Combined with the practical construction condition of the curve cast-in-site continuous beam, the article stresses to set forth the control of the sectional construction alignment of the cantilever form traveler and the construction technology of the closure section, and introduces some key problems met in the course of construction and some error-correcting methods.

The optimization scheme comparison of the anterior suspension system of rhombic hanging basket;

Design and application of rhombic hanging basket in Wujiang bridge works of Silin;

Combining with some four-span prestressed continuous bridge engineering in Xi an,the monitoring controls of stress state and geometric alignment during cantilever hanging basket construction of long-span bridge are introduced.

Jiuzhen Super-large Bridge Project of Zhangzhao Expressway uses the diamond truss type form traveler cantilever concreting method to construct.

Taking Huanglongchun Grand Bridge as an example,the paper introduces the structure and working principle of the rhombus hanging basket,and studies the application and deformation of the rhombus hanging basket in cantilever construction in experiments,which is of great significance for construction monitoring.
