Abstract
This article mainly introduced the entire design theory and design process of bridge-type hoist crane，which focused on the design of the bridge crane operation of institutions and hoisting mechanism．The overall design that mainly includes the bridge type derrick small car to circulate organization and spread the decoration that the motive reaches, the small car circulates an organization calculation.Still have the choice of the choice, electric motor of the choice, allied stalk machine of bearings, decelerate machine of choice and pit in the school.
Keyword:Bridge type derrick;The derrick small car;Book tube;Decelerate a machine.
