摘  要

 在實際生產過程中往往需要進行大型設備的組裝、拆卸、裝運等。這些設備不論從體積到重量都很大，所以需要大型的起重機對其進行搬運，橋式起重機俗稱天車是一種用來起吊、放下和搬運重物、并使重物在一定距離內水平移動的起重、搬運設備。橋式起重機由小車、大車組成、主鉤為提升機構。橋式起重在生產過程中有著重要應用。

Abstract
 Often needs to carry on large-scale equipment's assembly, the disassemblage, shipping in the actual production process and so on. No matter these equipment are very big from the volume to the weight, therefore needs the large-scale hoist crane to carry on the transporting to it, the bridge-type hoist crane popular name overhead traveling crane is one kind uses for to hoist up, to lay down with the transporting heavy item, and causes the heavy item the level migration to lift heavy objects, the loader in certain distance. The bridge-type hoist crane by the car, the large cart is composed, the main hook for the raising mechanism. Bridge-type lifts heavy objects in the production process has the important application.
