Types of Bridge Deck Finishing Machines
Cylinder Finishers
Cylinder finishers, such as the C-450 and C-750 from GOMACO, utilize cylindrical rollers to create a smooth surface on freshly poured concrete. These machines are ideal for large projects requiring high productivity and precise finishing. They can handle various paving widths, making them versatile for different applications.
Bridge Deck Pavers
Bridge deck pavers, like the Allen BDF4836B, are designed to tackle full-depth concrete paving on bridges. They can extend up to 90 feet and are customizable to meet specific project needs. Equipped with spud vibrators, these pavers ensure proper compaction and finish quality.
Remote-Controlled Pavers
Remote-controlled pavers, such as the 3600 RC from Bid-Well, offer enhanced safety and control on the job site. The operator can manage the machine’s functions from a distance, minimizing risks and improving operational efficiency. These machines are suitable for complex or large-scale paving projects.
Applications of Bridge Deck Finishers
Highway and Bridge Construction
Bridge deck finishers are primarily used in highway and bridge construction. They provide the necessary precision for creating level surfaces on which vehicles will travel, ensuring safety and longevity.
Overlay Projects
In overlay projects, bridge deck finishers are used to apply a new layer of concrete over existing surfaces. This application is crucial for maintaining the structural integrity and aesthetic of older bridges.
Custom Projects
Many manufacturers, including Allen Engineering and GOMACO, offer customizable options for their machines, allowing contractors to tailor the equipment to specific project requirements. This flexibility is essential for addressing unique challenges in various construction environments.
