Introduction
In the dynamic world of bridge construction, efficiency, precision, and safety are paramount. DQCRANES, a leader in innovative crane manufacturing, offers types of Rubber Tyre
gantry crane (RTG) with unmatched flexibility and strength for modern infrastructure projects.
- In the civil construction industry, these rubber gantry cranes may be employed for handling long concrete beams and bridge girders, beams, pipes, hollow cores, walls, pillars, granite and marble blocks, plates, slabs, coils, etc.
- In the industrial sector, these RTG cranes may be employed for handling generators, engines, molds, machinery, grids, pressure vessels, pipes, steel structures, blocks, plates, pillars, etc.
Gantry Cranes for Bridges & Roadways
DQCRANES has built a reputation for delivering robust, customized lifting solutions across industries. Our focus on innovation and quality ensures that each crane, including the specialized RTG, meets rigorous international standards, making it a trusted partner in complex construction environments.
For bridge construction projects, the handling of precast segments is the major application. Heavy duty gantry cranes are used mainly for handling precast segments, concrete molds, reinforcement bars, and other related raw materials and finished goods at the construction site. DQCRANES has supplied customized solutions in multiple projects with lift capacities ranging from 30t to 500t.
Understanding the RTG Crane
Unlike traditional rail-mounted gantry cranes, DQCRANES’ RTG utilizes rubber tires, providing unparalleled mobility across construction sites. This mobility is crucial for bridge projects, where space and terrain vary. The crane’s ability to traverse without fixed tracks allows seamless repositioning, adapting to the evolving needs of the site.
The Double Arch Frame Advantage
The Double Arch Frame design is a standout feature, offering:
- Enhanced Structural Integrity: The arches distribute loads evenly, reducing stress and minimizing deflection during heavy lifts.
- Increased Workspace: The design allows a wider span, enabling the crane to operate over broad sections of a bridge deck without obstruction.
- Optimized Weight Distribution: By balancing weight, the frame supports higher capacities while maintaining stability, essential for handling massive precast concrete segments.
Tailored for Bridge Construction
- High Load Capacity: Engineered to handle heavy precast segments (up to 500 tons), ensuring efficient material handling.
- Precision Control Systems: Advanced hydraulics and automation enable millimeter accuracy, critical for aligning segments in complex bridge designs.
- Safety Mechanisms: Integrated load sensors, anti-collision systems, and emergency stops comply with global safety standards, protecting both personnel and materials.
- Environmental Adaptability: Robust tires and a sturdy frame allow operation on uneven terrain and in challenging weather conditions.
Applications in Bridge Construction
- Precast Segment Handling: Transporting and positioning large concrete sections with precision, reducing manual labor and accelerating timelines.
- Versatile Material Movement: Facilitating the efficient distribution of construction materials across expansive sites.
- Adaptive Project Phases: From initial groundwork to final assembly, the crane supports multiple stages, proving indispensable in projects like overwater bridges or elevated highways.
Advantages Over Traditional RMG Cranes
- Mobility: Eliminates the need for fixed rails, offering flexibility in layout changes.
- Cost-Effectiveness: Reduces infrastructure costs associated with rail systems and allows quicker setup.
- Customization: Adjustable span, height, and load capacity to meet specific project demands.
