The railway construction gantry crane is a professional heavy-duty lifting device specially developed for the transportation, transfer and erection of concrete span beams and bridge components during railway infrastructure construction projects. It provides reliable lifting solutions for large-scale railway bridge engineering with excellent load capacity and operational stability.
The equipment supports two flexible operation configurations: dual 450-ton/500-ton cranes working in coordination for synchronized lifting, or a single 900-ton/1000-ton crane equipped with dual lifting points to complete railway beam hoisting tasks efficiently and safely.
The complete crane system consists of main girders, rigid and flexible supporting legs, travelling assemblies, hoisting mechanisms, electrical control systems, hydraulic power systems, enclosed operating cabins, safety railings, climbing ladders and maintenance walkways, forming an integrated solution for automated and efficient beam transportation and handling operations.
Flexible structural configurations for different construction scenarios
Available in two structural types: rubber-tyred mobile type and fixed rail-mounted type. The crane can adapt to different railway construction environments and project requirements with excellent application flexibility.
Full hydraulic drive and multi-directional travelling system
The crane adopts full hydraulic drive for travelling, steering and lifting operations, providing stable and powerful power output. It supports straight movement, oblique travelling and random walking modes for enhanced on-site maneuverability.
Compact structure with high construction efficiency
The optimized structural layout provides excellent site adaptability, high construction efficiency and minimal occupation of working space, making it suitable for complex railway construction environments.
Customized bridge beam lifting spreader system
Equipped with professional customized spreaders specially designed for large-scale concrete bridge beam transportation and erection, ensuring safe and reliable heavy-load handling.
High-capacity lifting with dual crane and dual trolley coordination
The dual-crane and dual-trolley collaborative configuration supports a maximum lifting height of 30 meters, meeting demanding railway bridge construction requirements.
Low foundation pressure under heavy-load operation
Under 900-ton full-load working conditions, the maximum single-wheel load is controlled within 22 tons, effectively reducing foundation pressure and improving construction safety.
Flexible rail-mounted steering conversion
The rail-mounted model supports 90° steering switching, enabling conversion between horizontal and vertical travelling directions for flexible route adjustment.
Four-point lifting and three-point balancing technology
Adopts four-point lifting and three-point balancing technology to ensure uniform force distribution on steel wire ropes and maintain stable load-bearing performance during beam handling.
High-precision beam placement control
The crane achieves high-precision positioning during beam lowering and placement, satisfying strict bridge erection accuracy requirements.
Hydraulic trolley propulsion and diversified lifting modes
The trolley adopts hydraulic propulsion technology to provide diversified lifting methods and effectively reduce overall project operating costs.
Intelligent multi-unit lifting coordination and safety protection
Equipped with four independent hoisting units, supporting single-unit operation, dual-unit synchronous linkage and four-unit combined operation. All hardware and software systems adopt interlock protection technology to guarantee safe and reliable operation.
