e w o r k o f l i f t i n g p a r t s o f s h i p me n t , a s s e mb l y line work should be fixed on the crane is used. The largest number of species of cranes, both in the size of the factory into the application is small tonnage cranes, bridge cranes small tonnage of lightweight parts for a wide range of lifting, in China's machinery industry plays a very important position. However, our current application, or copy large crane behind the technology produced abroad, and has been ap plied in t h e f a c t o r y f o r m a n y y e a r s , a n d s a m e 7 0 t o 8 0 y e a r s o f p r o d u c t s , b o t h i n q u a l i t y o r functionality are not growing to meet the industrial demand. How to design it the lowest cost, rationalize the layout, function modernization is the subject of our study. This d e s i g n i s f o r s m a l l t o n n a g e b r i d g e c r a n e d e s i g n , t h e m a i n d e s i g n elements are 16/3.2t crane structure and operation of institutions, including the bridge structure, calculation and checking the layout, the main beam structure calculation and c h e c k i n g , e n d b e a m s c a l c u l a t i o n a n d c h e c k i n g , t h e m a i n e n d b e a m c o n n e c t a n d r u n the cart and checkin...
