The Arab Contractors company has 16 complete cantilever carriage systems.
The cantilever carriage system is used for the construction of the superstructure. It helps in conquering the adverse site conditions (i.e. over water, terrain areas, high elevations, etc.) A typical cantilever carriage set consists of a steel truss that is fixed to the stump. Thus, a shuttering and working platforms can be provided for pouring the superstructure on stage (i.e. usually between 3 to 5 m). The construction procedures start by constructing the stump (i.e. part of the superstructure over the columns). The length of the stump is usually around 15 m. Then, the cantilever carriage sets are assembled on both sides of the stump. After concreting and stressing each stage, the carriage moves to the next position. The key element here is preserving all the time the balance between the two cantilevers at both sides of the bridge.
The Arab Contractors Company used the cantilever carriage system in several projects :
