Form Traveller (Cantilever Formwork) for Bridge Construction

Hunan Wuxin Intelligence Technology Co., Ltd. (WUXIN) is a leading provider of bridge construction equipment and intelligent construction solutions in China. With extensive experience in high-speed railway, highway, and municipal bridge projects, WUXIN has developed a complete and mature range of Form Travellers (cantilever formwork systems), widely applied in cast-in-situ prestressed concrete continuous girder bridges both domestically and internationally.

1. Product Overview

The Form Traveller is a critical construction system for segmental cantilever construction of continuous girder bridges, mainly used for in-situ casting of prestressed concrete segments. Guided by the principles of safety, structural efficiency, construction productivity, standardization, and intelligent integration, WUXIN form travellers are suitable for:

• High-speed railway continuous girder bridges

• Highway continuous and long-span bridges

• Urban rail transit and municipal bridges

• Bridges with long spans, variable cross-sections, curved alignment, and complex structural behavior

2. Product Types

To meet diverse bridge types and construction requirements, WUXIN offers various form traveller configurations, including but not limited to:

• Diamond-type form traveller

• Triangular-type form traveller

• Top-supported and bottom-supported form travellers

• Form travellers for variable-depth continuous girders

• Standardized form travellers for HSR continuous bridges

All systems are custom-designed according to girder geometry, segment length, construction loads, and applicable codes and standards.
