Overhead Form Travellers

Generally, Form Traveller consists of main trusses, front and rear crossgirders, suspension, formwork, and walking systems. The main trusses are the main load - bearing components, and the front and rear cross - girders connect the main trusses to support the formwork. The suspension connect the formwork to the main trusses to adjust the height and position of the formwork. The walking system enables the Form Traveller to move along the bridge axis.

There are several types of Form Traveller, such as truss - type, triangular - type, diamond - type, and cable - stayed - type. Each type has its own characteristics and application scenarios. For example, the truss - type Form Traveller has high structural strength and stability, suitable for large - span bridge construction; the triangular - type Form Traveller is simple in structure and easy to install and disassemble, suitable for small - and medium - span bridge construction.
