Abstract

The invention relates to a through-typed double-trolley bridge-typed crane, comprising a cart, a main beam arranged on the cart, a first cargo trolley and a second cargo trolley; the first cargo trolley comprises a matter-fetching device, a left flap frame and a right flap frame; the matter-fetching device is hung on the left flap frame and the right flap frame by a lifting sling, and a U-shaped space is formed on the upper surface of the lifting sling and the matter-fetching device of the first loading trolley; the second loading trolley comprises a frame, a traversing mechanism arranged on the frame and the matter-fetching device hung on a traversing part by the lifting sling; rails which support the second loading trolley are arranged between a guide rail for supporting the left flap frame of the first loading trolley and a guide rail for supporting the right flap frame of the first loading trolley; the extending directions of all the guide rails are in parallel and the second loading trolley can pass through the U-typed space.

Description

technical field [0001] The invention relates to a crane, in particular to a bridge type crane. Background technique [0002] Bridge type crane is a kind of crane that is widely used at present. It has two types: bridge type crane and gantry type crane (such as container loading and unloading bridge, gantry crane, etc.). Whether it is an overhead crane or a gantry crane, they all have carts, girders, etc. There is a track on the main beam, and the trolley works on this track. [0003] There is only one track on the main girder of the existing bridge type crane, and this track can only be used for one trolley to walk independently throughout the whole process, or for several trolleys to walk on the track according to the front and back sequence. The trolleys cannot meet each other, nor can they overtake each other. This structural form limits the space utilization rate and loading and unloading speed of the crane to a large extent. [0004] In addition, the cabs of a large...
