A form traveller is a type of travelling formwork system, which is ususally used in bridge construction, and it plays an indispensable role in bridge construction.It enables repeated construction of structural elements and is commonly used in the free-cantilever construction of post-tensioned box girders and cable-stayed concrete bridges.

Bridge form traveller, also known as a launching gantry, it is a temporary structure used in bridge construction to support the construction of the bridge deck. It is typically a large steel or concrete frame that spans the gap between two piers or abutments and is used to lift and place precast concrete segments or steel girders into position.

The bridge traveller is designed to move along the length of the bridge as bridge construction procedure, allowing workers to build the bridge deck from one end to the other. As each section of the bridge deck is completed, the traveller bridge is moved forward to support the next section.

The advantage of using a traveller formwork is that it allows for faster construction times and reduces the need for temporary supports or scaffolding. It also provides a safer working environment for construction workers, as they can work from a stable platform rather than having to work from heights.

However, the design and construction of form traveller bridge can be complex and require significant planning and engineering expertise. The structure must be able to support the weight of the precast segments or steel girders, as well as the weight of workers and equipment. It must also be able to withstand wind and weather conditions during construction.

How does a Cantilever Form Traveller Work?

A Cantilever Form Traveller is a specialized construction equipment used in the construction of bridges and viaducts. It is designed to support the construction of bridge segments or deck sections in a balanced and incremental manner.

The Cantilever Form Traveller consists of a large steel framework that is supported by a set of temporary supports or towers. It is typically positioned at one end of the bridge or viaduct and gradually extends outwards as the construction progresses.

Here's How it Works:

1. Initial Positioning: The Cantilever Form Traveller is initially positioned at the starting point of the bridge or viaduct, often on one of the piers or abutments.

2. Segment Placement: The first segment of the bridge or deck section is placed on the Cantilever Form Traveller. This segment is typically precast or cast in situ.

3. Balanced Construction: The Cantilever Form Traveller uses its temporary supports or towers to balance the weight of the segment being placed. This ensures that the structure remains stable during construction.

4. Incremental Extension: Once the first segment is in place, the Cantilever Form Traveller gradually extends outward by pushing or pulling itself along the completed segments. This allows for the placement of subsequent segments.

5. Repetition: The process of segment placement, balanced construction, and incremental extension is repeated until the entire bridge or viaduct is constructed.

The Cantilever Form Traveller offers several advantages in bridge construction, such as increased efficiency, reduced labor requirements, and improved safety. It allows for the construction of long-span bridges and viaducts without the need for temporary supports in the water or deep foundations.

It's important to note that different variations of Cantilever Form Traveller exist, and their specific mechanisms may vary. However, the general principle remains the same &#; supporting balanced construction and incremental extension during bridge or viaduct construction.

What are the Advantages of Using a Cantilever Form Traveller?

A cantilever form traveller is a type of constructed travel form equipment used in the construction of bridge decks and other large concrete structures. It is a self-contained system that can be used to construct large sections of concrete in a controlled and efficient manner. There are several advantages to using a cantilever form traveller.

First, bridge traveller allows for the construction of large sections of concrete in a single pour. This means that there are fewer joints in the finished structure, which can improve its overall strength and durability.

Second, a cantilever form traveller is a highly efficient construction method. It allows for the rapid construction of large sections of concrete, which can save time and money compared to traditional construction methods.

Third, form traveller system bridge construction is a safe construction method. The equipment is designed to be self-supporting, which means  that workers do not need to be exposed to the hazards of working at heights or on unstable scaffolding.

Overall, a cantilever form traveller is a highly effective construction method that can be used to build large form traveller bridge construction quickly, safely, and efficiently.

Form Traveller

Product Description

The form traveler (Called Bridge Builder) is common equipment for the construction of large-span pre-stress bridges which use cast-in build method. It can be used to build the segment one section by one section without supports and the help of large cranes.

The form traveler is a load-bearing frame that can slide or roll along the top of the bridge deck. It is anchored and suspended on the constructed beam section. The form traveler can be used for the installation of the next beam section&#;s formwork, reinforcement, pre-stressed pipes, concrete pouring, pre-stress tensioning, grouting and other operations. After completing the cycle of one segment, the form traveler can move forward and fixed to carry out the suspension grouting of the next segment, and so on until the cantilever grouting is completed.
