The box girder lifting device is characterized in that pin holes are formed in the two inclined girders, two pin holes matched with the inclined girder pin holes are formed in the two ends of the box girder lifting device, and the hollow plate girder lifting structure is installed on the box girder lifting device by penetrating the same pin shaft into the box girder pin holes and the inclined girder pin holes together.

The cross beam is fixedly provided with two upright posts which are positioned on two sides of the box girder lifting appliance mounting position, and the upright posts are supported at the bottom of the box girder lifting appliance and are connected and fixed with the cross beam through the hanging rod.

And a plurality of web members are connected between the cross beam and the two oblique beams.

The beam is composed of two I-shaped steels arranged side by side and two sealing plates respectively packaged on the surfaces of the two I-shaped steels.

The oblique beam is composed of two channel steels and two connecting plates respectively packaged on the surfaces of the two channel steels.

The utility model has the advantages that:

directly settle the case roof beam hoist in case roof beam hoist arrangement position department and be connected with two sloping beams, thereby having made with the help of original case roof beam hoist and to carry out swift convenient dismouting between hollow slab beam hoisting structure and the case roof beam hoist, not only operation use labour saving and time saving, it is few to consume manual work and machinery, and also realized the purpose that same hoist and mount longmen hoisted hollow slab beam and case roof beam, just also can pile the roof beam district with the case roof beam and establish to one with the hollow slab beam, utilize hoist and mount longmen on the same track to hoist hollow slab beam and case roof beam respectively, hollow slab beam piles the roof beam district and can compromise the use with the case roof beam district, the pile roof beam district utilization ratio of precast beam factory has been improved, still saved equipment input cost when having saved the place resource, manufacturing cost has been greatly reduced from this.
