Precast Crane Runway Slabs
Precast concrete slabs designed for use in environments exposed to high concentrated and dynamic loads generated by gantry cranes, cargo handling equipment, and heavy vehicle traffic.
About the product
Precast Crane Runway Slabs
CONTRACK precast crane runway slabs are an advanced system designed for the construction and refurbishment of crane runways and service road crossings at intermodal terminals, ports, logistics centres, and industrial facilities.
The system has been specifically engineered for applications exposed to high concentrated and dynamic loads generated by gantry cranes, cargo handling equipment, and heavy-duty vehicle traffic.
Design
Dedicated design
CONTRACK precast elements enable the construction of ballastless crane runways with high geometric accuracy while reducing maintenance requirements.
Each precast element can be designed with any required length, up to 17 metres, and any width, allowing optimal adaptation to the geometry of the facility and its operating conditions. The height of the crane rail recesses can also be individually adjusted, making the system suitable for both new-build projects and the modernisation of existing crane tracks.
The precise manufacturing of the elements ensures the required track alignment and provides proper, continuous support for the rails along the entire length of the structure.
Advantages of the product
A precast crane runway system offers:
- Manufactured in virtually any length (up to 17 metres) and width to meet the specific requirements of each project.
- The depth of the crane rail recesses can be individually tailored, enabling the structure to be fully adapted to the design parameters and existing infrastructure.
- Elimination of the joint impact ("clickety-clack") effect, resulting in smoother crane operation and reduced dynamic loading.
- No maintenance associated with ballast tamping is required, thanks to the ballastless track structure.
- Rapid installation and early commissioning of the facility.
- Reduced infrastructure maintenance costs through the elimination of ballast tamping operations.
- High durability and excellent resistance to intensive operational loads.
Modernization
Modernization with CONTRACK technology
The CONTRACK system is particularly well suited to refurbishment projects where minimising disruption to existing infrastructure and achieving rapid installation are key requirements. The crane rails embedded in the precast slabs can be replaced without demolishing the concrete pavement, significantly extending the service life of the structure. Rail replacement can be carried out during weekend maintenance windows without affecting the integrity of the precast slab.
The ballastless CONTRACK system also significantly reduces the need for track geometry corrections and routine maintenance associated with ballast tamping and ballast replenishment.
Durability and quality
Durability and initial quality
Manufacturing of the precast elements takes place under controlled factory conditions, ensuring consistently high dimensional accuracy and quality.
The use of proven material technologies, including solutions supported by Sika, provides:
- High resistance to dynamic loads and varying weather conditions
- Long-term durability in demanding industrial environments
- Excellent geometric stability throughout the service life of the structure
