The highway construction gantry crane is specially developed for hoisting and erecting concrete bridge beams onto bearing supports during highway infrastructure projects. Its complete structure consists of main girders, longitudinal flat cars, support assemblies, transverse and longitudinal travelling systems, hydraulic power units and electrical control systems, enabling integrated beam lifting, transportation and placement operations.
This construction gantry crane is available in two configurations: rail-mounted and step-type models. The rail-mounted type is mainly applied for bridge beam erection projects with maximum beam lengths of up to 30 meters. The step-type model requires no track installation, with supporting legs directly positioned on bridge bearings instead of the bridge deck, avoiding additional pressure loads and preventing structural damage to completed bridge components.
To meet the diverse requirements of modern highway engineering, Weihua provides a complete range of customized highway gantry crane solutions. These cranes are designed to adapt to complex construction conditions, including skew bridges, curved bridges, dislocation bridges, heavy girder erection, variable beam construction, bidirectional operation and tunnel construction environments.
Precise beam alignment and positioning system
Supports horizontal alignment and one-time precise beam positioning, simplifying bridge erection procedures and improving construction efficiency during highway infrastructure projects.
Adaptable structure for complex bridge construction
The professionally optimized structural design adapts to inclined and curved bridge construction requirements, providing strong scenario compatibility for diversified engineering conditions.
Lightweight modular design for efficient installation
The lightweight overall structure enables convenient and rapid transportation, on-site assembly and dismantling, effectively shortening project preparation cycles and improving construction flexibility.
High-precision and stable construction performance
The crane delivers stable and reliable working performance with minimal longitudinal cantilever deflection, ensuring high construction accuracy, operational safety and consistent bridge beam erection quality.
Bridge deck protection during travelling operation
The supporting legs avoid direct contact with the bridge deck during longitudinal movement, effectively reducing surface pressure and protecting completed bridge structures from potential damage.
