Form Travelers are mainly used in the construction of cast-in-place balanced cantilever Bridges, and are suitable for short Bridges with long spans as well as bridge construction in some areas with complex terrain and inconvenient transportation. For instance, in the construction of Bridges spanning complex terrains such as rivers and valleys, hanging baskets can reduce the use of temporary support structures, lower construction costs and enhance construction safety.

Technical characteristics

Structural design: The hanging basket is typically composed of a main truss, a walking and anchoring system, a sling system, a bottom formwork platform and its formwork support system, etc. Take the Guangchengtang Bridge as an example. Its hanging basket is designed in a diamond shape and consists of a main truss, a walking and anchoring system, a sling system, a bottom formwork platform and its formwork support system, weighing approximately 50 tons.

Working principle: The hanging basket operates through a free erection sequence or a linear movement erection process. In the construction of the cast-in-place balanced cantilever bridge, the hanging baskets move gradually along the bridge piers to complete the concrete pouring of each section.
