With the rapid development of Expressway and railway passenger dedicated line construction in our country, bridge engineering across rivers, deep valleys and gorges is becoming larger and larger, technical requirements are higher and higher, construction period is shorter and shorter, tower crane is more and more used in bridge engineering construction. Because of its good performance, our tower crane is widely used in Hangzhou Bay Sea-Crossing Bridge, Runyang Yangtze River Bridge, Shanghai-Rongxi Expressway, Wuhan-Guangzhou Passenger Dedicated Line and other national key projects. The equipment is easy to arrange and wide in scope of application. The attached and climbing tower crane can be widely used in the construction of suspension bridges, cable-stayed bridges and continuous cast-in-situ beams. The tower crane foundation can be shared with the pier foundation and occupies a small area. The equipment has the characteristics of large lifting weight, large lifting height and large construction range. It is very suitable for the overall installation of steel beams of suspension bridges and cable-stayed bridges. Cast-in-place beam hanging basket, mold, material lifting and concrete pouring construction.
