  Structure of Double Girder Overhead Crane 
  
 
  The double girder hoist is widely used for lifting heavy materials in plants, warehouse, and material stocks. It’s composed with Girder frame, Crane travel device, and the trolley with lifting and moving device. The trolley and hoist run on a rail installed on top of the bridge girders, and the cranes can be either top running or under running in design. Assemble the moving table on the outside of the two main girder, one side is prepare for the assemble and maintenance the crane move device, another side is prepare for the assemble of the trolley conductor device. 
  
 
  There are full field of view Cabin suspend under the main girder, there are joint control desk or single control box packed within the Cabin, assemble the sidelong ladder between the Cabin and moving table, The main girder joint with the two side end carriage which with the joint point in the middle.
