Truck Mounted Bridge Launching

Truck Mounted Bridge Launching is a method used for the construction of bridges in the supply class Bridges, Fixed And Floating, which falls under the supply group Prefabricated Structures And Scaffolding.

In this method, a specialized truck-mounted launching system is used to assemble and install prefabricated bridge components. The truck is equipped with hydraulic jacks and a launching nose, which is used to push the bridge segments into position.

The process typically involves the following steps:

1. Site preparation: The construction site is prepared, including the installation of temporary supports and foundations.

2. Prefabrication: The bridge components, such as beams and girders, are prefabricated off-site according to the required specifications.

3. Transportation: The prefabricated components are transported to the construction site using trucks or other suitable means.

4. Assembly: The truck-mounted launching system is positioned at one end of the bridge. The bridge segments are then lifted and connected to form the bridge span.

5. Launching: The hydraulic jacks on the truck are used to push the bridge segments forward, gradually extending the bridge span.

6. Alignment and adjustment: As the bridge is being launched, it is continuously monitored and adjusted to ensure proper alignment and levelness.

7. Completion: Once the bridge span is fully extended and aligned, additional construction activities, such as the installation of deck panels and railings, may be carried out to complete the bridge.

Truck Mounted Bridge Launching offers several advantages, including faster construction time, reduced labor requirements, and minimal disruption to traffic during construction. It is commonly used for the construction of temporary or permanent bridges in various settings, including highways, railways, and waterways.
