ZDS 7 is developed for track construction, modernization, and maintenance projects that require precise on-site welding of rail sections. It integrates a specialized welding complex that enables rail joints to be created directly along the line, supporting the installation of continuous welded rail systems. This approach improves track durability, reduces the number of joints, and enhances overall ride quality and operational stability.
By enabling welding operations to be carried out at the worksite, the vehicle reduces the need for transporting rails to external facilities, saving time and simplifying logistics. ZDS 7 supports both large-scale track renewal projects and localized repair works, ensuring high-quality, consistent results in demanding working conditions. Its mobility allows teams to perform welding operations across long track sections with minimal disruption to rail traffic.
