The form traveler is the main equipment in cantilever construction. Cantilever construction by form travelers refers to a method for casting longer-span cantilevered girder bridges using suspended baskets to cast segments in place. It eliminates the need for scaffolding and large cranes, offering advantages such as light structure, simple fabrication, and no counterweight.

mainly including: main truss, guide beam system, bottom support system, walking system, ladder guardrail, rear anchoring system, bottom support protection, and full protection system.
· Main Truss: as the core of the diamond-shaped form traveler, it acts like the human skeleton, bearing most of the loads during construction. It is composed of two diamond-shaped main trusses firmly connected by transverse connecting systems.
· Guide Beam System: plays a key role in supporting the formwork, providing a stable foundation for the formwork.
· Bottom Support System: is a critical structure for placing the bottom formwork.
· Walking System: enables the form traveler to move on the completed beam segments, serving as an important guarantee for the gradual advancement of cantilever construction.
· Ladder Guardrail: provides a safe operation and walking platform for construction personnel.
· Rear Anchoring System: performs a vital anchoring function during concrete pouring to prevent the form traveler from overturning and ensure construction safety.
· Bottom Support Protection & Full Protection System: are important facilities to ensure construction safety and prevent falling objects from causing injuries.
