A kind of asymmetric cable crane of single column
Technical field
The present invention is used for technical field of bridge construction, more particularly to a kind of asymmetric cable crane of single column.
Background technology
With a varied topography, it is difficult to the earth work of current construction site, such as low lying areas, the ground such as dam, river, mountain valley
The material in area is conveyed, it is necessary to set large span cable crane to convey material to each required place.
With the progress and expanding economy of science and technology, bridge construction is rapidly developed.Cable crane as greatly across
One of conventional construction method of bridge, especially Arch Bridge Construction is spent more and more widely to be paid close attention to.In long-span arch bridge, when
Reinforced concrete arch bridge use cantilever construction when, cable crane be coordinate its construction only selection, cable crane mainly with
The characteristics of transport space scope is wide, starting parcel weight is big is as the prerequisite in Arch Bridge Construction.According to facing that lifting needs
Outage degree cable crane principal mode be the symmetrical cable crane of double tower, without tower cable crane and the asymmetric cable crane of single column.
The existing symmetrical cable crane of double tower, is only applicable to the close engineering of two sides landform.Using double tower cable crane, need
Cable tower is set in two sides, and cable tower anchor ingot is set.Because Arch Bridge Construction major part is the location in leap mountain valley or river valley, and
