Abstract
The utility model discloses a double-beam crane. The utility model provides a double-beam crane with large lifting capacity, small occupied vertical space and increased lifting height. The utility model adopts the technical proposal that the double-beam crane comprises two lifting beams, an electric hoist and a track. The two lifting beams placed horizontally are fixed with two connecting bridges placed horizontally together; and both ends of the electric hoist are respectively fixed with the two connecting bridges together. The electric hoist is fixed above the connecting bridges. Because the crane is changed from single-beam lifting to double-beam lifting, the lifting capacity of the crane is obviously increased; the electric hoist is transferred to the upper part from the lower part of the lifting beam simultaneously, so that the height from a lifting hook to the ground is increased; and the occupied vertical space of the crane is reduced, thereby increasing the lifting height. The utility model is mainly used for cranes.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of double girder crane.
Background technology
Present single-beam crane is that electric block is fixed on a hoisting crane below the lifting beam, the holding capacity of a lifting beam of cause is limited, can not satisfy the need of work of lifting thing weight more than 16T, because of the reel of electric block be located at lifting beam below, the space up and down of causing hoisting crane to take is bigger, suspension hook and ground-surface height reduce, and sling height is shortened.
Summary of the invention
It is big that the utility model provides a kind of hoisting capacity, and the space is little about taking, and increases a kind of double girder crane of sling height.The technical solution of the utility model is finished like this, a kind of double girder crane, include lifting beam, electric block, track, it is characterized in that: two lifting beams of parallel placement are fixed together with two connecting bridges of parallel placement, and the electric block two ends are fixed together with two connecting bridges respectively.Described electric block be fixed on connecting bridge above.Because of hoisting crane changes the twin beams lifting into by the single-beam lifting, the hoisting capacity of hoisting crane is significantly increased; Simultaneously, above electric block is transferred to below lifting beam, suspension hook is increased to the height between ground, the space up and down that hoisting crane takies reduces, and has increased sling height.
Description of drawings
Fig. 1 is a front view of the present utility model; Fig. 2 is a lateral plan of the present utility model; Fig. 3 is a birds-eye view of the present utility model.
Drawing explanation: 1, electric block; 2, connecting bridge; 3, lifting beam; 4, track.
The specific embodiment
The utility model is with two lifting beams 3 of parallel placement and two connecting bridge 2 weld togethers of parallel placement; One end of electric block 1 is fixed by bolts to above the connecting bridge 2, the other end of electric block 1 is fixed by bolts to another above connecting bridge 2, and two lifting beams 3 roll by dolly by the set of wheels that is fixed in the above track 4 corresponding with it and link together.
Claims (2)
1, a kind of double girder crane includes lifting beam, electric block, track, it is characterized in that: two lifting beams of parallel placement are fixed together with two connecting bridges of parallel placement, and the electric block two ends are fixed together with two connecting bridges respectively.
2, a kind of double girder crane according to claim 1 is characterized in that: described electric block be fixed on connecting bridge above.
